The average high in Antigua is 31ÂºC in September so itâs perfect if you love the heat. Temperatures only drop to 25ÂºC at night so you wonât need to bring many warm clothes. The sea temperatureâs 29ÂºC, so itâs lovely for swimming, while humidityâs very high.
The warmest hours on the island are midday during the summer time. Antigua's weather is not influenced by diverse terrain as much as it is by the lack of fresh water; the island is one of the driest and sunniest islands in the Caribbean. Droughts are common, as is low-humidity. Still, most weather reports will anticipate daily rain on the island.
