What is the average water temperature in the bahamas at the end of april-beginning of may?

The water temperature is several degrees colder on average than the air temperature. But water draws heat out of the body more easily, so it seems colder than it actually is. The chart below shows the average weather for the Bahamas by month. Looks like you should be fine. If I can go swimming in Cancun during February, you shouldn't have a problem with the Bahamas in late April to early May.  more
