What is Wind Chill?

The wind chill temperature is not the actual air temperature, it is a “feels like” temperature when one factors in cold temperatures AND wind speeds. Increasing winds will accelerate the amount of heat lost by the body via exposed skin, driving down the body temperature. Animals are also affected by wind chill.

The only effect wind chill has on inanimate objects, such as car radiators and water pipes, is to shorten the amount of time for the object to cool. The inanimate object will not cool below the actual air temperature. For example, if the temperature outside is -5°F and the wind chill temperature is -31°F, then your car's radiator will not drop lower than -5°F.

The wind chill chart below was developed based on joint U.S.-Canadian research. The chart includes a frostbite indicator, showing the points where temperature, wind speed and exposure time will produce frostbite on humans. Each shaded area shows how long a person can be exposed before frostbite develops.

Note: Wind chill temperature is only defined for temperatures at or below 50°F and wind speeds above 3 mph. Bright sunshine may increase the wind chill temperature by 10 to 18°F.


Staying Safe

Here are a few tips to staying safe during times of cold weather:

  • First and foremost, minimize your time outside. Postpone any outdoor activities if at all possible.
  • Cover all exposed areas of skin, including your face, to avoid frostbite.
  • Wear multiple layers of loose fitting clothing, as the air pockets between the layers provides excellent insulation.
  • Wear mittens instead of gloves as they allow your hands to stay warmer for longer.
