Lowest Temperature Ever Recorded
Current Record
The lowest directly recorded air temperature on Earth’s surface is -89.2°C (-128.6°F).
- Location: Vostok Station, Antarctica.
- Date: July 21, 1983.
- Context: Recorded during a clear sky night in the polar winter.
Subglacial Extremes & Lake Vostok
While air temperatures define the standard record, subglacial environments present distinct thermal and biological conditions. Recent analysis of Lake Vostok highlights its isolation beneath ~4km of ice.

Notable High-Altitude Measurements
Satellite data suggests even lower temperatures in high-elevation interior regions where direct sensor placement is difficult.
- East Antarctic Plateau: Readings as low as -98°C (-140°F) have been inferred by satellite radiometers over ridges higher than Vostok Station.
- Verification: These figures require ground-truthing and are not considered “directly recorded” in the traditional meteorological sense pending specific probe deployment MCM Glacier.
