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 Koh Bon Pinnacle

A pinnacle dive. It goes down to 40 m. You get in from a liveaboard. It suits experienced divers only, as a dive guide states it. The coast faces N: swell from the N reaches it, and wind from the S 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 29°C in January, its coldest month (rash vest or 1 to 2 mm), and 30°C in March, its warmest (rash vest or 1 to 2 mm). The town to stay in is Khao Lak.

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 20 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.

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