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 Ruins of Old Breakwater

A reef dive. It goes down to 10 m. You get in from a boat. It suits Advanced divers and up, 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 10 km, the nearest 25 km away. The sea is about 5°C in February, its coldest month (drysuit), and 19°C in August, its warmest (7 mm wetsuit and hood). For Advanced divers the best months are usually May, June, July and August, with about 7 good days in 7; in January, about 5. From the weather of past years. The town to stay in is Salisbury. Within 5 km we also list 1 surf spot and 7 dive sites.

What you might see

Too few open records near this site to list its animals. Ask a dive centre what you are likely to see.

This week: visibility under 5 m, clearer than usual (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.

The current and the life no free forecast gives. Ask a dive centre before you book.
