After Hurricane Wilma passed through last year in October it was freezing!!! We were there Oct 23-30.
Bring jeans, short sleeve shirts, a light-weight jacket, sweatshirt, and a hat to cover your head and ears. We would wear jeans and t-shirts during the day with a light-weight jacket wrapped around our waists. By dusk, believe me we needed it! Keep the hat and a rain poncho in your travel bag just in case!
