What is Wind Chill? Wind chill is a measure of the combined effect of wind and temperature on the perceived temperature. It is defined as the temperature that a person feels based on wind speed and air temperature, and it takes into account how quickly heat is lost from exposed skin. In general, higher wind speeds can increase the rate of heat loss and make a given air temperature feel colder, while lower wind speeds can reduce the rate of heat loss and make a given air temperature feel warmer.
The average temperature at the summit of Mount Everest, the highest peak on Earth, is about -19°F (-28°C) during the day and even lower at night, reaching as low as -76°F (-60°C).
DID YOU KNOW - The coldest recorded temperature on Earth is minus 128.6 degrees Fahrenheit (minus 89.2 degrees Celsius) at the Soviet Union's Vostok Station in Antarctica on July 21, 1983
