Monad Shoal is the most reliable place in the world to see pelagic thresher sharks. They rise from deep water at dawn to be cleaned by wrasse on the plateau at roughly 25 m. Dives start in darkness and divers hold position behind a rope line — approaching the cleaning stations drives the sharks off. Cold thermoclines and an early start make this a dive for people comfortable at depth in low light.

Twenty-five minutes by boat from Malapascua, departing around 05:00.

Forecast heights against mean sea level. Real tides in a bay, a harbour or over a flat can differ — check an official tide table before you get in.

Only wave height and wind are scored, because those are what close a boat ramp or a shore entry. Water temperature is reported and never scored: 12°C is an ordinary dive in a drysuit and punishing in a 3 mm, and a number that cannot see your suit has no business marking it down. Stars do not decide whether you get in — you and your guide do, on the day.
