Climate of Antarctica

Surface temperature of Antarctica in winter and summer from the European Centre for Medium-Range Weather Forecasts

Map of average annual precipitation on Antarctica (mm liquid equivalent)

Antarctic Skin Temperature Trends between 1981 and 2007, based on thermal infrared observations made by a series of NOAA satellite sensors. Skin temperature trends do not necessarily reflect air temperature trends.

The climate of Antarctica is the coldest on Earth. Antarctica's lowest air temperature record was set on 21 July 1983, with −89.2 °C (−128.6 °F) at Vostok Station. Satellite measurements have identified even lower ground temperatures, down to −93.2 °C (−135.8 °F) at the cloud free East Antarctic Plateau. It is also extremely dry (technically a desert), averaging 166mm (6.5 in) of precipitation per year. On most parts of the continent the snow rarely melts and is eventually compressed to become the glacier ice that makes up the ice sheet. Weather fronts rarely penetrate far into the continent, because of the Katabatic winds. Most of Antarctica has an ice cap climate (Köppen EF) with very cold, generally extremely dry weather.
