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 Jeffrey 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 10 km, the nearest 22 km away. The sea is about 7°C in January, its coldest month (drysuit), and 18°C in July, its warmest (7 mm wetsuit and hood). The town to stay in is Parksville.

This week: visibility about 10 m, about usual for the month (satellite plankton reading, 24 Oct). Estimated from the month's typical visibility and this week's satellite chlorophyll against the site's normal; heavy rain before a dive can still muddy it.
