Weather Research

To help us understand better what cloths we need to pack, we use two tools. First the National Weather Service website which is a site great to find temperature trends and averages. Then we used the following formula to calculate our wind chill on our bikes:

Windchill (ºF) = 35.74 + 0.6215T - 35.75(V^0.16) + 0.4275T(V^0.16)

Where: T = Air Temperature (F)
V = Wind Speed (mph)
^ = raised to a power (exponential)

Windchill Temperature is only defined for temperatures at or below 50 degrees F and wind speeds above 3 mph. Bright sunshine may increase the wind chill temperature by 10 to 18 degrees F.

Here is a calculator using that formula to calculate your wind chill:
