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 Observatory Rock
A reef dive. It goes down to 26 m. You get in from a boat. It suits experienced divers only, as a dive guide states it. The coast faces SW: swell from the SW reaches it, and wind from the NE 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 7°C in January, its coldest month (drysuit), and 13°C in July, its warmest (7 mm semi-dry or a drysuit). No town nearby. Nearest place to stay we found: Queen Charlotte Lodge, Area D (Graham Island), 4 km. Nearest beds: Masset, 28 km. Nearest airport: Masset Airport (ZMT), 30 km. Within 5 km we also list 1 dive site.
