Did we solve your problem today?

Wind makes cold feel colder — find the wind chill 'feels like' temperature.

The math behind it

The NWS formula combines air temperature and wind speed (valid for T ≤ 50 °F and wind > 3 mph).

20 °F at 15 mph → ~6 °F.

Frostbite risk?

Lower wind chill speeds up heat loss and frostbite.
