Wind chill (often popularly called the wind chill factor) is the felt air temperature on exposed skin due to wind. The wind chill temperature is never higher than the air temperature, and the windchill is undefined at higher temperatures (above 10 °C ). Humidity on the skin can result in a higher perceived air temperature, which is accurately termed the heat index (or humidex), and is used instead; note however that heat index figures do not include any reference to wind speed.

Famous quotes containing the words wind and/or chill:
“To be shelterless and alone in the open country, hearing the wind moan and watching for day through the whole long weary night; to listen to the falling rain, and crouch for warmth beneath the lee of some old barn or rick, or in the hollow of a tree; are dismal things—but not so dismal as the wandering up and down where shelter is, and beds and sleepers are by thousands; a houseless rejected creature.”
—Charles Dickens (1812–1870)
“The woman was old and ragged and gray
And bent with the chill of the Winter’s day.”
—Mary Dow Brine (1816–1913)
