I live in Florida, so it's hot but I LOVE our summers. We get warm mornings, afternoon thunderstorms, and warm evenings with lightning all through the sky, it is so beautiful. I like also how nobody at the beach is modest or worried about looks (I'm not in Miami) so you see all types in swimsuits.
So summer is my favorite mostly because of the rain, but I do like the beach.
ETA I also like the longer days and shorter nights.
