I kind of like hot vs. cool - in 80s and 90s even 100. We are having a two week spell of 90s. Did 2 33 mi low 90 rides this week. Just need to keep hydrated and out of direct sun as much as possible.
Since it is so warm, I am going to do some more night rides. It can ride the bike paths (hundreds of miles around here) with nobody else sharing.
Have you considered night rides? You just need a decent head and tail light,.
