It's hot down here. I don't bother to look at the temperature because it would go to my head and I'd stay indoors all day. I know it's over 100°F because even as I ride at 45mph, the air warms my skin. The effect is like that of a convection oven. It's almost the opposite of wind-chill. Unfortunately the term "windburn" describes a phenomenon that is unrelated to heat. What can we call this then?
