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 Carysfort Reef
A reef dive. It goes down to 24 m. You get in from a boat. It suits Advanced divers and up, as a dive guide states it. The coast faces SE: swell from the SE reaches it, and wind from the NW blows out to sea. No dive centre within 10 km, the nearest 18 km away. The sea is about 25°C in January, its coldest month (3 mm wetsuit), and 30°C in July, its warmest (rash vest or 1 to 2 mm). The town to stay in is Key Largo.
