The Wind Chill Calculator calculates how cold it feels by combining air temperature and wind speed. This Wind Chill Calculator applies the standard meteorological formula to calculate the result from your inputs. Conditions change rapidly — check an official forecast for current and forecast data.

The formula behind this calculator: Uses the NWS wind chill formula, which factors in temperature and wind speed in mph. As a practical example: 20°F with a 20 mph wind produces a wind chill of about 4°F. All results are calculated instantly in your browser — no data is stored or transmitted.

Wind Chill Calculator FAQ

What does the Wind Chill Calculator calculate?

Calculates how cold it feels by combining air temperature and wind speed.

Why does the feels-like temperature differ from the actual temperature?

Heat index (humidity effect) and wind chill (wind effect) calculate how temperature feels to the human body, not the measured air temperature. High humidity prevents sweat evaporation; wind increases heat loss from skin.

How accurate is this compared to an official forecast?

This calculates a formula-based result from your inputs. Official forecasts use live meteorological data, weather models, and professional analysis.
