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 Hornby Rock
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 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 9°C in January, its coldest month (drysuit), and 13°C in July, its warmest (7 mm semi-dry or a drysuit). For Advanced divers the best months are usually May, June, July and August, with about 7 good days in 7; in January, November and December, about 3. From the weather of past years. The town to stay in is Ucluelet. Within 5 km we also list 1 dive site.
