Question for you down south guys

What weight oil do you guys run down south? I currently live in PA, but I will be in Florida all summer and I was wondering what you guys ran in the south. Any info is appreciated.

I use 10W40 in my Jeeps when it's hot, even though they suggest 10W30 for the '04 WJs 4.7L V8. We've had it since new and with 88,000+ miles on it there's never been an issue. The '97 ZJs 5.2L V8 has 177,000+ miles on it. 10W40 is fine for Tenn. summers (High 90's), but I don't know about Fla. heat. Maybe someone will chime in with some experience.
