If going slow enough like in a climb, the headwinds doesn't feel as bad and they do help to cool off. Ofc, a strong tail wind would be a lot better to cool you off and also give a bit of push in a climb!
I guess another paradoxical effect in hot weather is riding up the mountains with at least 2000 ft altitude. The air is a bit thinner up there but the lower temperatures will help make the climb a lot more comfortable.
