Local clock times; heights about mean sea level. On open coasts the times are usually within a quarter of an hour; in bays, estuaries and on the Gulf of Mexico they can be an hour or more out. Slack water, the safest time to dive where there is current, is about half an hour either side of each high and low.

The sea is about 29°C in January, its coldest month (rash vest or 1 to 2 mm), and 30°C in April, its warmest (rash vest or 1 to 2 mm). No town nearby.
