Wind Chill Table

Often cold temperatures can feel much colder based on the speed of the wind. That effect is called the wind chill factor. This table has factors of wind speed in miles per hour (MPH) in the vertical columns, getting progressively faster from top to bottom of the chart, and temperature in degrees Fahrenheit in the rows, getting progressively colder from left to right. Keep in mind that wind speeds of under 5 MPH have a negligible effect on the wind chill calculation. You can also use our wind chill calculator if you wish to see a wind speed or temperature not shown here.

The greatest range of wind speeds for effect is from 5 to 50 MPH. While the change in the wind chill factor above 50 MPH is not really negligible, it is minimal. That wind effect tends to evaporate the moisture from the air and cause the enhanced cooling effect to humans, plants and animals, just as a breeze does on a hot summer day. Great care should be taken to avoid conditions conducive to low temperatures, with or without wind chill factors. However, with a wind chill effect, the possibility of frostbite is greatly increased.
