The water temp today at Key Largo is 81° F. I seriously doubt he wore any wetsuit.
Lots of us cold and stinging critter intolerant folks are always in a wetsuit. I am always covered, head to toe. In 80-85 F I'm in a 2.5mm wetsuit with a lycra hood. I'm far more comfortable temperature wise and much better protected from random stinging critters and critter-parts floating around in the ocean. Get a random jelly fish stinging cell up your board shorts and you too will always be in a wetsuit. So wearing a wetsuit in 81 F is not at all unusual here in South Florida.
I've seen plenty of people in CZM wear a wetsuit in 85° water. I don't understand it, but they do.
Exactly. Same for South Florida/Key Largo.
