What place has the most rainfall?
Cherrapunji
Cherrapunji has often been credited as being the wettest place on Earth, but for now nearby Mawsynram currently holds that distinction. Cherrapunji still holds the all-time record for the most rainfall in a calendar month and in a year, however: it received in July 1861 and between 1 August 1860 and 31 July 1861.
Stans
Stans has an average of 137.7 days of rain per year and on average receives of precipitation. The wettest month is August when Stans receives an average of of precipitation on 13.6 days. The month with the most days of precipitation is June, with an average of 14.2, but with only of precipitation. The driest month of the year is January with an average of of precipitation over 13.6 days.
Wolfstein, Rhineland-Palatinate
Yearly precipitation in Wolfstein amounts to 729 mm, which falls into the middle third of the precipitation chart for all Germany. At 46% of the German Weather Service's weather stations, lower figures are recorded. The driest month is April. The most rainfall comes in June. In that month, precipitation is 1.4 times what it is in April. Precipitation varies only slightly and is spread extremely evenly over the year. Only at 1% of the weather stations are lower seasonal recorded.

Geography of Africa
The rainfall zones are, however, somewhat deflected from a due west-to-east direction, the drier northern conditions extending southwards along the east coast, and those of the south northwards along the west. Within the equatorial zone certain areas, especially on the shores of the Gulf of Guinea and in the upper Nile basin, have an intensified rainfall, but this rarely approaches that of the rainiest regions of the world. The rainiest district in all Africa is a strip of coastland west of Mount Cameroon, where there is a mean annual rainfall of about as compared with a mean of at Cherrapunji, in Meghalaya, India.
Kastellaun
Yearly precipitation in Kastellaun amounts to 755 mm, which falls into the middle third of the precipitation chart for all Germany. At 53% of the German Weather Service’s weather stations, lower figures recorded. The driest month is April. The most rainfall comes in June. In that month, precipitation is 1.4 times what it is in April. Precipitation varies only slightly and is spread very evenly throughout the year. Only at 1% of the weather stations are lower seasonal recorded.
Andalusia
Annual rainfall in the Sierra de Grazalema has been measured as high as in 1963, the highest ever recorded for any location in Iberia. Andalusia is also home to the driest place in continental Europe, the Cabo de Gata, with only of rain per year.
Andagoya
Every month of the year has at least 495 millimeters (19.5 inches) of average precipitation (March and December both averaging this figure), with the wettest month (April) averaging 663 millimeters (26.1 inches). Average annual precipitation is 7,089 millimeters (279.1 inches), and more rain falls at night than during the day, the reverse of what is true in most places that have tropical rain forest climates.
Canberra
Annual rainfall is the third lowest of the capital cities (after Adelaide and Hobart) but is spread fairly evenly over the seasons, with late spring bringing the highest rainfall. Thunderstorms occur mostly between October and April, owing to the effect of summer and the mountains. The area is not very windy and the breeze is at its strongest from August to November. Canberra is less humid than the nearby coastal areas.
Klausen, Germany
Yearly precipitation in Klausen amounts to 749 mm, falling into the middle third of the precipitation chart for all Germany. At 51% of the German Weather Service’s weather stations, lower figures are recorded. The driest month is February. The most rainfall comes in August. In that month, precipitation is 1.4 times what it is in February. Precipitation varies only minimally and is spread out quite evenly throughout the year.
Jeli District
Batu 13 Jeli is the wettest place in Malaysia with more than of mean rainfall annually. In 2011 of rainfall was recorded in Batu 13 Jeli, the highest annual rainfall recorded in Malaysia.
Tourism in Azad Kashmir
This region receives rainfall in both winters and summers. Muzaffarabad and Pattan are among the wettest areas of the state. Throughout most of the region, the average rainfall exceeds 1400 mm, with the highest average rainfall occurring near Muzaffarabad (around 1800 mm). During summer, monsoon floods of the Jhelum and Leepa river are common, due to high rainfall and melting snow.
Rain
The urban heat island effect leads to increased rainfall, both in amounts and intensity, downwind of cities. Global warming is also causing changes in the precipitation pattern globally, including wetter conditions across eastern North America and drier conditions in the tropics. Antarctica is the driest continent. The globally averaged annual precipitation over land is , but over the whole Earth it is much higher at . Climate classification systems such as the Köppen classification system use average annual rainfall to help differentiate between differing climate regimes. Rainfall is measured using rain gauges. Rainfall amounts can be estimated by weather radar.
Thusis
Thusis has an average of 101.6 days of rain per year and on average receives of precipitation. The wettest month is August during which time Thusis receives an average of of precipitation. During this month there is precipitation for an average of 10.7 days. The month with the most days of precipitation is June, with an average of 10.7, but with only of precipitation. The driest month of the year is February with an average of of precipitation over 10.7 days.
Climate of Argentina
With an average annual precipitation of , Lago Frías in Río Negro Province is considered to be the wettest place in Argentina. Although an average annual precipitation of has been recorded in Lago Tromen in Neuquén Province, the validity of the data is dubious owing to fewer years of data. Lago Frías also has the record for wettest monthly precipitation in Argentina: of precipitation was recorded in May 1951. In contrast, the driest place is Angualasto, San Juan Province, which only receives of precipitation a year. The highest recorded one-day rainfall total occurred on April 2, 2013, when of rain fell in La Plata at the La Plata Astronomical Observatory, causing massive flooding and power outages.
Earth rainfall climatology
The El Niño-Southern Oscillation affects the precipitation distribution, by altering rainfall patterns across the West, Midwest, the Southeast, and throughout the tropics. There is also evidence that global warming is leading to increased precipitation to the eastern portions of North America, while droughts are becoming more frequent in the tropics and subtropics. The eastern half of the contiguous United States east of the 98th meridian, the mountains of the Pacific Northwest, and the Sierra Nevada range are the wetter portions of the nation, with average rainfall exceeding per year. The drier areas are the Desert Southwest, Great Basin, valleys of northeast Arizona, eastern Utah, central Wyoming, eastern Oregon and Washington and the northeast of the Olympic Peninsula. The Big Bog on the island of Maui receives, on average, every year, making it the wettest location in the US, and all of Oceania.
Climate of Paraguay
Fairly evenly distributed rain falls in the Paranaense region. Although local meteorological conditions play a contributing role, rain usually falls in dominant tropical air masses. The least rain falls in August, when averages in various parts of the region range from to . The two periods of maximum precipitation are March through May and October to November.
Oahu
Oʻahu is also known for having the longest rain shower in history, which lasted for 200 consecutive days. Kāneʻohe Ranch, Oʻahu, Hawaiʻi reported 247 straight days with rain from August 27, 1993 to April 30, 1994. The island has many nicknames one of them being "rainbow state." This is because rainbows are a common sight in Hawaiʻi due to the frequent rain showers. The average temperature in Oʻahu is around and the island is the warmest in June through October. The weather during the winter is cooler, but still warm with an average temperature of .
Natural hazards in Colombia
Rainfall is heaviest in the Pacific lowlands and in parts of eastern Colombia, where rain is almost a daily occurrence and rain forests predominate. Precipitation exceeds 760 centimeters annually in most of the Pacific lowlands, making this one of the wettest regions in the world. The highest average annual precipitation in the world is estimated to be in Lloro, Colombia, with 13,299 mm (523.9 inches). In eastern Colombia, it decreases from 635 centimeters in portions of the Andean piedmont to 254 centimeters eastward. Extensive areas of the Caribbean interior are permanently flooded, more because of poor drainage than because of the moderately heavy precipitation during the rainy season.
The Caribbean Region of Colombia, valleys of Magdalena river and Cauca river and the eastern savannahs are prone to floods during the two main monsoon seasons (April and November). The opposite phenomenon of drought is also frequent. January through March and July through September are the dry seasons, when abnormally dry periods cause shortage in the water supply to crops and urban centers.
Climate of India
The average annual precipitation of in the village of Mawsynram, in the hilly northeastern state of Meghalaya, is the highest recorded in Asia, and possibly on Earth. The village, which sits at an elevation of , benefits from its proximity to both the Himalayas and the Bay of Bengal. However, since the town of Cherrapunji, to the east, is the nearest town to host a meteorological office—none has ever existed in Mawsynram—it is officially credited as being the world's wettest place. In recent years the Cherrapunji-Mawsynram region has averaged between of rain annually, though Cherrapunji has had at least one period of daily rainfall that lasted almost two years. India's highest recorded one-day rainfall total occurred on 26 July 2005, when Mumbai received more than ; the massive flooding that resulted killed over 900 people.
Oberwesel
Yearly precipitation in Oberwesel amounts to 604 mm, which is very low, falling into the lowest fourth of the precipitation chart for all Germany. Only at 22% of the German Weather Service’s weather stations are even lower figures recorded. The driest month is February. The most rainfall comes in June. In that month, precipitation is 1.6 times what it is in February. Precipitation varies only slightly. At only 1% of the weather stations are lower seasonal recorded.
Ventura River
Rainfall varies geographically, seasonally, and from year to year. Median annual precipitation is in the lower watershed, in the middle watershed, and in the upper watershed. However, even in the subhumid upper basin, rainfall is infrequent – falling on as few days in a year as in hot, arid Phoenix, Arizona – but when rain does fall it can be extremely heavy with totals of in a week not uncommon in the middle and upper basins. Consequently, cycles of drought and flood are the norm: as an illustration, in the main settlement of Ojai since 1906, 67 percent of the years have had less than the mean rainfall.
Climate of Alabama
The amount of precipitation is greatest along the coast (62 inches/1,574 mm) and evenly distributed through the rest of the state (about 52 inches/1,320 mm). Much of the rainfall is produced by thunderstorms and, occasionally, by hurricanes and other tropical disturbances. In central and northern Alabama, average monthly precipitation amounts are highest from November to April, typically peaking in December or March, as at Huntsville (December maximum) or Birmingham (March maximum), with August to October the driest months. Along the coast, summer thunderstorm rains are markedly more frequent and tropical weather systems are a threat from July to October. Accordingly, at Mobile, virtually the wettest city annually anywhere in the eastern United States (wetter than even Miami, FL with its drier winters), monthly average precipitation peaks in July and August, but virtually the entire year is wet, with October a slightly drier month.
Climate of South Africa
Climatic zones are often referred to by the seasonal pattern of rainfall. The winter rainfall region is confined to a relatively small area in the south-west, the Western Cape area, where gentle rain falls from May to August but the summers are dry. The summer rainfall region is the largest, being most of the country north of the coastal areas and the north west arid desert. Rain fall from October to February and is often heavy, with the amount of precipitation increasing from west to east. The summer and winter rainfall region is the Eastern Cape. The arid regions are in the north-west, with the driest areas being the north-west coast. Vegetation tends to vary by climatic zone, and these also correspond to the horticultural zones.
Hayton, Allerdale
Due to its location on the North West coast and the mountainous geography of the area, the Lake District is the wettest region in the UK. It receives on average over 2,000mm of rainfall every year however there local variation across the region. Typically in the area surrounding Hayton, the most rainfall occurs in the months February and October; with an average of 109mm in each month. The driest month is July with an annual average of 58mm however throughout the year there is average of 18 rainy/ drizzle days per month. Annual daytime temperatures range from 7 °C in February to highs of 17 °C in June and then 9 °C in November
Ibb Governorate
Owing to the way in which it captures the upper-level southwestern monsoonal flow during the months from April to October, Ibb governorate is the wettest place in Arabia. Though meteorological data are exceedingly poor and even of questionable accuracy, the annual precipitation is probably more than 1,000 mm (40 inches) and some estimate suggest it could be as high as 1,500mm (60 inches). There is little rain from November to February, but for the rest of the year there is probably at least 100mm (4 inches) of rain per month. Temperatures are warm, averaging about 30 °C (86 °F) in the day but nights are quite cool.
Breitenheim
Yearly precipitation in Breitenheim amounts to 747 mm, which falls into the middle third of the precipitation chart for all Germany. At 51% of the German Weather Service's weather stations, lower figures are recorded. The driest month is February. The most rainfall comes in June. In that month, precipitation is 1.6 times what it is in February. Precipitation varies hardly at all. At only 7% of the weather stations are lower seasonal recorded.
Dublin
Dublin's sheltered location on the east coast makes it the driest place in Ireland, receiving only about half the rainfall of the west coast. Ringsend in the south of the city records the lowest rainfall in the country, with an average annual precipitation of , with the average annual precipitation in the city centre being . The main precipitation in winter is rain; however snow showers do occur between November and March. Hail is more common than snow. The city experiences long summer days and short winter days. Strong Atlantic winds are most common in autumn. These winds can affect Dublin, but due to its easterly location, it is least affected compared to other parts of the country. However, in winter, easterly winds render the city colder and more prone to snow showers.
Chandgad
Chandgad is located at in the Kolhapur district of Maharashtra.
Chandgad is the southernmost taluka for Kolhapur district. Chandgad receives more rainfall compared to any other town of Kolhapur district, receives nearly 3000 mm of rainfall under the direct influence of the Arabian Sea branch of the South-West monsoon. Rainy season period is from June to September. The rains subside in September, with the occasional rainfall in October and November.
Simão Dias
The region is located in the Drought Polygon, with average annual temperature of 24.1 °C, but in winter the temperature can vary between 9 and 18 degrees. An interesting factor is that Simão Dias is the coldest city in the Sergipe. The average precipitation of rainfall per year is 880 mm, most prevalent from March to August (autumn-winter). The relief is represented by municipal pediplanos with occasional ridges and tabular forms, the city has many caves and caverns. The municipality comprises capoeira vegetation, scrub, grasslands and fields and traces of dirty Mata. The municipality is inserted in the river basins Vaza-Barris River and Piauí, with major rivers across the river Vaza-Barris, Jacaré rivers and Caiçá.[5]
Western Norway
Western Norway is one of the wettest regions in Europe, with precipitation in the mountains near the coast of about 3,500 mm per year on average, and exceeding 5,000 mm in peak years. In Bergen city the average precipitation is 2,250 mm per year [1]. The wet climate is partly due to the Gulf Stream, which also gives this region a milder winter than other parts of Norway, with rain being more common than snow in the winter.
Earth rainfall climatology
Most of Australia is semi-arid or desert, making it the world's driest continent. The movement of the monsoon trough is linked to the peak of the rainy season within the continent. Northern portions of the continent see the most rainfall, which is concentrated in the summer months. During winter and spring southern Australia sees its maximum rainfall. The interior desert sees its greatest rainfall during spring and summer. The wettest spot is Mount Bellenden Ker in the north-east of the country records an average of per year, with over of rain recorded in the year 2000. While Melbourne is thought of as being significantly wetter than Sydney, Sydney receives an average of 1212 mm (47.8 in) of rain per year compared to Melbourne's 650 mm (25.5 in), although Sydney is significantly sunnier and receives less days of rain.
Rheinböllen
Yearly precipitation in Rheinböllen amounts to 695 mm. This falls into the middle third of the precipitation chart for all Germany. Only at 39% of the German Weather Service's weather stations are lower figures recorded. The driest month is February. The most rainfall comes in June. In that month, precipitation is 1.6 times what it is in February. Precipitation varies only slightly. Only at 2% of the weather stations are lower seasonal recorded.
Rain
In Hawaii, Mount Waiʻaleʻale, on the island of Kauai, is notable for its extreme rainfall, as it is amongst the places in the world with the highest levels of rainfall, with . Systems known as Kona storms affect the state with heavy rains between October and April. Local climates vary considerably on each island due to their topography, divisible into windward ("Koolau") and leeward ("Kona") regions based upon location relative to the higher mountains. Windward sides face the east to northeast trade winds and receive much more rainfall; leeward sides are drier and sunnier, with less rain and less cloud cover.
Düngenheim
Yearly precipitation in Düngenheim amounts to 729 mm, which falls into the middle third of the precipitation chart for all Germany. At 47% of the German Weather Service’s weather stations, lower figures are recorded. The driest month is September. The most rainfall comes in November. In that month, precipitation is 1.4 times what it is in September. Precipitation varies only minimally and is spread quite evenly throughout the year. At only 1% of the weather stations are lower seasonal are recorded.
List of wettest tropical cyclones in the United States
The heaviest rainfall to occur in 24 hours was measured in Yankeetown during Hurricane Easy in 1950, which caused of precipitation. This is also the highest known point storm total maximum related to any tropical cyclone which has impacted Florida, and by itself would be the highest known rainfall total for any month, or any 24 hour period, from any location within Florida. This rainfall amount remained the national 24-hour rainfall record until Tropical Storm Claudette's landfall in 1979.
Riau
In general, Riau has a wet tropical climate influenced by two seasons, the rainy season and the dry season. The average rainfall received by Riau Province is between 2,000 - 3,000 mm / year with an average rainfall per year of 160 days. The most rainy areas are Rokan Hulu and Pekanbaru. Meanwhile, the area that received the least rain was Siak District.

Where
Namibia
Namibia is the driest country in sub-Saharan Africa and depends largely on groundwater. With an average rainfall of about per annum, the highest rainfall occurs in the Caprivi in the northeast (about per annum) and decreases in a westerly and southwesterly direction to as little as and less per annum at the coast. The only perennial rivers are found on the national borders with South Africa, Angola, Zambia, and the short border with Botswana in the Caprivi. In the interior of the country, surface water is available only in the summer months when rivers are in flood after exceptional rainfalls. Otherwise, surface water is restricted to a few large storage dams retaining and damming up these seasonal floods and their runoff. Where people do not live near perennial rivers or make use of the storage dams, they are dependent on groundwater. Even isolated communities and those economic activities located far from good surface water sources, such as mining, agriculture, and tourism, can be supplied from groundwater over nearly 80% of the country.
Rainfall in Karnataka
The state of Karnataka in India has a bittersweet relationship with rains. While its regions of Malnad and Coastal Karnataka receive copious amount of rainfall; its north Bayaluseemae region in the Deccan Plateau is one of the most arid regions in the country. Most of the rains received in the state is during the monsoon season. Being an agrarian economy with a large percentage of its citizens engaged in agriculture, the failure of rains can have a crippling effect on the economy of the state. Apart from the benefits in agriculture, the Government of Karnataka has tried to avail other benefits of rainfall using scientific methods. An example of this is the project, "Rainwater Harvesting in Rural Karnataka" which is initiated by the Karnataka State Council for Science and Technology and is one of the largest rainwater harvesting projects in the world. Agumbe in the Shimoga district , Amagaon in Uttara Kannada District, Hulikal again in Shimoga district and Talakaveri in Madikeri are some of the known places with the highest annual rainfall in South India. Of this Amagaon has received over 10000 mm rain fall twice in 10 years.
River Trent
In terms of rainfall the Derwent receives the highest annual average rainfall, whereas the Devon, which has the lowest average rainfall is the driest catchment of those tabulated.
Earth rainfall climatology
The annual average rainfall maxima across the continent lie across the northwest from northwest Brazil into northern Peru, Colombia, and Ecuador, then along the Atlantic coast of the Guyanas and far northern Brazil, as well as within the southern half of Chile. Lloró, a town situated in Chocó, Colombia, is probably the place with the largest measured rainfall in the world, averaging 13,300 mm per year (523.6 in). In fact, the whole Department of Chocó is extraordinarily humid. Tutunendo, a small town situated in the same department, is one of the wettest places on earth, averaging 11,394 mm per year (448 in); in 1974 the town received 26,303 mm (86 ft 3½ in), the largest annual rainfall measured in Colombia. Unlike Cherrapunji, which receives most of its rainfall between April and September, Tutunendo receives rain almost uniformly distributed throughout the year. The months of January and February have somewhat less frequent storms. On average, Tutunendo has 280 days with rainfall per year. Over ⅔ of the rain (68%) falls during the night. The average relative humidity is 90% and the average temperature is 26.4 °C. Quibdó, the capital of Chocó, receives the most rain in the world among cities with over 100,000 inhabitants: per year. Storms in Chocó can drop 500 mm (19.7 in) of rainfall in a day. This amount is more than falls in many cities in a year's time. The Andes mountain range blocks Pacific moisture that arrives in that continent, resulting in a desertlike climate just downwind across western Argentina.
Victoria (Australia)
Rain is heaviest in the Otway Ranges and Gippsland in southern Victoria and in the mountainous northeast. Snow generally falls only in the mountains and hills in the centre of the state. Rain falls most frequently in winter, but summer precipitation is heavier. Rainfall is most reliable in Gippsland and the Western District, making them both leading farming areas. Victoria's highest recorded daily rainfall was at Tidal River in Wilsons Promontory National Park on 23 March 2011.
Dackenheim
Yearly precipitation in Dackenheim amounts to 534 mm, which is very low, falling into the lowest tenth of the precipitation chart for all Germany. Only at 8% of the German Weather Service’s weather stations are even lower figures recorded. The driest month is January. The most rainfall comes in May. In that month, precipitation is 1.9 times what it is in January. Precipitation otherwise hardly varies over the year. At 32% of the weather stations, lower seasonal are recorded.
Climate of Australia
Victoria is the wettest Australian state after Tasmania. Rainfall in Victoria increases from north to south, with higher averages in areas of high altitude. Median annual rainfall exceeds in some parts of the north-east but is less than in the Mallee.
Geography of Karnataka
The southwest monsoon accounts for almost 80% of the rainfall that the state receives. The annual rainfall across the state ranges from low 50 cm to copious 350 cm. The districts of Bijapur, Raichur, Bellary and Southern half of Gulbarga experience the lowest rainfall ranging from 50 to 60 cm while the west coastal region and Malenadu enjoy the highest rainfall. Hulikal in the Western Ghats experiences the heaviest rainfall in the country next only to Cherrapunji.
Imnajbu
Precipitation is heaviest during the non-summer months brought in by the typhoons that frequent the area. Imnajbu's annual rainful varies, but is highest in the northwest and lowest in the southeast. The heaviest rainfuls happen in a belt lying inland from Mount Vatuhayao in the central highlands to Mount Mayvatek in the north central region.
Kliding
Yearly precipitation in Kliding amounts to 768 mm, which falls into the middle third of the precipitation chart for all Germany. At 56% of the German Weather Service’s weather stations, lower figures are recorded. The driest month is April. The most rainfall comes in June. In that month, precipitation is 1.5 times what it is in April. Precipitation varies only slightly. Only at 1% of the weather stations are even lower seasonal recorded.
Nohfelden
The annual rainfall is , which is in the upper tenth of the values recorded by the measuring stations of the German Weather Service. The driest month is April; It rains the most in December. The rainiest month is about 1.8 times more rainy than the driest month. The seasonal precipitation fluctuations are in the upper third in Germany.
Sonoma County, California
These microclimates are evident during the rainy seasons as well, with great variation in the amount of rainfall throughout the county. Generally, all of Sonoma County receives a fair amount of rain, with much of the county receiving between about , comparable to areas such as Sonoma and Petaluma, and roughly normal for Santa Rosa. However, certain areas, particularly in the north-west portion of the county around the Russian River, receive significantly more rainfall. The Guerneville area, for example, typically receives about of rain a year, with annual rain occasionally going as high as . Nearby Cazadero typically receives about of rain a year, many times has reached over a year, and sometimes over of rain a year. The Cazadero region is the second wettest place in California after Gasquet.
Effects of global warming on South Asia
Meghalaya- meaning 'Abode of the Clouds' in Hindi—is home to the towns of Cherrapunji and Mawsynram, which are credited with being the wettest places in the world due to their high rainfall. But scientists state that global climate change is causing these areas to experience an increasingly sparse and erratic rainfall pattern and a lengthened dry season, affecting the livelihoods of thousands of villagers who cultivate paddy and maize. Some areas are also facing water shortages.
Thailand
Most of the country receives a mean annual rainfall of . However, certain areas on the windward sides of mountains such as Ranong province in the west coast of southern Thailand and eastern parts of Trat Province receive more than of rainfall per year. The driest areas are on the leeward side in the central valleys and northernmost portion of south Thailand where mean annual rainfall is less than . Most of Thailand (north, northeast, central and east) is characterized by dry weather during the northeast monsoon and abundant rainfall during the southwest monsoon. In the southern parts of Thailand, abundant rainfall occurs in both the northeast and southwest monsoon seasons with a peak in September for the western coast and a peak in November–January on the eastern coast.
Rain
Analysis of 65 years of United States of America rainfall records show the lower 48 states have an increase in heavy downpours since 1950. The largest increases are in the Northeast and Midwest, which in the past decade, have seen 31 and 16 percent more heavy downpours compared to the 1950s. Rhode Island is the state with the largest increase, 104%. McAllen, Texas is the city with the largest increase, 700%. Heavy downpour in the analysis are the days where total precipitation exceeded the top 1 percent of all rain and snow days during the years 1950–2014
Seattle
In November, Seattle averages more rainfall than any other U.S. city of more than 250,000 people; it also ranks highly in winter precipitation. Conversely, the city receives some of the lowest precipitation amounts of any large city from June to September. Seattle is one of the five rainiest major U.S. cities as measured by the number of days with precipitation, and it receives some of the lowest amounts of annual sunshine among major cities in the lower 48 states, along with some cities in the Northeast, Ohio and Michigan. Thunderstorms are rare, as the city reports thunder on just seven days per year. By comparison, Fort Myers, Florida, reports thunder on 93 days per year, Kansas City on 52, and New York City on 25.
Ecoregions of Zambia
Rainfall amount is the most important determinant of the type and distribution of ecoregions. Zambia experiences good rainfall, with extremes of 500 to 1400 mm (most areas fall into the range 700 to ) in a distinct rainy season of four to six months centred on January, when the moist intertropical convergence zone is over the country. The highest rainfall is in the north (about 1200 mm –- all figures are annual amounts), especially the north-west (1400 mm), decreasing towards the south (around 700 mm); the driest areas are in the Luangwa and middle Zambezi valleys (500 mm). None of the country is arid.
Idar-Oberstein
Yearly precipitation in Idar-Oberstein amounts to 774 mm, falling into the middle third of the precipitation chart for all Germany. At 57% of the German Weather Service's weather stations, lower figures are recorded. The driest month is April. The most rainfall comes in December. In that month, precipitation is 1.6 times what it is in April. Precipitation hardly varies at all and is evenly spread throughout the year. At only 13% of the weather stations are lower seasonal recorded.
Climate of Indonesia
Prevailing wind patterns interact with local topographic conditions to produce significant variations in rainfall throughout the archipelago. In general, western and northern parts of Indonesia experience the most precipitation, since the north- and westward-moving monsoon clouds are heavy with moisture by the time they reach these more distant regions. Western Sumatra, Java, Bali, the interiors of Kalimantan, Sulawesi, and Papua are the most predictably damp regions of Indonesia, with rainfall measuring more than per year. In part, this moisture originates on high mountain peaks that trap damp air. The city of Bogor, near Jakarta, lays claim to having the world's highest number of thunderstorm days per year—322. On the other hand, the islands closest to Australia—including Nusa Tenggara and the eastern tip of Java—tend to be dry, with some areas experiencing less than per year. To complicate the situation, some of the islands of the southern Malukus experience highly unpredictable rainfall patterns, depending on local wind currents.
Earth rainfall climatology
Rainfall varies widely both by location and season. Arid or semiarid conditions are encountered in the Baja California Peninsula, the northwestern state of Sonora, the northern altiplano, and also significant portions of the southern Altiplano. Rainfall in these regions averages between per year, with lower amounts across Baja California Norte. Average rainfall totals are between in most of the major populated areas of the southern altiplano, including Mexico City and Guadalajara. Low-lying areas along the Gulf of Mexico receive in excess of of rainfall in an average year, with the wettest region being the southeastern state of Tabasco, which typically receives approximately of rainfall on an annual basis. Parts of the northern altiplano, highlands and high peaks in the Sierra Madre Occidental and the Sierra Madre Oriental occasionally receive significant snowfalls.
Geography of Atlanta
Typical of the southeastern U.S., Atlanta receives abundant rainfall, which is relatively evenly distributed throughout the year, though spring and early fall are markedly drier. Average annual rainfall is about , with late winter and early spring (as well as July) being the wettest and fall (especially October) being the driest. Despite having far fewer rainy days, average yearly rainfall is higher here than in the Seattle area, especially due to heavy thunderstorms and occasional tropical depressions.
Kimberley (Western Australia)
The Kimberley has a tropical monsoon climate. The region receives about 90% of its rainfall during the short wet season, from November to April, when cyclones are common (especially around Broome) and the rivers flood. The annual rainfall is highest in the northwest, where Kalumburu and the Mitchell Plateau average per year, and lowest in the southeast where it is around . In the dry season, from May to October, south easterly breezes bring sunny days and cool nights. Climate change since 1967 has led to large increases of as much as per year in annual rainfall over the whole region. Recent studies suggest Asian pollution and not global warming as the cause of this increased rainfall. In 1997 and 2000 the region received especially heavy rains, leading to record flooding of the Fitzroy and other rivers.
List of wettest tropical cyclones in the United States
Tropical cyclones move into the contiguous United States from the Atlantic Ocean, the Gulf of Mexico, and the eastern Pacific Ocean. The highest rainfall totals in the country have been measured across the Gulf Coast and lower portions of the Eastern Seaboard. Intermediate amounts have been measured across the Southwest, New England, and the Midwest. The northern Great Plains and Pacific Northwest have received the lowest amounts, as those regions lie exceptionally far from the breeding grounds of Atlantic and Eastern Pacific tropical cyclones.
Climate of Australia
Rainfall records tend to be concentrated along the east coast of Australia, particularly in tropical north Queensland. The highest 24‑hour rainfall on record in Australia was in Crohamhurst on 3 February 1893. The highest monthly rainfall on record was recorded at Mount Bellenden Ker, Queensland in January 1979. The highest annual rainfall was recorded also at Mount Bellenden Ker in 2000. Additionally, the location which receives the highest average annual rainfall in Australia is Babinda in Queensland with an annual average of .
Baumholder
Yearly precipitation in Baumholder amounts to 884 mm. At 76% of the German Weather Service’s weather stations, lower figures are recorded. The driest month is April. The most rainfall comes in December. In that month, precipitation is twice what it is in April. Precipitation varies only slightly. At 46% of the weather stations, lower seasonal swings are recorded.
United States tropical cyclone rainfall climatology
The state of Texas has the highest amounts, followed by Florida, Alabama, North Carolina, and Mississippi. In the western United States, the same can be said for the remnants of Hurricane Kathleen of 1976 in California, and the remnants of Tropical Storm Nora of 1997 in Arizona. In addition, some rainfall records across the Midwest occurred during Tropical Storm Candy of 1968.
Monsoon of South Asia
Mawsynram and Cherrapunji, both in the Indian state of Meghalaya, alternate as the wettest places on Earth given the quantity of their rainfall, though there are other cities with similar claims. They receive more than 11,000 millimeters of rain each from the monsoon.
Geography of the United States
In the east, the region near the Great Lakes and the mountains of the Northeast receive the most snowfall, although such snowfall levels do not near snowfall levels in the western United States. Along the northwestern Pacific coast, rainfall is greater than anywhere else in the continental U.S., with Quinault Rainforest in Washington having an average of . Hawaii receives even more, with measured annually in the Big Bog, in Maui. The Mojave Desert, in the southwest, is home to the driest locale in the U.S. Yuma, Arizona, has an average of of precipitation each year.

During this period, the average amount of rainfall exceeds per month, and the rainiest month of all is May, when rainfall averages approximately . The driest months, between September and February, see the winds weakening and only really managing to bring light clouds. There is also less rain. The driest month is November, when rainfall averages approximately . The average rainfall during these months is between approximately .
Kentucky Bend
Rainfall is fairly heavy throughout the year due to moist air from the Gulf of Mexico being advected on the western side of the Bermuda High, plus occasional remnant depressions from hurricanes passing up the Mississippi Valley. Between 1963 and 2012 the wettest calendar year was 1990 with and the driest 2005 with . The wettest day was September 23, 2006 with in one day, and September 2006 was also the wettest month with , whilst no precipitation fell during October 1964.
Climate of the United Kingdom
Rainfall amounts can vary greatly across the United Kingdom: generally the further west and the higher the elevation, the greater the rainfall. The mountains of Wales, Scotland, the Pennines in Northern England and the moors of South West England are the wettest parts of the country, and in some of these places as much as of rain can fall annually, making these locations some of the wettest in Europe. The wettest spot in the United Kingdom is Crib Goch, in Snowdonia, which has averaged rain a year over the past 30 years. Most rainfall in the United Kingdom comes from North Atlantic depressions which roll into the country throughout the year from the west or southwest and are particularly frequent and intense in the autumn and winter. They can on occasions bring prolonged periods of heavy rain, and flooding is quite common.
Geography of Vietnam
Mean annual rainfall in the country ranges from although most places in Vietnam receive between . The majority of rainfall occurs during the rainy season, which is responsible for 80%–90% of the annual precipitation. Generally, northern parts of the country receive more rainfall than southern parts of the country. Drizzle is a weather phenomenon that is characteristic of the weather in winter in the north and north central coast. Depending on the region, the onset of the rainy season (defined as when the monthly average precipitation exceeds ) differs.
Geography of Belarus
The highest average yearly precipitation is recorded in Navahrudak (769 mm per year). The highest yearly precipitation ever recorded was in Vasilievičy (1,115 mm per year), the lowest – in Brahin (298 mm). 70% of precipitation falls from April to October. Heavy rains are common in summer. Sometimes one-day precipitation during summer rainfall exceeds average monthly precipitation. The heaviest rain ever was recorded in July 1973 in Slaŭnaje in Talachyn Raion – 148 mm in one day. The highest humidity level is observed in December and January (90%), the lowest – in May and June (65–70%) with an average level of 80%. Days with humidity lower than 30% are rare – usually less than 20 every year, with only 3–5 such days in some regions. On the contrary, there are more than 100 days with high humidity (over 80%), in some regions – up to 152. Due to high humidity, areas around Minsk and Navahrudak have from 65 to 100 foggy days every year.
Hundsbach
Yearly precipitation in Hundsbach amounts to 590 mm, which is very low, falling into the lowest fourth of the precipitation chart for all Germany. Only at 19% of the German Weather Service’s weather stations are even lower figures recorded. The driest month is February. The most rainfall comes in May. In that month, precipitation is 1.6 times what it is in February. Precipitation varies only slightly and is spread quite evenly over the year. At only 1% of the weather stations are lower seasonal recorded.
Earth rainfall climatology
Mexico has pronounced wet and dry seasons. Most of the country experiences a rainy season from June to mid-October and significantly less rain during the remainder of the year. February and July generally are the driest and wettest months, respectively. Mexico City, for example, receives an average of only of rain during February but more than in July. Coastal areas, especially those along the Gulf of Mexico, experience the largest amounts of rain in September. Tabasco typically records more than of rain during that month. A small coastal area of northwestern coastal Mexico around Tijuana has a Mediterranean climate with considerable coastal fog and a rainy season that occurs in winter.
Climate of Brazil
Brazil's most intense rain falls around the mouth of the Amazon near the city of Belém, and also in the upper regions of Amazonia where more than of rain fall every year. The warm weather lets many plant grow here. Most of Brazil has moderate rainfall of between a year, most of it coming between December and April. The driest part of the country is the northeast, where rainfall is erratic and the evaporation rate very high, making it difficult to grow crops.
List of wettest tropical cyclones in the United States
Puerto Rico has seen dramatic rainfall from tropical cyclones and their precursor disturbances. The most recent tropical cyclone-related deluge was from Hurricane Irene in August 2011, when of rain was measured at Gurabo Abajo. The heaviest rainfall noted over the past 30 years was from the precursor disturbance to Tropical Storm Isabel, when fell at Toro Negro Forest. Hurricane Eloise of 1975 dropped of rainfall at Dos Bocas, with falling in 24 hours.
Mawsynram
Under the Köppen climate classification, Mawsynram features a subtropical highland climate with an extraordinarily showery and long monsoonal season and a short dry season. Based on the data of a recent few decades, it appears to be the wettest place in the world, or the place with the highest average annual rainfall. Mawsynram receives over 10,000 millimeters of rain in an average year, and the vast majority of rain it falls during the monsoon months. A comparison of rainfalls for Cherrapunji and Mawsynram for some years is given in Table 1.
List of wettest tropical cyclones by country
This is a list of wettest tropical cyclones by country, using all known available sources. Data is most complete for Australia, Cuba, Dominican Republic, Japan, Hong Kong, Mexico, Taiwan, Yap, Chuuk, and the United States, with fragmentary data available for other countries. The French region of Réunion holds several world records for tropical cyclone and worldwide rainfall, due to the rough topography and its location in the Indian Ocean.
Geography of Mexico
Rainfall varies widely both by location and season. Arid or semiarid conditions are encountered in the Baja California Peninsula, the northwestern state of Sonora, the northern altiplano, and also significant portions of the southern altiplano. Rainfall in these regions averages between per year, although even less in some areas, particularly in the state of Baja California. Average rainfall totals are between in most of the major populated areas of the southern altiplano, including Mexico City and Guadalajara. Low-lying areas along the Gulf of Mexico receive in excess of of rainfall in an average year, with the wettest region being the southeastern state of Tabasco, which typically receives approximately of rainfall on an annual basis. Parts of the northern altiplano, highlands and high peaks in the Sierra Madres receive yearly snowfall. Citlaltépetl, Popocatépetl and Iztaccíhuatl continue to support glaciers, the largest of which is the Gran Glaciar Norte.
Climatic regions of Argentina
Mesopotamia is the wettest region in Argentina with average annual precipitation ranges from less than in the southern parts, to approximately in the eastern parts.Precipitation is slightly higher in summer than in winter, and generally decreases from east to west and from north to south. Summer (December–February) is the most humid season, with precipitation ranging from . Fall (March–May) is the rainiest season, with many places receiving over . Most of the rainfall during summer and fall is caused by convective thunderstorms. Winter (June–August) is the driest season, with a mean precipitation of throughout the region. Most of the winter precipitation is the result of synoptic scale, low pressure weather systems (large scale storms such as extratropical cyclones), particularly the "sudestada", which often bring long periods of precipitation, cloudiness, cooler temperatures, and strong winds. Snowfall is extremely rare and mainly confined to the uplands of Misiones Province where the last significant snowfall occurred in 1975 in Bernardo de Irigoyen. Spring (September–November) is similar to fall with a mean precipitation of .
Hilo, Hawaii
Hilo has a tropical rainforest climate (Köppen "Af"), with substantial rainfall throughout the course of the year. Its location on the eastern side of the island, (windward relative to the trade winds), makes it the fourth wettest designated city in the United States, behind the southeast Alaskan cities of Whittier, Ketchikan and Yakutat, and one of the wettest in the world. An average of around of rain fell at Hilo International Airport annually between 1981 and 2010, with 272 days of the year receiving some rain. Rainfall in Hilo varies with altitude, with more at higher elevations. At some weather stations in upper Hilo the annual rainfall is above .
Mettenheim, Rhineland-Palatinate
Yearly precipitation in Mettenheim amounts to 558 mm, which is low, falling into the lowest fourth of the precipitation chart for all Germany. Only at 12% of the German Weather Service’s weather stations are even lower figures recorded. The driest month is January. The most rainfall comes in July. In that month, precipitation is twice what it is in January. Precipitation varies moderately. At 51% of the weather stations, lower seasonal are recorded.
Moro, Oregon
Precipitation is very low due to the rain shadow of the Cascades and the valley location, being around lower than even the driest areas in the Olympic rain shadow like Sequim. The wettest month on record has been December 1964 with , but no other month has passed . The wettest "rain year" has been from July 1947 to June 1948 with and the driest from July 1967 to June 1968 with , whilst he most precipitation in one day has been on January 9, 1953.
Lake District
Although the entire region receives above average rainfall, there is a wide disparity between the amount of rainfall in the western and eastern lakes, as the Lake District experiences relief rainfall. Seathwaite, Borrowdale is the wettest inhabited place in England with an average of of rain a year, while nearby Sprinkling Tarn is even wetter, recording over per year; by contrast, Keswick, at the end of Borrowdale receives every year, and Penrith (just outside the Lake District) only . March to June tend to be the driest months, with October to January the wettest, but at low levels there is relatively little difference between months.
Hurricane Carla
In Nebraska, rainfall peaked at in Hubbrell, making Carla the rainiest tropical cyclone in the state. Heavy precipitation also fell in Missouri, especially in Brookfield, Lee's Summit, and Pleasant Hill. The maximum rainfall total in Missouri was in Concordia. One fatality was reported in Missouri, though the cause of death is unknown. Rainfall in Iowa peaked at near Chariton, making Carla the rainiest tropical cyclone in the state. Up to of rain fell in a 12-hour period in the Lower Peninsula of Michigan, mostly between Cheboygan and Grand Rapids. However, the Weather Prediction Center indicated precipitation amounts of in Boyne Falls. Regardless, Carla is the wettest tropical cyclone in the history of Michigan. Despite, the rainfall, flooding in Michigan was relatively minimal, limited to an washed out dam in Traverse City. Precipitation in Wisconsin reached in Brodhead, causing Carla to rank as the wettest tropical cyclone in the state. Precipitation peaks in other states include in Alabama, in Arkansas, in Mississippi, and in Indiana.
Northern Norway
Autumn tend to be the wettest season in most areas, often receiving more than twice as much precipitation as does spring and early summer. Only the interior areas of Finnmark – like Karasjok – tend to be wettest in summer. The areas with the least precipitation are some inland valleys, like Dividalen in Målselv with only precip/year, and upper Saltdal and Skibotn with about the same. Inland Finnmark is the only large area with less than precipitation/year. The wettest areas are generally the Helgeland region; Lurøy on the west coast of Saltfjell averages /year.
Western United States
Annual rainfall is greater in the eastern portions, gradually tapering off until reaching the Pacific Coast where it increases again. In fact, the greatest annual rainfall in the United States falls in the coastal regions of the Pacific Northwest. Drought is much more common in the West than the rest of the United States. The driest place recorded in the U.S. is Death Valley, California.
Azad Kashmir
The region receives rainfall in both the winter and the summer. Muzaffarabad and Pattan are among the wettest areas of Pakistan. Throughout most of the region, the average rainfall exceeds 1400 mm, with the highest average rainfall occurring near Muzaffarabad (around 1800 mm). During the summer season, monsoon floods of the rivers Jhelum and Leepa are common due to extreme rains and snow melting.
Hosanagara
As this taluk is in the windward side of western ghats, this place gets heavy to heavy rainfall during June-September in the monsoon season. The average precipitation ranges from 3000-8000mm.Hulikal town gets more than 8000 mm rainfall in the year which is the wettest place in the state.
Geography of Cambodia
The total annual rainfall average is between , and the heaviest amounts fall in the southeast. Rainfall from April to September in the Tonlé Sap Basin-Mekong Lowlands area averages annually, but the amount varies considerably from year to year. Rainfall around the basin increases with elevation. It is heaviest in the mountains along the coast in the southwest, which receive from to more than of precipitation annually as the southwest monsoon reaches the coast. This area of greatest rainfall, however, drains mostly to the sea; only a small quantity goes into the rivers flowing into the basin. Relative humidity is high throughout the entire year; usually exceeding 90%. During the dry season daytime humidity rates average around 50 percent or slightly lower, climbing to about 90% during the rainy season.
Rhaunen
Yearly precipitation in Rhaunen amounts to 744 mm, which falls into the middle third of the precipitation chart for all Germany. At 50% of the German Weather Service's weather stations lower figures are recorded. The driest month is April. The most rainfall comes in November. In that month, precipitation is 1.4 times what it is in April. Precipitation varies only slightly and is spread quite evenly throughout the year. Only at 1% of the weather stations are lower seasonal recorded.
Climate of Ireland
Rainfall is the most common form of precipitation on the island, and is extremely common throughout Ireland, although some parts of the west coast receive over four times as much rain as the east coast. Rainfall in Ireland normally comes from Atlantic frontal systems which travel northeast over the island, bringing cloud and rain. Most of the eastern half of the country has between of rainfall in the year. Rainfall in the west generally averages between . In many mountainous districts rainfall exceeds per year. The wettest months almost everywhere are December and January. April is the driest month generally, but in many southern parts June is the driest.
Rain
The equatorial region near the Intertropical Convergence Zone (ITCZ), or monsoon trough, is the wettest portion of the world's continents. Annually, the rain belt within the tropics marches northward by August, then moves back southward into the Southern Hemisphere by February and March. Within Asia, rainfall is favored across its southern portion from India east and northeast across the Philippines and southern China into Japan due to the monsoon advecting moisture primarily from the Indian Ocean into the region. The monsoon trough can reach as far north as the 40th parallel in East Asia during August before moving southward thereafter. Its poleward progression is accelerated by the onset of the summer monsoon which is characterized by the development of lower air pressure (a thermal low) over the warmest part of Asia. Similar, but weaker, monsoon circulations are present over North America and Australia. During the summer, the Southwest monsoon combined with Gulf of California and Gulf of Mexico moisture moving around the subtropical ridge in the Atlantic Ocean bring the promise of afternoon and evening thunderstorms to the southern tier of the United States as well as the Great Plains. The eastern half of the contiguous United States east of the 98th meridian, the mountains of the Pacific Northwest, and the Sierra Nevada range are the wetter portions of the nation, with average rainfall exceeding per year. Tropical cyclones enhance precipitation across southern sections of the United States, as well as Puerto Rico, the United States Virgin Islands, the Northern Mariana Islands, Guam, and American Samoa.
Cambrai
Precipitation is distributed year-round, with highs in the spring and autumn, with February being the driest month. Contrasting with the rainy image of the region, the total annual precipitation is relatively small with at Cambrai-Épinoy; identical to the Montsouris Paris station, which is at the same altitude, it is less than those of Toulouse at or Nice at . However, the number of days of rain (63 in Nice, 120 in Cambrai) confirms the oceanic character of the climate.
Binghamton, New York
Binghamton is the 10th rainiest city in the United States, with 162 rainy days a year. With 212 cloudy days annually, it is also the seventh cloudiest city in the country, and the cloudiest east of the Rocky Mountains. Binghamton's proximity to the Great Lakes results in significant cloudiness and precipitation, as weather systems traveling over the lake pick up significant moisture, and cooler air masses from the west and the north culminate in a continuously unsettled weather pattern.
Villa Puerto Edén
Villa Puerto Edén has an extremely wet subpolar oceanic climate (Köppen "Cfc") and is widely reputed to be the place in the world with the highest frequency of rainfall, though according to Guinness World Records the highest frequency of rain in a year occurred at Bahia Felix, a little further south, with only eighteen rainless days in the whole of 1916. The annual rainfall is almost exactly equal to that of Little Port Walter in the similarly wet Alaska Panhandle, but is more evenly spread across the year, with a minimum average monthly rainfall of as against in Little Port Walter.
Western Washington
It is known as being far wetter in climate than the eastern portion of the state, which
is due in main to the effects of the Cascades rain shadow. The average place in Eastern Washington only receives an average of 46.87 centimeters (18.45 inches) of precipitation per year. However, the average place in Western Washington receives an average of 167.72 centimeters (66.03 inches) of precipitation per year. The average place in Western Washington gets 168 days of measurable precipitation per year. The place that receives the most recorded precipitation is Lake Quinault on the Olympic Peninsula with an average of 332.92 centimeters (131.07 inches) per year. The place that gets the most days of measurable precipitation is the Long Beach Experimental Station with an average of 215 days of measurable precipitation per year.
Climate of the United Kingdom
Parts of England are dry in global terms, which is contrary to the stereotypical view—London receives just below per annum, which is less than Rome, Sydney, or New York City. In East Anglia it typically rains on about 113 days per year. Most of the south, south-east and East Anglia receive less than of rain per year. The English counties of Essex, Cambridgeshire - as well as parts of North Yorkshire, the East Riding of Yorkshire, Suffolk and Norfolk - are amongst the driest in the UK, with an average annual rainfall of around . This is due to a mild rainshadow effect, due to mountainous parts of the South West, Wales and Cumbria blocking the moist airflow across the country to the east. In some years rainfall totals in Essex and South Suffolk can be below (especially areas around Colchester, Clacton and Ipswich) - less than the average annual rainfall in Jerusalem, Beirut and even some semi-arid parts of the world.
United States rainfall climatology
Average precipitation across the region show maxima along the coastal plain and along the mountains of the Appalachians. Between and of precipitation falls annually across the area. Seasonally, there are slight changes to precipitation distribution through the year. For example, Burlington, Vermont has a summer maximum and a winter minimum. In contrast, Portland, Maine has a fall and winter maximum, with a summer minimum in precipitation. Temporally, a maximum in precipitation is seen around three peak times: 3 a.m., 10 a.m., and 6 p.m. During the summer, the 6 p.m. peak is most pronounced.
Democratic Republic of the Congo
As a result of its equatorial location, the DRC experiences high precipitation and has the highest frequency of thunderstorms in the world. The annual rainfall can total upwards of in some places, and the area sustains the Congo Rainforest, the second-largest rain forest in the world after the Amazon. This massive expanse of lush jungle covers most of the vast, low-lying central basin of the river, which slopes toward the Atlantic Ocean in the west. This area is surrounded by plateaus merging into savannas in the south and southwest, by mountainous terraces in the west, and dense grasslands extending beyond the Congo River in the north. High, glaciated mountains (Rwenzori Mountains) are found in the extreme eastern region. 
The tropical climate also produced the Congo River system which dominates the region topographically along with the rainforest it flows through, though they are not mutually exclusive. The name for the Congo state is derived in part from the river. The river basin (meaning the Congo River and all of its myriad tributaries) occupies nearly the entire country and an area of nearly . The river and its tributaries form the backbone of Congolese economics and transportation. Major tributaries include the Kasai, Sangha, Ubangi, Ruzizi, Aruwimi, and Lulonga.
Southeast Texas
Compared to the rest of the state, Southeast Texas' climate is warmer in winter and cooler in summer. On average, the region receives more rain than other parts of the state. This can increase the humidity level in the region. The relatively mild and wet climate is largely due to the influence of the Gulf of Mexico. Average annual rainfall in the Golden Triangle is 60 inches (1,500  mm). Rainfall totals in other parts of Southeast Texas are lower, but still in excess of 40inches (1,000  mm) per year. During Tropical Storm Claudette in 1979, the city of Alvin recorded an official 24-hour rainfall total of 42 inches (1,067 mm) — the highest one-day rainfall total ever measured in the United States. Nederland received 66 inches during Harvey.
