How wind chill is calculated
Estimate the US National Weather Service wind-chill temperature from air temperature in Fahrenheit and wind speed in miles per hour. The index applies only at or below 50°F with wind above 3 mph and assumes shade; sun exposure can change how conditions feel. At 30°F with 10 mph wind, the standard equation gives a wind chill near 21°F. The calculation validates each input and keeps its stated units explicit. It describes heat loss from exposed skin; it does not make an object colder than the air temperature. This is an estimate for the stated assumptions; confirm measurements and any applicable professional or local standards before relying on it.
WC = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275T V^0.16At 30°F with 10 mph wind, the standard equation gives a wind chill near 21°F.
Assumptions & useful context
NWS formula; shade and exposed-skin assumptions apply.
Frequently asked questions
