Wind map
Monday, January 1st, 2007
This map from the wunderground.com weather web site shows the wind direction and speed.
I read somewhere that, once a bicyclist is up to cruising speed, 90% of the energy spent is just to overcome wind resistance. So when the wind is blowing that much harder in your face, well, that makes it slower going for bicyclists. (For automobiles, you will notice, if you keep track of your fuel efficiency, that your gas mileage will dip when it’s very windy out.)
