Best places to dive with Grey reef shark

The headline species. The South Pass holds a resident aggregation commonly counted at 300-700 grey reef sharks year-round. Densities peak around the June-July full moon when the sharks feed on spawning groupers. Present at both passes; sightings are reliable but exact numbers vary with tide and season.

Resident around current-swept thilas such as Fish Head and Maaya Thila; numbers and proximity change with tide and boat traffic.

Resident on Baa's outer reefs and channels year-round, with a grey reef shark nursery at Anga Faru. Sightings favour current-swept channel and thila dives rather than any season.

Regular on the outer walls and off the drop-off at Manuk, Hatta and Koon. Numbers are moderate — this is not a shark-protected area like Raja Ampat, and the surrounding waters are fished.

Recorded at the Maratua channel and Kakaban's Barracuda Point, usually in current and usually as singles or small groups — not the densities of Indonesia's shark-focused regions.

Grey reef sharks are among the more reliable large animals here, patrolling the deeper walls of both pinnacles.

Concentrated on the northern seamounts — Castle Rock and Crystal Rock, where operators report them patrolling daily — rather than spread through the park. Also reported at Langkoi Rock in the far south. Year-round; no seasonal pattern found in the sources reviewed. Best seen hooked in on the current-facing side, which is why this is an advanced-site animal.

Reported on most wall dives, particularly D'Wall, Gorgonian Forest and The Runway. The most consistently seen shark on the atoll.

Resident around current-fed channel mouths and pinnacles. Numbers and proximity depend on tide and diver position.

Resident at Blue Corner, Ulong and Peleliu; numbers and activity peak March–May around the full and new moons.

Resident and commonly seen in the passes and along outer reef walls, especially in current at sites like Dynamite Pass. Year-round; not seasonal.

The most reliable shark here — grey reef sharks appear on nearly every dive, often in groups of several, patrolling the walls and drift sites like Washing Machine and Amos Rock.

Resident on the channel mouths, with the official Miyaru description emphasizing sightings during northeast-monsoon incoming flow. Strong current improves the viewing opportunity but makes the dives harder.

Reported at current-facing channels, especially Kuda Kandu and Maa Kandu. Numbers depend on current and should not be inferred from a site nickname.

Patrol the current-swept pinnacles, notably Kal's Dream and Sharks Galore off Pura, alongside whitetip reef sharks.

Recorded at Apo Reef by Global FinPrint surveys, usually along the deeper wall sections such as Binangaan Drop-off rather than on the plateau. Regular but not a given on any single dive — this is a reef rebuilding its shark numbers, not a grey-reef aggregation site.

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

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

Reported on outer reefs throughout the operating year. No defensible month-specific peak was found.

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

Recorded by non-baited cameras and on outer reefs. Current and site choice matter more than a verified calendar.

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

Seen in the blue at Shark Cave, Black Rock and the Banks. Numbers are modest by Indo-Pacific standards; this is a fished archipelago and reef shark encounters are singles and pairs rather than schools.

An occasional wall and blue-water encounter in the north, chiefly at Tiran. Grey reef sharks are far more reliable on Egypt's southern offshore reefs (the Brothers, Daedalus) than around Sharm.

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

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

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

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

More common at South Point and the deeper wall (Sipadan closed in November).

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

Reported at Koh Torinla and exposed reef edges; less frequently seen than the shallow-reef blacktips.

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

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

Occasional around the wrecks and lagoon passes; not the reason to come here.

Occasionally seen in the blue off the more exposed points such as Sachiko's, but far less reliable than the reef whitetips and blacktips.

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

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

An occasional exposed-site sighting rather than a routine encounter; Batee Tokong and Shark Plateau offer the better chance.

Reported occasionally on Vava'u reefs but the least commonly seen of the three reef sharks here.
