The highest temperature ever recorded on Antarctica was 19.8 °C (67.6 °F) recorded at Signy Research Station, Signy Island on 30 January 1982. [2] [3] The highest temperature on the Antarctic mainland was 18.3 °C (64.9 °F) at the Esperanza Base (Argentina) on 6 February 2020.
Therefore, on the basis of altitude, it is expected that temperature averaged across Antarctica will be lower than temperature averaged across the Arctic. While the Arctic does have some high elevation areas (e.g. on Greenland), these make up a small proportion of its total area.
By far the coldest continent, Antarctica has winter temperatures that range from −128.6 °F (−89.2 °C), the world’s lowest recorded temperature, measured at Vostok Station (Russia) on July 21, 1983, on the high inland ice sheet to −76 °F (−60 °C) near sea level.
Temperatures are higher than many non-Antarctic continental areas even in winter, summer temperatures kept low due to ice and snow cover. Precipitation can be heavy, winds often very strong - katabatic. e.g. Mawson, 67°36'S, 62°55E, average temperature -11.9°C, range 18.9°C.
The highest recorded temperatures ever measured on the continent is 18.3 °C (64.9 °F), recorded at the Argentine base of Esperanza (see below) in February 2020. There is then an unusually mild area, located closer to the South Pole, the McMurdo Dry Valleys, at a latitude of 77 degrees South, near McMurdo station.
Mar 28, 2022 · 🔥 The recent extraordinary heatwave in Antarctica appears to have set a new World Record for the largest temperature excess above normal (+38.5 °C / +69.3 °F) ever measured at an established...
Aug 9, 2023 · The highest temperature ever recorded in Antarctica was 15 C (59 F). Antarctica has just two seasons: summer and winter. Antarctica has six months of daylight in its summer and six months of darkness in its winter. The seasons are caused by the tilt of Earth’s axis in relation to the sun. The direction of the tilt never changes.
