Its December and Ambergris Caye has had a week of cool weather. The Caribbean waters at the Barrier Reef have dropped to 78f./26c. still warm by most standards but chilly for the local divemasters but good for the corals.

Brrr . . . need my hood at that temp.

January's starting temperatures are 79-80f.
The visibility was 100'+ yesterday. The coolness of the water doesn't allow some plankton growth that effects visibility.

January 15th and the average water temp has been 81F. or 27. Degrees Celsius.
Rarely is there a thermocline, due to the tides and turbulence.

Woa! Spring has Sprung!
Today’s water temperature is 82F. or 27.7 Degrees Celsius
