South Pole
In midsummer, as the sun reaches its maximum elevation of about 23.5 degrees, high temperatures at the South Pole in January average at . As the six-month "day" wears on and the sun gets lower, temperatures drop as well: they reach around sunset (late March) and sunrise (late September). In midwinter, the average temperature remains steady at around . The highest temperature ever recorded at the Amundsen–Scott South Pole Station was on Christmas Day, 2011, and the lowest was on June 23, 1982 (for comparison, the lowest temperature directly recorded anywhere on earth was at Vostok Station on July 21, 1983, though was measured indirectly by satellite in East Antarctica between Dome A and Dome F in August 2010). Mean annual temperature at the South Pole is -49.3 °C (-56.7 °F).
Saint Paul Island (Alaska)
Saint Paul's climate is strongly influenced by the cold waters of the surrounding Bering Sea, and is classified as polar (Köppen "ET") due to the raw chilliness of the summers. It experiences a relatively narrow range of temperatures, high wind, humidity and cloudiness levels, and persistent summer fog. There is high seasonal lag: February is the island's coldest month, while August is its warmest; the difference between the average low temperature in February and the average high temperature in August is only . Although the mean average temperature for the year is above freezing, at , the monthly daily average temperature remains below freezing from December to April. Low temperatures at or below occur an average of 4.7 nights per year (mostly from January to March), and the island is part of USDA Hardiness Zone 6. Extreme temperatures have ranged from on March 14, 1971, up to on August 25, 1987. Winds are strong and persistent year-round, averaging around . They are strongest from late autumn through winter, when they increase to an average of nearly , blowing mostly from the north. In the summer, they become weaker and blow primarily from the south.
