About Wind Chill
The wind chill temperature tells you how cold it actually feels on your skin when the wind is blowing. As wind increases, it draws heat away from the body faster, causing skin temperature to drop and increasing the risk of frostbite.
The Formula
National Weather Service (US) Formula:
WC = 35.74 + 0.6215*T - 35.75*(V^0.16) + 0.4275*T*(V^0.16)
Constraints
- Temperature must be at or below 50°F (10°C).
- Wind speed must be above 3 mph (4.8 km/h).
FAQ
No. Wind chill only describes the rate of cooling. An inanimate object will
not cool below the actual air temperature, no matter how hard the wind blows. It just reaches
that temperature faster.
Frostbite is the freezing of skin and underlying tissues. At wind chills
below -18°F, frostbite can occur in 30 minutes or less on exposed skin.
