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:
“When the wind carries a cry which is meaningful to human ears, it is simpler to believe the wind shares with us some part of the emotion of Being than that the mysteries of a hurricane’s rising murmur reduce to no more than the random collision of insensate molecules.”
—Norman Mailer (b. 1923)
“Greater glory in the sun,
An evening chill upon the air,
Bid imagination run
Much on the Great Questioner;
What He can question, what if questioned I
Can with a fitting confidence reply.”
—William Butler Yeats (1865–1939)
