June Weather Averages for Cozumel, Mexico
Most travelers to Cozumel have been comfortable in a diving in a skin, but others have felt cold and needed to wear a 3 ml wetsuit. So if you're one of those divers that are on the cold side, you might want to bring your 3 ml.
Also keep in mind if you signed up for the whale shark excursion, you'll need a 3mil or shorty, if not they will make you where a life jacket.
