Temperature
If Antarctica is known for anything, it's extreme cold: The lowest natural temperature on record—-128.6°F—was recorded at Russia's Vostok Station in 1983. Though it's generally warmer on the sea ice around Antarctica than on the continent itself, temperatures there regularly drop below 0°F, and Antarctic winds, which can reach speeds up to 200 miles per hour, or over two and a half times hurricane force, often dangerously deepen the chill. For exposed flesh, for example, if the ambient temperature is -20°F, a 10 mph breeze will make the effective temperature -46°F, while a 30 mph wind will drop it to a literally unbearable -79°F.
