Diving & Snorkelling with Whale Sharks

Displaying a curious nature and great grace despite their huge size, whale sharks represent a highlight of any diving or snorkelling holiday. More closely resembling whales in many aspects, these giants are in fact part of the shark family.

Feeding primarily on plankton, whale sharks are found in tropical locations around the globe. Both diving and snorkelling encounters with these ancient giants are possible, ensuring divers and non-divers alike can marvel at their beauty.

Habitat and biology

Found in tropical waters from Honduras to the Maldives, these huge, docile members of the shark family are characterised by their wide mouths, distinctive blue-grey colouring with white spots and a large, crescent-shaped tail. Primarily plankton feeders and ocean wanderers, whale sharks are also known to eat small fish, even interacting with local fishermen in Cenderawasih Bay in Indonesia.

Whale sharks are the largest fish in our oceans, averaging around 9-10 metres in length, but are thought to reach sizes of up to 18 metres. They are also considered to be one of the most ancient species on our planet, pre-dating the dinosaurs.

Where to encounter whale sharks

Whale sharks can be seen in a number of locations around the world. The Maldives and in particular the South Ari Marine Park Area offer some of the most consistent sightings. Depending on the time of year, they visit the eastern or the western side of the atolls, feeding on the plankton rich warm water. The largest numbers of whale sharks are seen around the Baa Atoll from May to October each year.

Galapagos between May and November, Mexico’s Yucatan Peninsula from June to September, Mafia Island in Tanzania from November to March, and Mozambique’s southern shores from November through to May. The Sea of Cortez, on Mexico’s west coast is home to whale shark populations throughout the year. In the northern reaches the season runs July to November and around La Paz encounters with these gentle giants is best from October through to May.

Whale sharks also gather in a number of places in the Philippines. From November to May, large numbers are seen in the waters around Donsol, while Tubbataha offers superb opportunities from March through to May each year. Sightings are also possible in Thailand, Christmas Island, Indonesia, Madagascar and Cuba.

Diving or snorkelling with whale sharks

Diving and snorkelling encounters are possible with whale sharks, however not in every location. Snorkelling can in fact bring some advantages over diving in certain situations. Encounters are often in very shallow waters, while snorkellers are generally able to move faster than divers. Snorkelling with whale sharks is possible in Mafia Island in Tanzania and Ningaloo Reef in Australia as well as in the Maldives, Mexico, St Helena and the Philippines. Please contact us for more details.

In other locations, scuba diving represents the better option. Sea conditions in Mozambique lend themselves to diving encounters, and in the Maldives, both diving and snorkelling opportunities are hugely rewarding. In the Galapagos islands, conditions tend to be too challenging for snorkelling and diving is preferable. If you have always dreamt of diving with whale sharks join us on our Galapagos whale shark diving trip where we are joined by marine biologist Sofía Green Iturralde, cruising the islands during the peak of the whale shark aggregation.
