How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

Wind chill uses the NWS formula: WC = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275T×V^0.16, where T=°F and V=mph. It applies when T ≤ 50°F and V ≥ 3 mph.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.

Frequently asked questions

Why does wind make it feel colder?

Wind removes the thin layer of warm air your body creates near skin. It doesn't lower the actual temperature but accelerates heat loss, making it feel colder.
