Note: Wind Chill Temperature is only defined for temperatures at or below 50 degrees F and wind speeds above 3 mph.

The wind chill factor, which only affects humans and animals, causes the air to feel colder than it really is. This helps us to understand how cold it feels outside! Moving air carries heat away from the body more effectively than air that is not moving. If there is no wind, the heat radiating from a person's body will stay near the body and warm the air around it. Therefore, the wind chill is simply a means of describing the effect of the movement of air on the heat loss of a person's body.

Note: When wind speeds are 3 mph or less, the above formulas will give you a wind chill that is higher than the actual temperature. When wind velocities are near zero and you are standing still, your body heat warms the air near your body. This warm air near your body provides some insulation from the colder environment. As a result, it may actually feel warmer than the actual temperature.
