Frequently Asked Questions
What is wind chill?
Wind chill is the apparent temperature on exposed skin when cold air and wind combine. It explains why a windy winter day can feel much colder than the thermometer reading.
How is wind chill calculated?
The calculator uses the NOAA/NWS wind chill equation when air temperature is 50 F or lower and wind speed is at least 3 mph. For hot, humid inputs it switches to the heat index formula.
At what wind chill temperature is frostbite dangerous?
Frostbite risk rises quickly below 0 F wind chill. Around -19 to -32 F, exposed skin can be at risk in about 10 minutes, and below -48 F the risk can be under 5 minutes.
What is the difference between wind chill and heat index?
Wind chill estimates cold stress from wind and low temperature, while heat index estimates heat stress from temperature and humidity. They apply to opposite weather conditions.
