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 Angel's Window

A pinnacle dive. It goes down to 32 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 50 km on the map: book a liveaboard or a boat from further off. The sea is about 28°C in August, its coldest month (3 mm wetsuit), and 30°C in April, its warmest (rash vest or 1 to 2 mm). The town to stay in is Siladen. Within 5 km we also list 11 dive sites.
