The Russian station, Vostok, sits on the polar plateau. The coldest temperature ever recorded on Earth was -89.2 degrees Celsius (-128.6 degrees Fahrenheit), measured at Vostok in 1983. An even lower temperature, -93.2 degrees Celsius (-135.8 degrees Fahrenheit) was recorded near the station using satellite data from August 10, 2010.

  • On July 21, 1983, Russian scientists recorded the lowest temperature in the world: -89 degrees Celsius (-129 degrees Fahrenheit), in Vostok, a research station in Antarctica. This was the actual temperature of the air, without wind-chill, during the Antarctic winter.

    Scientists have since learned that specific weather patterns contributed to Vostok Station’s unusual chill. Cold air circled the station, with almost no clouds above. Warmer air could not circulate. Vostok Station happens to be in a spot of extreme cold, even for Antarctica!
