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.

No dive centre within 10 km, the nearest 24 km away. The sea is about 9°C in March, its coldest month (drysuit), and 17°C in July, its warmest (7 mm wetsuit and hood).
