I would bring a light jacket, but if you are from the northeast. It could be warm for you, it's 42 now and cloudy. Yesterday only got to 55, 70's and in the 50's would be warm for me. It's to me capri and short weather down there now. I would also bring a light sweatshirt with me.
This past weekend our best friends that live down there were in there pool. I guess it was hot, cool front coming in. But still not as cool as it is up here. Have fun, wish I was going!
