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).
Amundsen–Scott South Pole Station
The Amundsen–Scott South Pole Station is a United States scientific research station at the South Pole, the southernmost place on the Earth. The station is located on the high plateau of Antarctica at an elevation of 2,835 metres (9,301 feet) above sea level and is administered by the Division of Polar Programs within the National Science Foundation under the United States Antarctic Program (USAP). It is named in honor of Norwegian Roald Amundsen and Englishman Robert F. Scott, who led separate teams that raced to become the first to the South Pole in the early 1900s.
