Where to see whale sharks

Rhincodon typus

The whale shark is the largest fish alive, and despite the name it is a shark, not a whale. It feeds by cruising slowly near the surface with its mouth open, filtering plankton and small fish. Most animals encountered by divers and snorkellers are juvenile males in the 4–8 meter range. Because they follow food, sightings are strongly seasonal in most of the world — with a few standout places where they linger year-round.

Best places to see whale sharks

How to identify a whale shark

• Broad flat head with a mouth right at the front — unlike most sharks, whose mouth sits underneath.
• A checkerboard of pale spots and stripes; the pattern behind the gills is unique to each individual.
• Slow, sculling tail beats near the surface — they cruise, they don't dart.

Meeting them responsibly

• Keep at least 3 meters from the body and 4 meters from the tail — the tail is powerful.
• No touching, no riding, no blocking its path. Swim alongside, never in front.
• Cut the engine when a shark is near the boat; propeller strikes are a leading cause of injury.

Frequently asked questions

Where can I swim with whale sharks?

South Ari Atoll in the Maldives is the only place with a documented resident population, so it works year-round. Ningaloo Reef in Australia, Isla Mujeres in Mexico and Donsol in the Philippines all have strong, predictable seasons.

When is whale shark season?

It varies by destination: year-round in South Ari, March–July at Ningaloo, June–September off Isla Mujeres, and February–April in Donsol. Each location's page has the detail.

Are whale sharks dangerous?

No. Despite being the largest fish in the sea, whale sharks are filter feeders that eat plankton and pose no threat to swimmers. Keep clear of the tail, which is powerful, and never block the animal's path.
