Coron Bay, fed by the tropical tides of the South China Sea, offers year-round water temperatures ranging from 28 to 30 degrees. What this means to our diving guests is obvious: the only body insulation needed in these bathtub-warm waters is a skin-thin 3 to 5 millimeter tropical wetsuit!

Dive visibility in and around Coron Bay typically varies according to tidal strength, but generally ranges between 7 and 30 meters. Maximum water clarity is generally encountered during a 1/4 to 3/4 moon phase; During a full or new moon, water visibility is somewhat reduced but never enough to spoil a dive.

Dive destinations located close to the open ocean waters (such as the Nanshin Maru Wreck off of the coast of Black Island and Cathedral Cave at the southern tip of Coron Island) and land-locked bodies of water (such as the geothermal waters of Barracuda Lake) have the best dive visibility – typically 20-meters and more.

Since the varying phases of the moon play such an important role in tidal strength and underwater visibility, we have included a 7-day moon-phase forcast (shown below) for the interest and guidance of our scuba diving guests and site visitors.

Moon Phase Forecast is currently under construction.
