What is the wind chill index?

The wind chill index is the temperature your body feels when the air temperature is combined with the wind speed. It is based on the rate of heat loss from exposed skin caused by the effects of wind and cold. As the speed of the wind increases, it can carry heat away from your body much more quickly, causing skin temperature to drop. When there are high winds, serious weather-related health problems are more likely, even when temperatures are only cool.

Wind chill is similar to heat index in that it combines both temperature and wind speed to determine a “real feel” of the temperature. It represents how much heat would be lost from the body. For example, if the temperature is 25°F and the wind speed is 10 mph, the real feel is 15°F. This means that in a temperature of 25°F and a wind speed of 10 mph, the body would lose heat at a rate as if it were actually 15°F without wind.
