Best places to dive with Reef manta ray

The Hanifaru Bay signature species. The southwest monsoon (roughly May to December) funnels plankton into the bay and feeding aggregations peak June to November, strongest August to October around the new and full moons, with up to 247 mantas documented in one event. The northeast monsoon (January to March) is quiet. Reef mantas are also seen year-round at Baa's cleaning stations, but the mass aggregation is monsoon-driven.

The main scuba draw at Manta Bowl in Ticao Pass, one of the largest reef-manta aggregations in the Philippines — 280+ individuals identified by LAMAVE. Present year-round at the cleaning stations, most reliable roughly December to May. Requires the offshore Manta Bowl dive.

Reef mantas also visit the pinnacles alongside the larger oceanic mantas, most often Feb-April.

Tourism Fiji identifies May–October as Fiji’s manta season; local daily presence still varies.

Reef mantas use Malé aggregation and cleaning sites year-round, but site choice must follow the monsoon. Southwest-monsoon productivity favours eastern atoll sides; northeast flow shifts productive water west. Peak coding reflects documented North Malé Manta Point use from May to October, not a guarantee across both atolls.

Resident year-round at both Manta Bay and Manta Point. A photo-ID study identified 624 individuals from 5,913 sightings between January 2012 and April 2018, with 82% of individuals re-sighted more than once. Manta Point is the cleaning and courtship site — courtship peaked in April and May, with sightings roughly doubling in May. Manta Bay is a foraging ground used heavily by juvenile males. Manta Point is regularly cancelled in swell, so the animals are more reliable than the dive.

Cleans and feeds at German Channel year-round, peaking with the plankton roughly November–April; feeding aggregations of dozens are possible.

Peak season is December-March at cleaning stations like Manta Sandy and Manta Ridge. Present year-round but far less reliably during the June-September wet season.

Seen year-round around Lady Elliot, with larger aggregations reported during winter.

The signature animal of Tofo. Reef mantas are present year-round at Manta Reef's cleaning stations; sources report bigger aggregations (20+ at a time recorded) leaning to the cooler, plankton-rich months around October-January. Coded reliable all year rather than a single sharp peak.

Reliable year-round at Manta Point's cleaning and feeding stations, Nusa Penida; feeding aggregations are more common in the cooler months (roughly June-October).

Reef mantas are the signature animal at Sangalaki. Survey work logged 846 encounters over 111 dives and photo-identified 123 individuals at Manta Parade and Mountain Coral, described as the only known reef manta cleaning stations in east Borneo; feeding aggregations of up to 42 rays have been recorded, mean about 10. About a third of identified females were pregnant or carried fresh mating scars. Feeding is plankton-driven rather than calendar-driven, so no month is a guarantee. The published survey effort ran October to December across 2017-2019, so year-round presence rests partly on operator reports. The ISRA names the actionable driver: plankton accumulates in the current line on rising (westward) tides, strongest around new and full moon, so tide and moon phase matter more than which month you come.

Present in Komodo year-round, but where they are changes with the monsoon. A photo-ID study of 1,085 individuals (2013-2018) found peak abundance at the central cleaning stations — Karang Makassar and Mawan — from November to April on the northwest monsoon, with the lowest counts in August-September. At Manta Alley in the south the pattern inverts: peak May to October on southeast monsoon upwelling. Animals move between the two, roughly 35km apart. Park-wide the season is therefore close to flat, which is why no single peak is coded — pick the site to match the month, not the other way round. Densest aggregations reported at central stations are 10-20+ individuals in January-February. June-September at the central sites still produces individual mantas, just not the large aggregations.

Reef mantas use Kona's coast year-round, particularly the artificial-light feeding stations. Nightly attendance varies and no month is assured.

Maa Kandu operators report reef mantas at the cleaning station through both monsoons. An Addu-specific research series supporting a peak month was not located, so all months remain occasional rather than resident or peak.

Mantas follow the down-current, plankton-rich side: western Ari is favoured in the northeast monsoon and eastern Ari in the southwest monsoon. No single site is reliable all year.

Possible throughout the operating year; no unsupported monthly peak is applied.

Genuinely unreliable here. Manta Point is named for occasional sightings when the water is plankton-rich in the wet season (roughly December-March), but mantas should not be a reason to choose the Gilis.

Occasional at 8 Mile Rock, sometimes circling divers on the safety stop. Irregular; no reliable season documented here.

Reported over the shallow coral at Wrasse Strip and Navigator's Lane, and along The Runway. Operator and agent listings say only 'manta ray', so the split between reef manta and the oceanic species is not confirmed for this atoll; coded as reef manta on the basis of the shallow-reef cleaning-station context.

Manta and eagle rays cross Monad Shoal; slightly more likely in the plankton-rich November–January months.

Possible year-round near Coral Bay; no guaranteed monthly peak is coded.

Possible throughout the operating year; no unsupported monthly peak is applied.

Occasional at the Cod Hole and Lighthouse Bommie; reported at cleaning stations and in passing rather than reliably resident. No strong single-month peak documented for the Ribbon Reefs.

Koh Bon and Koh Tachai are the main manta sites, with cleaning stations that reef mantas visit most often in the dry season; also seen at Richelieu Rock. Reported roughly January-May. Not guaranteed on any single dive.

Occasional at exposed sites such as Hin Kong, most likely in the February-April pelagic window; never reliable at the Surin island reefs.

Turn up mainly April–May during plankton blooms, often at current-swept sites like Washing Machine; not present on every trip.

Listed by park management among the threatened species present, and mobula rays are recorded in the park. Operator claims of a November-May manta season rest on no published sighting data, so mantas are coded rare year-round. Apo Reef is not a manta destination.

Manta Cove on Atauro takes its name from mantas, but sightings are not reliable and no published seasonality was found. Treat any manta encounter here as a bonus rather than a reason to book. Coded rare because the only sources are operator site descriptions.

Possible in suitable habitat; no unsupported monthly peak is applied.

Possible in the region; no unsupported monthly peak is applied.

Mantas are possible offshore but are not a reliable Niʻihau dive feature.

Possible in the region; no unsupported monthly peak is applied.

Reef mantas occur around Maui but are not a reliable feature of routine Molokini or Lānaʻi dives.

Possible in suitable habitat; no unsupported monthly peak is applied.

Mantas are only an occasional visitor at Wakatobi and are not a reliable draw; this is a reef and macro destination rather than a manta one.
