Quick Answer
The best whale shark encounters are in the Maldives’ South Ari Atoll (year-round), Ningaloo Reef in Australia (March–July), Isla Mujeres in Mexico (June–September) and Donsol in the Philippines. Here are 10, with seasons and an honest note on which sites feed the animals.
Whale sharks are the largest fish in the ocean and entirely harmless — filter feeders that tolerate swimmers. Encounters are seasonal and, increasingly, regulated. These 10 destinations are the most reliable, with the ethics of each set out plainly.
10 Best Whale Shark Destinations
1. South Ari Atoll, Maldives
Best months: Jan–Mar · 27–28°C days · some rain (ERA5 climate data)
One of the few places with year-round resident whale sharks, snorkelled rather than dived, in warm shallow water.
2. Komodo & Flores, Indonesia
Best months: Jul–Sep · 23–33°C days · rainy (ERA5 climate data)
Whale sharks gather around fishing platforms in Saleh Bay, often at dawn, alongside Komodo’s manta and reef diving.
3. The Similan Islands, Thailand
Best months: Dec–Feb · 22–32°C days · dry (ERA5 climate data)
Seasonal sightings on liveaboards between November and May, particularly around Richelieu Rock.
4. Isla Mujeres & Holbox, Mexico
Best months: Dec–Feb · 7–23°C days · dry (ERA5 climate data)
The largest known aggregation on earth gathers off the Yucatán between roughly June and September — snorkelling only, with strict operator rules.
5. Ningaloo Reef, Australia
The most tightly regulated encounter anywhere, running roughly March to July, with spotter planes and small group sizes.
6. Donsol & Oslob, Philippines
Best months: Jan–Mar · 23–30°C days · some rain (ERA5 climate data)
Donsol’s encounters are with wild, unfed sharks; Oslob’s are provisioned by feeding, which many conservationists object to — choose accordingly.
7. Mafia Island, Tanzania
Whale sharks feed in shallow water from around October to March, in one of the least crowded settings.
8. Cenderawasih Bay, Indonesia
Best months: Jul–Sep · 23–33°C days · rainy (ERA5 climate data)
Remote West Papua, where whale sharks associate with fishing platforms year-round — reached by liveaboard.
9. Utila, Honduras
Caribbean encounters alongside some of the cheapest dive certification in the world.
10. Djibouti
Juvenile whale sharks in the Gulf of Tadjoura between November and February, on small liveaboards.
Swimming responsibly
Choose operators who follow the established codes: no touching, no flash photography, and a minimum distance — usually three metres from the body and four from the tail. Ningaloo and Isla Mujeres enforce this with licensed operators and capped numbers, which is why encounters there remain good. Be deliberate about feeding sites: Oslob in the Philippines guarantees sightings by provisioning sharks daily, which alters their natural behaviour and migration — many conservation organisations advise against it, and Donsol nearby offers wild encounters instead. Sunscreen should be reef-safe, and most operations are snorkel-only, since bubbles from scuba disturb the animals.
Frequently Asked Questions
Where can you see whale sharks year-round?
The Maldives’ South Ari Atoll and Cenderawasih Bay in Indonesia have resident populations.
Is it safe?
Yes — whale sharks are filter feeders with no interest in humans. The rules exist to protect the animals, not you.
Should you visit Oslob?
Many conservationists say no, because the sharks are fed daily. Donsol offers wild encounters in the same country.
