A named reef from the chart, not a dive site anyone has told us about. It may be a great dive or a sandbar at low tide. If you dive it, log the dive here so the crew knows.

Busiest Jan, Mar.

From 9,064 logged sightings — when divers are in the water, which is not quite the same as when visibility is best.

Moon and tides

Waning gibbous

70% lit · day 20 of the lunar month

Neap tides

Neap tides — the smallest range of the month, so the weakest currents. Easy conditions and usually the clearest water, though a drift site may barely drift.

New 10 Oct Full 26 Oct

Phase computed here, not fetched. This is the spring/neap cycle, which sets how hard the water moves — not a tide table: no free source publishes high and low water for Southeast Asian reefs, and the range peaks a day or two after the moon does, by an amount that varies with the coast. For times on the day, ask the operator.

Times marked ~ are estimated from straight-line distance and will be roughly right at best. The road legs are the ones Google Maps answers properly; it will not plan the ferry or the dive boat at all. A dive site's coordinates put a pin in open water, so the map link drops you on the site, not on a jetty.
