Where to Swim With Whale Sharks: The World's Best Places

The best places to swim with whale sharks are a handful of tropical coastlines where the world’s largest fish gathers to feed near the surface — Mozambique, Mexico, the Maldives, Western Australia, the Philippines, Tanzania, Belize and a few others. The catch is that none of them has whale sharks all the time. Each spot has its own season, set by when the plankton blooms.

We run whale shark ocean safaris in Mozambique, so we’re not a neutral party. But the honest answer to “where’s best?” is that it depends entirely on when you can travel and what kind of encounter you want — so here’s the full picture, including the places that aren’t us.

When can you swim with whale sharks?

Whale sharks are filter-feeders. They go where the food is — dense blooms of plankton and fish eggs — which is why they appear at different places at different times of year:

• Year-round — Mozambique (Tofo and the Bazaruto coast) and the Maldives (South Ari Atoll).
• June–September — Mexico, off Isla Mujeres and Cancún, when hundreds gather offshore.
• Mid-March–August — Ningaloo Reef, Western Australia, after the autumn coral spawning.
• November–March — Mafia Island (Tanzania) and the Gulf of Tadjoura (Djibouti).
• November–June, peak February–April — Donsol, in the Philippines.
• March–June around the full moon — Gladden Spit, Belize, timed to fish-spawning events.
• June–November — the Galápagos (a dive-only encounter, not a surface snorkel).

If your dates are fixed, that list more or less chooses the destination for you. If your dates are flexible, the question becomes what kind of trip you want.

The best places to swim with whale sharks

Mozambique — the year-round, wild option

Where. Tofo, on the Inhambane coast, and the Bazaruto waters off Vilanculos. When. Every month of the year, with the best plankton-driven numbers October–March. Snorkel. No certification needed.

Mozambique is one of the few places on earth where whale sharks are seen every month of the year — there’s a resident population of adolescents rather than a single seasonal pulse, so you’re not betting your whole trip on a two-week window. Encounters are wild (no feeding), the boats are small, and Tofo is also a humpback whale corridor from June to November, so in the right season you can see both giants on one trip. The trade-off: sightings are never guaranteed, and you snorkel in open water off a boat, so you want to be a comfortable swimmer. This is what we do — our Tofo whale shark ocean safari and Vilanculos whale shark ocean safari both run to the no-touch, no-chase code.

Mexico — the biggest aggregation

Where. Off Isla Mujeres and Cancún, on the Caribbean side. When. Roughly June to September. Snorkel.

Each summer, one of the largest known whale shark aggregations on the planet forms in the warm water off the Yucatán — sometimes hundreds of animals feeding on tuna spawn in a patch nicknamed la afuera. It’s a spectacular numbers game, but it’s popular: expect crowded boats and a short, tightly managed in-water slot. Go for the sheer scale, not for solitude.

The Maldives — the other year-round bet

Where. South Ari Atoll (a protected marine area). When. Year-round. Snorkel.

Like Mozambique, the Maldives holds a resident population — here, mostly juvenile males that cruise the atoll reefs all year. You’ll usually swim with one or two animals rather than a crowd, in famously clear, warm water. It pairs naturally with a resort or liveaboard trip.

Western Australia — Ningaloo Reef

Where. Ningaloo Reef, near Exmouth and Coral Bay. When. Mid-March to August. Snorkel.

After the autumn coral spawning, whale sharks arrive along Australia’s largest fringing reef in numbers. Ningaloo is one of the best-organised and best-regulated whale shark operations anywhere — spotter planes, strict codes, small groups — which makes it reliable and responsible, if pricey.

The Philippines — Donsol, not Oslob

Where. Donsol, in Sorsogon. When. November to June, peak February to April. Snorkel.

Donsol pioneered community-based, hands-off whale shark tourism and remains the ethical place to do it in the Philippines. Avoid the confusion with Oslob, a different site where operators hand-feed the sharks to guarantee sightings — a practice many marine scientists and conservationists criticise for changing the animals’ natural behaviour. If you go in the Philippines, go to Donsol.

Tanzania, Belize and Djibouti — the seasonal specialists

• Mafia Island, Tanzania (Oct–Mar) — a quieter, reliable East African season; the closest “rival” to Mozambique on this coast, but more concentrated into a few months.
• Gladden Spit, Belize (Mar–Jun, around the full moon) — whale sharks come for snapper spawning aggregations; a shorter, more specialised window.
• Gulf of Tadjoura, Djibouti (Nov–Feb) — a nursery for juvenile whale sharks; small, off-the-beaten-track, often by liveaboard.

The Galápagos — the one that’s diving, not snorkelling

Where. Darwin and Wolf islands. When. June to November. Scuba only.

The Galápagos is the outlier: here you don’t snorkel with juveniles, you dive with enormous, often pregnant adult females passing remote dive sites in strong currents. It’s an advanced, liveaboard scuba trip — extraordinary, but not a beginner’s encounter.

Do you snorkel or dive with whale sharks?

At almost every site on this list, you snorkel — and that’s not a compromise, it’s the better way to see them. Whale sharks feed on plankton near the surface, so snorkelers get the longest, closest, most natural encounters, and you need no diving certification to go. They cruise slowly while feeding — roughly 3–5 km/h — so it’s surprisingly easy to swim alongside one.

People often search for “whale shark diving,” expecting a scuba experience. With one exception (the Galápagos), scuba isn’t the way to find them: divers usually glimpse whale sharks on surface intervals rather than at depth, because the food is up top. If you’re choosing between the two, snorkel for the whale sharks and save scuba for the reefs and mantas.

Is it ethical to swim with whale sharks?

It can be — if you choose carefully. Whale sharks are listed as Endangered on the IUCN Red List, and well-run wild encounters do them no harm and fund the research and protection that does them good. The things to look for: no touching, no chasing, small in-water groups, respectful distances (typically 3 m from the body, 4 m from the tail), and crews who log sightings for science.

The thing to avoid is provisioning — feeding the sharks to keep them in one place and guarantee sightings, as happens at Oslob in the Philippines. It alters natural behaviour and concentrates animals in busy, boat-heavy water. Wild is better, for them and for you.

How to choose

• Fixed dates? Match your travel window to the season list above — that usually decides it.
• Want the best year-round odds? Mozambique or the Maldives.
• Want the biggest spectacle and don’t mind crowds? Mexico in summer, or Ningaloo in the autumn.
• Want it wild, ethical and uncrowded — and maybe humpbacks too? Mozambique. Tofo and the Bazaruto coast give you whale sharks every month and humpback whales June–November, on small boats with local crews.

Still not sure?

If Mozambique is on your list, tell us roughly when you’d travel and we’ll be straight with you about what sightings have been like — and whether Tofo or the Bazaruto coast off Vilanculos suits your trip better. Have a look at our Tofo whale shark ocean safari and our Vilanculos whale shark ocean safari, or message us on WhatsApp and we’ll help you plan it.
