Maldives whale shark tours. Year-round, in one place.

Whale sharks are resident in the South Ari Marine Protected Area year-round — they do not migrate seasonally. This is the critical fact most competitor guides get wrong. Unlike manta rays at Hanifaru Bay (which have a clear May-November aggregation), juvenile whale sharks are present in South Ari every month of the year. Sightings are slightly more reliable in the dry season (December-April) because of better surface visibility, but operators see whale sharks on 70-90% of tours across all 12 months.

The South Ari Marine Protected Area (SAMPA), declared in 2009, covers the southern rim of South Ari Atoll, roughly 14 km long from Maamigili in the west to Dhigurah in the east. This is the only documented resident aggregation of whale sharks in the world — everywhere else (Belize, Galapagos, Ningaloo) has seasonal migrations. Boats launch from the inhabited islands of Maamigili (close to the airport), Dhigurah, and from South Ari resort islands.

Both. Unlike Hanifaru Bay (manta feeding aggregation) where scuba has been prohibited since 2012, the South Ari MPA allows both scuba and snorkel encounters. Whale sharks in South Ari cruise the reef shelf at 5-15 m depth — well within snorkel range. Scuba divers see them on drift dives along the outer reef wall. Most day tours offer snorkel-only programmes; dive resorts like Constance Moofushi, Vilamendhoo and Lily Beach run scuba-specific whale shark outings.

Guesthouse-based snorkel day tours from Maafushi or Dhigurah run USD 80-150 per person including boat, snorkel gear and lunch. Resort-based snorkel excursions run USD 120-250. Scuba dives with whale shark chance (part of a 2-tank boat dive from a South Ari resort) run USD 130-200 per dive including tanks. Liveaboards doing dedicated whale shark itineraries charge USD 2,500-4,000 per week. Private boat charters for families start around USD 800 per half-day.

South Ari resorts have the proximity advantage — most are inside or adjacent to the MPA and can get to known cruising sites in 15-30 minutes. Constance Moofushi, Vilamendhoo Island Resort, Angsana Velavaru (technically Dhaalu but within range), Lily Beach, Sun Island, and Conrad Maldives Rangali Island all offer dedicated whale shark excursions. For guesthouse travellers, Dhigurah is the best local island — whale shark sightings are almost daily from its southern reef edge.

The SAMPA code of conduct requires a 3-metre minimum distance from the animal — no touching, no chasing, no flash photography. Operators enforce this; the Maldives Whale Shark Research Programme monitors compliance. Whale sharks are typically 5-10 metres long so they appear very close even at the regulation distance. Swim parallel to the animal, never head-on, and stay out of its projected path. Boats must approach at dead-slow speed within 200 m.

The South Ari MPA is one of the best-regulated whale-shark encounter sites globally. The 3 m distance rule, operator licensing, boat speed limits, and fin-touching prohibition are enforced by the Maldives Marine Research Institute. The Maldives Whale Shark Research Programme (MWSRP), a UK-registered charity based on-site, photographs and catalogues individual whale sharks via spot patterns — 500+ individuals identified since 2006, providing one of the longest-running resident-population datasets in the world. Choosing a licensed operator who respects the code is both ethical and supports the research.

Juvenile whale sharks in South Ari typically cruise at 5-15 m during daytime, occasionally surfacing. They make deeper dives at night to forage (recorded down to 1,000+ m on satellite-tagged individuals), but the daytime behaviour that makes South Ari unique is this shallow shelf-cruising. This is why snorkel encounters work so well here — you don't need scuba gear to see them, and scuba divers don't need to go deep.
