HOT! Expect humidity and heat. Imagine being in a toaster oven (for you coming from the north). It will occasionally cool off with a rain shower in the middle of the day, but then the humidity kicks back in.
Shorts and lightweight fabrics. It is Florida so most public places keep the AC running at 60 degrees. I recommend a jacket just in case (but that's just me)
We have lots of different bugs (lil lizards, love bugs, mosquitos, and other various flying things)
