Which place on earth has the coldest temperatures for the longest periods of time?

The place on Earth with the coldest temperatures for the longest periods is typically considered to be Antarctica, specifically at a high point on the East Antarctic Plateau.

Key Facts about the Coldest Place:

• Location: The area known as the Dome Argus on the East Antarctic Ice Sheet.
• Extreme Temperatures: Satellite measurements have recorded temperatures as low as −128.6°F (−89.2°C) at Vostok Station on July 21, 1983, which is the lowest natural temperature ever recorded on Earth.
• Coldest Months: The winter months (May to August) see the most extreme cold, with temperatures often remaining well below freezing for extended periods.
• Long Duration of Cold: Due to the high elevation and the polar climate, parts of Antarctica can experience continuous cold for most of the year, especially during the long polar nights.

Other Notable Cold Places:

• Oymyakon, Russia: Known as one of the coldest inhabited places on Earth, with temperatures dropping below −50°C (−58°F).
• Yakutsk, Russia: Often cited for extreme winter temperatures but not as cold as the highest points in Antarctica.

Antarctica remains the most extreme in terms of sustained cold temperatures over long periods.
