Seems like I'm starting to get acclimated to the warmth. Not suffering quite as much as I was before. I'll see later today, though - not getting out until 9am and should be out through 1pm or so; forecast calls for low 90s again.
I'm betting it's just time x degrees above some threshold with some sort of decay function. Acclimation doesn't have much if anything to do with how hard you work. There is no cardiovascular adaptation other than expanded plasma volume.
