There is no effect on either the old or new formula if wind speeds are under 3 MPH statute, while there is no effect on the old system until the are near 5 MPH statute, or the equivalent in other speed designations. The greatest range of wind speeds for effect is from 5 to 50 MPH statute. While the change in the wind chill factor above 50 MPH statute 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.
