What's the water temp usually like in Cozumel mid-June?
I'm trying to figure out if I want to buy a lycra skin, a 1mm full or what.
I'm big (6'2", 260) and insulated enough that I've been OK with just trunks and a rash guard for a couple of dives at a time in 78-80 degree water, like in Coz this past March 12. I'm just not sure that I'll be good to go without any thermal protection for over 5 straight days of diving.
