Wind Chill Calculator
Wind makes cold air feel even colder by stripping heat from exposed skin faster. Enter the air temperature and wind speed to calculate the wind chill using the standard North American formula.
About this calculator
Calculate the wind chill temperature (how cold it actually feels) using the official National Weather Service formula based on air temperature and wind speed.
Frequently Asked Questions
What formula does this use?
This calculator uses the official North American wind chill formula adopted by the National Weather Service and Environment Canada in 2001, based on skin heat loss models.
Why doesn't wind chill apply above 50°F?
The formula is only valid for temperatures at or below 50°F and wind speeds above 3 mph, since wind has minimal cooling effect on skin in warmer conditions.
Is wind chill the same as 'feels like' temperature?
Wind chill is one component of 'feels like' temperature in cold weather. In hot weather, 'feels like' is instead calculated using the heat index, which factors in humidity.
