What is the current water temperature in Cozumel and are there any thermoclines this time of year? Third time on the island but first time in Dec. Thanks.

I can answer your questions without being in Cozumel.
Been diving the last 5 days - my temp readings have been 79-81 degrees.
Strongly disagree with the temps not changing that much. From the dead of winter at 77f. (I'd be wearing a full 5mm wetsuit with 3mm vest w/hood underneath).....to 84f.+ (I'd be wearing Body Glove surfer shorts and 2mm vest).
We were there in Dec last year....pretty chilly, no sun for the surface intervals so wore a full 3mm with a vest.
That's a total range of 7F. Compared with the much, much larger range of temperatures here locally (surface water temperatures from 80F down to cold enough to drive a truck on), 7F is hardly any change at all - it's about 1.8% in terms of degree change.*
Sounds like Ohio.
