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.

About Danger Reefs
A reef dive. It goes down to 18 m. You get in from a boat. It suits Advanced divers and up, as a dive guide states it. The coast faces S: swell from the S reaches it, and wind from the N blows out to sea. No dive centre within 10 km, the nearest 20 km away. The sea is about 7°C in January, its coldest month (drysuit), and 18°C in July, its warmest (7 mm wetsuit and hood). The town to stay in is Ladysmith.
