Where to see Whale Shark Aggregations in 2026

Best months

Difficulty & experience

Best locations

• Ningaloo Reef

  Australia

  primary

  Permit-capped, well-managed snorkel operation timed to the post-coral-spawn plankton bloom.

• Ari Atoll

  Maldives

  primary

  Year-round sightings along the south reef edges with predictable seasonal density.

Sites at these locations

• Manta Point (Madivaru)

  Ari Atoll, Maldives

  Cleaning station on the eastern edge of South Ari Atoll where reef mantas queue at coral bommies in the afternoon. Outside the cleaning windows the site is a relaxed reef dive at 10-14 m; during peak activity it can feel like manta traffic control.

• Ningaloo Whale Shark Encounter

  Ningaloo Reef, Australia

  Snorkel-only encounter with whale sharks that aggregate along Ningaloo Reef from March to August. Spotter planes vector boats onto sharks; you slip in alongside them for a few minutes before they cruise on. Strictly regulated for shark welfare.

• Maamigili Beyru (Whale Shark Point)

  Ari Atoll, Maldives

  Outer reef along the southern edge of Maamigili island, gazetted in 2009 as part of the South Ari Marine Protected Area to safeguard the only known year-round whale shark aggregation in the Indian Ocean. Juvenile sharks 4-8 m long cruise the shallow reef shelf at 5-15 m feeding on copepods, and the South Ari research programme has logged sightings on more than 70% of days. The dive is a drift along the outer wall where the reef drops past 200 m — manta and mobula rays pass on cleaning rotations, eagle rays glide the slope, and grey reef sharks patrol deeper. Operators run a coordinated radio search; snorkellers stay at the surface while scuba divers hold below 5 m. MPA rules cap boat numbers and forbid touching, flash photography, and motorised approach within 20 m.

• Cocklebiddy cave

  Ningaloo Reef, Australia

  Cocklebiddy Cave is a world-renowned, extremely challenging technical cave diving site located in the remote Nullarbor Plain of Western Australia. Known for its extensive underwater passages and pristine geological formations, it attracts experienced technical divers seeking exploration in one of the longest underwater cave systems. The site offers a unique opportunity to witness untouched subterranean environments.

• Tiger Harbour (Fuvahmulah)

  Ari Atoll, Maldives

  A harbour-mouth plateau at the southeast tip of Fuvahmulah, the Maldives' isolated single-island atoll, where the Indian Ocean's largest known resident tiger shark population gathers. Six to eighteen tiger sharks — many individually identified and re-sighted for years — circle a sandy ledge around 8-12 m beside a wall that drops past 60 m, close enough to fill a wide-angle frame in clear water. Divers kneel in a line behind the guide while the dive team works a bait box. The same exposed outer reefs draw pelagic thresher sharks to dawn cleaning stations and schooling scalloped hammerheads from October to April, with oceanic mantas, silvertips, and the occasional whale shark or mola passing through. Currents run hard and the swell is open-ocean.

• Navy Pier Exmouth

  Ningaloo Reef, Australia

  Active naval pier converted into one of the highest-density biomass dive sites in the world. Grouper, wobbegongs, and resident grey nurse sharks shelter under the structure; macro life in the pylons rivals Lembeh. Access controlled by the Australian Defence Force.
