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 Merlo Reef
A pinnacle and reef dive. It goes down to 20 m. You get in from a boat. It suits experienced divers only, as a dive guide states it. The coast faces E: swell from the E reaches it, and wind from the W 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 25°C in February, its coldest month (3 mm wetsuit), and 32°C in August, its warmest (rash vest or 1 to 2 mm). No town nearby. Nearest beds: Port Sudan, 138 km. Nearest airport: Port Sudan New International Airport (PZU), 158 km. Within 5 km we also list 1 dive site.
