<P> The lowest reliably measured temperature of a continuously occupied station on Earth of − 89.2 ° C (− 128.6 ° F) was on 21 July 1983 at Vostok Station . For comparison, this is 10.7 ° C (19.3 ° F) colder than subliming dry ice (at sea level pressure). The altitude of the location is 3,900 meters (12,800 feet). </P> <P> The lowest recorded temperature of any location on Earth's surface at 81 ° 48 ′ S 63 ° 30 ′ E ﻿ / ﻿ 81.8 ° S 63.5 ° E ﻿ / - 81.8; 63.5 was revised with new data in 2018 in nearly 100 locations, ranging from − 93.2 ° C (− 135.8 ° F) to − 98 ° C (− 144.4 ° F). This unnamed part of the Antarctic plateau, between Dome A and Dome F, was measured on August 10, 2010, and the temperature was deduced from radiance measured by the Landsat 8 and other satellites, and discovered during a National Snow and Ice Data Center review of stored data in December, 2013 but revice by researcher on June 25 2018 . This temperature is not directly comparable to the - 89.2 quoted above, since it is a skin temperature deduced from satellite - measured upwelling radiance, rather than a thermometer - measured temperature of the air 1.5 m (4.9 ft) above the ground surface . </P> <P> The highest temperature ever recorded on the Antarctic continent was 17.5 ° C (63.5 ° F) at Esperanza Base, on the Antarctic Peninsula, on 24 March 2015 . A higher temperature of 19.8 ° C (67.6 ° F) at Signy Research Station on 30 January 1982 is the record for the Antarctic region encompassing all land and ice south of 60S . </P> <P> The mean annual temperature of the interior is − 57 ° C (− 70.6 ° F). The coast is warmer; on the coast Antarctic average temperatures are around - 10 ° C (in the warmest parts of Antarctica) and in the elevated inland they average about - 55 ° C in Vostok. . Monthly means at McMurdo Station range from − 26 ° C (− 14.8 ° F) in August to − 3 ° C (26.6 ° F) in January . At the South Pole, the highest temperature ever recorded was − 12.3 ° C (9.9 ° F) on 25 December 2011 . Along the Antarctic Peninsula, temperatures as high as 15 ° C (59 ° F) have been recorded, though the summer temperature is below 0 ° C (32 ° F) most of the time . Severe low temperatures vary with latitude, elevation, and distance from the ocean . East Antarctica is colder than West Antarctica because of its higher elevation . The Antarctic Peninsula has the most moderate climate . Higher temperatures occur in January along the coast and average slightly below freezing . </P>
