So that's two people who said, "Ride in the morning."
Don't you people have to get HOME from work?
My solution? Give up.

I'm going to mostly stop commuting by bike until I don't feel so beaten down by the heat. You can do lots to help -- water, clothing, go slow, etc. -- but if it ain't working, it ain't working. 105 in this humidity is simply too much for me, so I'm letting go of ego and skipping August.
You can flame me if you want, but it won't make me any hotter.
EDIT: Ahh, I see now that the OP was referring to riding, maybe not to work.
