Guidance
Enter temperature and wind speed to see guidance.
General information only, not medical advice. If exposed skin turns pale, hard or numb, get indoors and warm up slowly; seek medical help for severe cold injury.
How to use
- Choose metric or imperial units.
- Enter the current air temperature and wind speed.
- Read the feels like temperature and follow the guidance for your frostbite risk level.
Note: The formula is designed for temperatures at or below 10°C (50°F) and wind speeds above 5 km/h (3 mph). Calm wind gives a wind chill equal to the air temperature. This is an estimate.
Tips
- Dress in layers and cover exposed skin when the wind chill is low.
- Wet clothing loses heat fast — change into dry clothes when possible.
- Children and elderly people lose body heat faster and need shorter outdoor time.
- Watch for white or gray patches on skin — an early sign of frostbite.
