Season
When this place works
No formal closure. Typhoon risk runs roughly May-Oct and sources disagree on how badly it bites: DAN says avoid Jun-Sep, Divernet calls Mar-Sep the most stable window, and one field account calls the Jul-Dec rainy season mild. Encoded…
Why dive here
What this place is known for
01sharkPelagic thresher sharks
The only destination where pelagic threshers are seen predictably and daily. They come to reef-fish cleaning stations on a seamount plateau; a PLOS ONE study documented 97 cleaning events over 1,230 hours of video across 232 days, with frequency highest in…
02macroMacro and critter subjects
Surprise relative to the headline: Malapascua is sold entirely on threshers, and almost every diver books two or three nights around one dawn dive. The macro on the surrounding reefs is competitive with dedicated Philippine critter destinations. Multiple…
03caveGato Island
Cavern swim-through under the island plus a wall known locally as 'Nudibranch City'. Sea snakes, sleeping whitetip reef sharks, pygmy seahorses. Roughly a 45-minute boat ride.
Marine life
Twelve-month species timelines
Present year-round; the constraint is time of day, not month. Cleaning-station visits decline significantly from morning to evening. Sighting probability on a given dawn dive is high but not…
Courtship display at sunset, roughly a 20-minute window. Reliable to the point of being scheduled.
Chocolate Island is the most consistent site. One field account reports a mating-season concentration in roughly late April to May; this is a single observation and the encoded peak is weakly…
Multiple pygmy species reported around Gato Island and the surrounding sites. Species-level identification in the sources is loose; H. bargibanti is the one consistently named.

Low confidenceSHIPPING CONTESTED. Inshore sites are calm and beginner-friendly; the seamounts carry moderate to strong current. Four sources give four different answers on where the thresher dive actually happens and how deep, which is what drives the…
Entries — boat
Recommended & required
- nitrox — recommended. Consecutive deep dawn dives on the shoal stack up nitrogen fast.

The only sensible format. Getting there is a flight to Cebu, roughly 3.5 hours by road to Maya Port, then a short ferry, so budget a full…

Some Visayas liveaboard itineraries call at Monad Shoal, usually for a single dawn dive. Lower odds than a multi-day land stay, since you…
