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 หินใบ
A reef dive. It goes down to 35 m. You get in from a boat. It suits Advanced divers and up, as a dive guide states it. The coast faces NW: swell from the NW reaches it, and wind from the SE blows out to sea. No dive centre within 10 km, the nearest 17 km away. The sea is about 28°C in January, its coldest month (3 mm wetsuit), and 31°C in May, its warmest (rash vest or 1 to 2 mm). The town to stay in is Koh Tao.

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 15 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.
