It used to be summer, because I love that heat, but could do without the horrific humidity here in Kansas (and our state bird, the mosquito). Now it's fall. It's still fairly warm (warmer than spring, when we keep dropping back into winter temps) and then there's all the pretty colors as the trees change. You know, when they do actually change when the weather was normal. Last few years have literally gone from green to brown in less than a day....
