Wind Chill Calculator
Find out how cold it really feels outside. Enter the air temperature and wind speed to calculate the wind chill (feels-like) temperature.
Calculates the "feels like" temperature based on wind speed. Uses the National Weather Service formula.
How It Works & Formula
The wind chill formula combines temperature (T in Celsius) and wind speed (W in km/h) to estimate heat loss from exposed skin: 13.12 + 0.6215T - 11.37W^0.16 + 0.3965T x W^0.16.
Frequently Asked Questions
What is wind chill?
Wind chill is the perceived decrease in temperature caused by wind removing heat from the body faster.
When does wind chill apply?
It is most meaningful at temperatures at or below 10 degrees Celsius with wind speeds above about 5 km/h.
Is wind chill an actual temperature?
No, it is a feels-like value that reflects how cold the air feels on exposed skin, not a physical temperature.
