A question about water temperature in Key Largo and Fort Lauderdale

Heya, I am hoping that South Floridians or anyone could to answer these questions:

Me and my buddy are going to dive in Key Largo and Fort Lauderdale during the first week of March (March 1st - 3rd) and we were wondering what the water temperature usually is at that time?

Also, how deep is the thermocline - and how severe is the temperature drop? We only plan to dive up to 75 feet as our max depth...

the reason why we're asking is that we're trying to figure out what's the correct wetsuit to get... :06:

Thanks in advance!

The water is about 75 degrees in Key Largo during March. (http://www.nodc.noaa.gov/dsdt/cwtg/).

March is a good time to go, before the threat of hurricanes which I guess are going to pound us again next season. For the latest dive conditions you can check the National Weather Service buoy reports at www.nws.fsu.edu/buoy/fl.html. But the water is usally clear as a bell and never below 70 degrees even in the dead of winter. Spring should be wonderful and warm.

As to the other part of your question

The thermocline is much deeper than recreational limits. So unless you're into deep technical diving, it's not an issue.
