Summer running tips?

I officially don't like humidity when it comes to running. Went out this evening; it wasn't hot, but it was muggy. And I had all those overheating problems that I had back on the treadmill, and had to cut things short. Yuck!

Anyone have tips for keeping up running during hot & muggy summer weather? I fear the answer is going to be "get up at 5 a.m. and go running then."
