In December you might find some storms moving through. It can screw up the shore diving if that's your focus. When the storms come through, most of the dive boats go south - LaPeruse and farther. While the diving's not as great as it is in August, it's still OK. Normally the water clears a day or two after the storm has passed.
Actually, we were thinking about going for Christmas this year, but a lot of the places we like are already booked and the rates are just a tad high. So, we're going to try Cozumel over the Holidays. Never been there. I think we're gonna like it!
