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 Conception Island
A wall 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 10 km, the nearest 13 km away. The sea is about 26°C in August, its coldest month (3 mm wetsuit), and 30°C in March, its warmest (rash vest or 1 to 2 mm). The town to stay in is Mahe.

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 about 25 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.
