Celebrating International Whale Shark Day – 30 August 2026
Few wildlife encounters compare with seeing a Whale shark (Rhincodon typus) in the wild. Reaching around 10–12 metres in average adult length, with exceptional individuals growing even larger, Whale sharks are the largest fish in the ocean. Despite their enormous size, these gentle giants are filter feeders, swimming through the ocean feeding primarily on plankton and other small organisms. Their distinctive pattern of white spots and stripes also makes every individual whale shark unique.
Every year on 30 August, International Whale Shark Day celebrates these incredible animals while raising awareness of the threats they continue to face. To celebrate International Whale Shark Day 2026, here are 10 of the best destinations in the world to swim, snorkel or scuba dive with Whale sharks.
1. South Ari Atoll – Maldives
Best time: Year-round, with excellent conditions December–May
Experience: Snorkeling & Scuba Diving
The Maldives is one of the world's most famous Whale shark destinations, and South Ari Atoll is particularly special because Whale sharks can potentially be encountered throughout the year.
The warm tropical waters along the southern edge of the atoll provide habitat for predominantly juvenile Whale sharks, with individuals often measuring around 3–8 metres. Research suggests the area provides these younger sharks with a relatively safe environment and consistent food supply.
Unlike destinations where Whale sharks appear during a very short seasonal aggregation, the possibility of year-round sightings makes South Ari Atoll an outstanding destination for anyone hoping to experience their first Whale shark.
2. Utila – Bay Islands, Honduras
Best time: Year-round, with peaks around March–April and August–September
Experience: Swimming, Snorkeling & Scuba Diving
The small Caribbean island of Utila, part of Honduras’ Bay Islands, is one of the best-known Whale shark destinations in the Caribbean. Whale sharks can be encountered throughout the year, although sightings tend to peak during March and April and again around August and September. The sharks are often located when boats spot feeding activity at the surface, sometimes accompanied by groups of seabirds and schooling fish.
One of Utila’s biggest attractions is that Whale shark encounters occur alongside an already excellent diving destination. The surrounding waters feature colourful Caribbean reefs, walls, turtles, rays and abundant tropical marine life.
Most dedicated Whale shark encounters involve snorkeling, allowing participants to enter the water when a shark is located and observe it swimming naturally through the open ocean. With warm Caribbean waters, excellent diving and the possibility of encountering the world's largest fish, Utila makes a fantastic addition to any Whale shark bucket list.
3. Ningaloo Reef – Western Australia
Best time: March–July
Experience: Swimming & Snorkeling
The UNESCO-listed Ningaloo Coast is one of the world's great marine wildlife destinations. Every year, Whale sharks arrive following the mass coral spawning and seasonal increase in plankton, creating one of the most famous opportunities to swim alongside these gentle giants.
Australia also has established regulations surrounding Whale shark tourism, helping manage interactions between boats, swimmers and the animals. Responsible management is particularly important because Whale sharks spend considerable time close to the surface, where vessel traffic can present a risk.
Combine Whale sharks with Ningaloo's coral reefs, manta rays, turtles and other marine life and you have one of the world's ultimate ocean adventures.
4. Isla Mujeres & Isla Holbox – Mexico
Best time: June–September, particularly July–August
Experience: Swimming & Snorkeling
During the northern hemisphere summer, the waters around Mexico's Yucatán Peninsula can host spectacular aggregations of Whale sharks.
The area between Isla Holbox and Isla Mujeres is regarded as one of the world's most consistent seasonal whale shark destinations, with aggregations sometimes involving very large numbers of animals feeding in plankton-rich waters.
Whale shark encounters here are regulated and scuba diving within the Whale shark interaction area is prohibited, making this primarily a snorkeling experience. Manta rays may also be encountered during Whale shark season, making an already remarkable day on the water even more memorable.
5. Galápagos Islands – Ecuador
Best time: June–December
Experience: Scuba Diving
For experienced scuba divers, encountering a Whale shark at Darwin Island in the Galápagos must rank among the world's ultimate shark experiences. The famous Pillars of Evolution, formerly known as Darwin's Arch before its collapse in 2021, is renowned for spectacular pelagic marine life.
Whale sharks are among an extraordinary collection of animals that can be encountered here alongside schooling hammerhead sharks, Galápagos sharks, rays, turtles and other large ocean species. During Whale shark season, humpback and pilot whales may also be present.
Strong currents and remote diving conditions mean this destination is generally better suited to experienced divers, but for those with the skills, the rewards can be exceptional.
6. Tofo – Mozambique
Best time: Particularly November–February
Experience: Snorkeling & Scuba Diving
The waters around Tofo Beach in Mozambique are famous for big marine animals. Productive waters and plentiful plankton support Whale sharks as well as manta rays, dolphins, turtles and numerous other species.
Tofo is one of Africa's important Whale shark destinations, particularly between November and February. The area sometimes referred to as Whale Shark Alley includes several dive sites where encounters are possible, while dedicated ocean safaris provide opportunities to snorkel with Whale sharks found near the surface.
Add the possibility of humpback whales during their seasonal migration and Mozambique becomes a spectacular destination for marine wildlife enthusiasts.
7. Socorro Islands – Mexico
Best time: November–December
Experience: Scuba Diving
The Revillagigedo Archipelago, commonly known as the Socorro Islands, is one of the world's most spectacular destinations for encounters with large pelagic marine life. Located in the eastern Pacific Ocean, approximately 400 kilometres off Mexico's Baja California Peninsula, these remote volcanic islands are accessible primarily by liveaboard and are famous for their incredible shark diving.
Whale sharks can be encountered around the islands, particularly during the early and later parts of the diving season. Encounters are generally less predictable than destinations with large seasonal Whale shark aggregations, but seeing one underwater while scuba diving makes the experience particularly special.
The remote location, deep water and sometimes challenging ocean conditions make Socorro best suited to experienced divers. However, for those looking for a true big-animal diving adventure — with the possibility of encountering a Whale shark during the dive — Socorro deserves a place among the world's great shark diving destinations.
8. Mafia Island – Tanzania
Best time: October–March
Experience: Swimming & Snorkeling
Off the coast of Tanzania lies Mafia Island, an increasingly celebrated destination for Whale shark encounters in the western Indian Ocean.
Seasonal concentrations of plankton attract whale sharks into the waters surrounding the island, creating excellent opportunities for snorkeling encounters.
Compared with some of the world's busiest Whale shark destinations, Mafia Island can offer a quieter and more adventurous experience. Combined with coral reefs, tropical islands and the biodiversity of the western Indian Ocean, it is a fantastic destination for travellers seeking Whale sharks somewhere a little further off the traditional tourist trail.
9. La Paz – Baja California Sur, Mexico
Best time: October–May
Experience: Swimming & Snorkeling
The Sea of Cortez has been described as one of the world's great natural aquariums, and Whale sharks are among its most impressive seasonal visitors. Young Whale sharks regularly enter the sheltered Bay of La Paz, sometimes swimming surprisingly close to shore.
The bay's relatively protected conditions can make it an excellent destination for snorkelers and first-time Whale shark encounters. The wider region also offers outstanding marine wildlife experiences including sea lions, rays, dolphins, whales and numerous shark species.
10. Thailand – Andaman Sea
Best time: Approximately November–April
Experience: Primarily Scuba Diving
Thailand deserves a place on any Whale shark bucket list — although sightings here can never be guaranteed. Whale sharks occasionally travel through the Andaman Sea, appearing at some of Thailand's most celebrated dive sites.
Richelieu Rock, north of the Similan Islands, is particularly famous for its marine biodiversity and the possibility of encounters with large pelagic species, including Whale sharks.
Whale sharks can also occasionally be encountered around other areas of the Andaman Sea, making every sighting a particularly special experience.
Unlike destinations where sharks form predictable seasonal aggregations, a whale shark appearing unexpectedly during a dive in Thailand can turn an already beautiful dive into one you will remember for the rest of your life.
Remember: We Are Visitors in Their Ocean
Swimming beside a Whale shark can be an unforgettable experience, but our desire to see these animals should never come at their expense. Whale shark tourism can negatively affect animals when poorly managed. Boats can cause propeller injuries, while crowds, touching, chasing, feeding or repeatedly blocking a shark's swimming direction can interfere with its natural behaviour and feeding.
When choosing a Whale shark experience:
Choose responsible operators that follow recognised Whale shark interaction guidelines.
Never touch, ride or hold onto a Whale shark.
Never deliberately block or chase an animal.
Maintain an appropriate distance and give the shark space to move freely.
Avoid flash photography.
Never encourage wildlife harassment simply to capture a photograph or video.
Follow local regulations and your guide's instructions.
Where possible, choose encounters involving naturally occurring animals rather than operations dependent on artificial feeding.
Turn Your Whale Shark Encounter Into Citizen Science
Seeing a Whale shark is exciting. But what if your encounter could also help scientists learn more about the species?
Every Whale shark has a unique pattern of spots, particularly around the area behind its gills. Like a human fingerprint, these patterns can be used to identify individual animals from photographs. Photo-identification allows researchers to recognise individual whale sharks and study their movements, distribution and re-sightings.
Useful information can include:
Photographs or video of the whale shark
Date of the encounter
Location
Estimated size
Sex, when identifiable
Distinctive scars or markings
Additional observations about the animal or encounter
Even a photograph or video taken during a holiday could potentially help identify an individual shark or contribute another sighting to its history.
