Well, personally I will welcome cooler fall weather--the heat and humidity here are starting to get to me. The only nice thing I can think of about the hot summer weather is that one can swim outside. It's more fun to run, bike, hike etc. when it's nice and crisp rather than hot, sticky and generally icky--fall is my favorite season as far as weather goes. Not to mention (for hiking especially) that the mosquitoes and other bugs are not nearly as bad when it starts to cool off!!
