I wouldn't want to live in a place without proper seasons. I could definitely relate to hating summer then. I'm from the north so I look forward to summer, but I also don't tolerate heat all that well. Right now I'm in a warmer country and the summers here do get to friggin hot, I complain about them all the time. 90 F is the typical high but it's been up to 100 which is just too freaking much, especially in the city where all the buildings and the pavement just radiate even more heat at you.
The people saying winter is the worst have a point but it's hard to compare, because it's not really the cold that's the bad part IMO. For me it's the darkness.
