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:
“They are very proper forest houses, the stems of the trees collected together and piled up around a man to keep out wind and rain,—made of living green logs, hanging with moss and lichen, and with the curls and fringes of the yellow birch bark, and dripping with resin, fresh and moist, and redolent of swampy odors, with that sort of vigor and perennialness even about them that toadstools suggest.”
—Henry David Thoreau (1817–1862)
“The woman was old and ragged and gray
And bent with the chill of the Winter’s day.”
—Mary Dow Brine (1816–1913)
