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 18°C in February, its coldest month (7 mm wetsuit and hood), and 30°C in July, its warmest (rash vest or 1 to 2 mm). The town to stay in is Mexico Beach. Within 5 km we also list 1 dive site.
