I’ve posted this before, but anybody looking for current water temps on Cozumel can very easily find it at two different sources
Sea water temperature Cozumel today. Quintana Roo Mexico North America.
And
NDBC - Station 42056 Recent Data
Both offer current real time readings. The former site gives water temps at Cozumel. The latter, the NOAA Bouy readings, including water temps, air temps, wind speed, and wave data, is directly from the NOAA Bouy 42056, located 120 nm ESE of Cozumel.
Save one or both of those links, or maybe Christi can give links. Don’t make her do the work over and over when it’s easy for you to check.
