Tiger Sharks in Fuvahmulah, Maldives: What the Dive Really Is

That image, the striped shape coming up from the blue, is what made the tiger sharks of Fuvahmulah famous. It also hides a long and slightly uncomfortable story about why the sharks gather in this one place.

I want to describe the diving honestly: what scientists have measured, what the codes of conduct say, and what I could not confirm. For us this is not a trip we offer today, and I explain why at the end.

What the diving actually is

Tiger sharks are around Fuvahmulah all year, according to dive-industry sources such as PADI. The island sits in the Maldives' southern Gnaviyani Atoll. The diving is done on scuba, with sharks passing close to a group at a site locals call Tiger Harbour.

Dive-travel guides describe the southwest monsoon, roughly May to October, as bringing rougher seas and lower visibility. Those are planning guides, not scientific measurements, so please treat the details as approximate and ask the dive centre about conditions for your dates.

It is worth saying clearly what this is not. It is not a swim with whales. This is diving, with a licensed dive centre under Maldivian rules, and the animal is a large predator that people usually meet from the bottom, not from the surface.

How many tiger sharks gather at Fuvahmulah?

A 2024 paper in Scientific Reports by Vossgaetter and colleagues, titled "Non-invasive methods characterise the world's largest tiger shark aggregation in Fuvahmulah, Maldives", identified 239 individual tiger sharks over seven years, using photo identification and laser photogrammetry. About 84.5 percent were female. Adult females came back to the site year after year, and the authors estimate they stay about 61 days per visit. They suggest the adults carry their pups near the island and may breed about every two years, and they link the site to food all year round and warm water.

A separate source, a shark and ray areas factsheet from the ISRA project, lists 236 identified sharks and calls it the only known tiger shark aggregation in the Maldives. The numbers are slightly different because they come from different periods and methods. For the figure, I would trust the peer-reviewed paper.

A 2025 study in Behavioural Processes, based on video of the bait site from 2023 and 2024, recorded 36 social interactions among 40 mature females and described a hierarchy based on size. I mention it because it shows the sharks are not simply passing by. They are a regular community, in one spot.

The uncomfortable part: why the sharks gather here

The Scientific Reports paper notes that tiger sharks visit the harbour area, drawn by discarded fish waste. One local operator's account, which I cannot verify on my own, says the city council stopped fishermen throwing waste into the harbour in 2017, and that a dive centre then began placing it at the entrance, which concentrated the sharks in one spot.

This matters because the Maldives' own Diving Regulation, which comes from the Tourism Act (No. 2/99), prohibits feeding sharks. That is stated in the shark-interaction codes of conduct developed by the Ocean Country Partnership Programme. Yet one diver's account describes operators baiting the water once the divers were settled, and an editorial in January 2026 called for stricter rules and consistent enforcement. The Ministry and Fuvahmulah City Council commissioned a review of shark diving, focused on supplementary feeding.

I do not know how far the ban is enforced today, or how each dive centre handles food. I could not confirm it, and I would rather say so than guess. If you book anywhere in Fuvahmulah, ask the centre directly how the sharks are attracted, and whether they will answer in writing.

The codes of conduct, and what they ask of divers

Together with the local dive industry and the authorities, experts drafted shark diving codes of conduct for Fuvahmulah. They cover thresher sharks, tiger sharks at Tiger Harbour and other predatory sharks, with versions for divers and for guides. The tiger shark code asks for a maximum of four divers per guide, and for divers to stay at least five metres from the sharks. One dive operator's pages give the same kind of ratio, but that is one company's practice, and the codes are described as guidance for operators, not a law.

I have only summarised two numbers here. Please read the codes themselves before you dive, because I could not check every other line against the current version. They are published on the JNCC data site, listed below.

A good code is something you can use as a checklist on the boat. Count the divers per guide. Watch what the crew does with the water around the site. Ask what happens if a shark does not show up, and listen for whether the answer is "we wait" or "we change something".

A species that needs space

The IUCN lists the tiger shark as Near Threatened globally, assessed in 2018. Australian assessors note that tiger sharks are thought to reproduce only about every three years, which limits how fast a population can recover from fishing. That is relevant here: a gathering of mostly mature females is precious, and it is also easy to change.

Food-based diving is debated all over the world. Provisioning can change where animals spend their time and how they behave around people. I do not think the evidence in Fuvahmulah is settled either way, and that is exactly why we are careful. You can read more in our pieces on whether Fuvahmulah's tiger sharks are eating wild food and baited shark dives and what the evidence shows.

If you are a certified diver and you decide to go, a few small choices help. Dive with a centre that answers questions openly, wear dark, neutral gear, and keep your hands to yourself. A small underwater camera works well without lights, and a roll-top dry bag keeps electronics safe on the boat ride. Please also think about the flight. The Maldives is far from most places, so one longer stay makes more sense than several quick trips.

Wildlife encounters are unpredictable. Diving with tiger sharks should always follow local regulations and experienced professional guidance.

Where Ocean Calling stands

This is not an Ocean Calling trip today. Before it could be, we would want the dive centre's feeding protocol answered in writing. Until then, we will not describe this site as bait-free, because we do not know that it is, and the published research says fish waste is part of why the sharks are there. Our own hosted retreats are for groups of six at most, with unhurried days and every activity optional.

You can read more about the scuba side in what scuba divers should know about Fuvahmulah's tiger shark dive, and see how rules compare across countries on wildlife and the law. If this made you curious about the ocean in a slower way, you can explore our retreats.

Questions people ask

When can you see tiger sharks in Fuvahmulah?

Dive-industry sources such as PADI say tiger sharks are present all year. Conditions change with the monsoon seasons, and no sighting is guaranteed, so ask the dive centre about your dates.

Is it a swim with whales?

No. It is guided scuba diving with a licensed dive centre. We are not aware of any lawful swim-with-whales product in the Maldives, so be careful if anyone sells one.

Is shark feeding legal in the Maldives?

The shark codes of conduct state that the Maldives Diving Regulation, which comes from the Tourism Act (No. 2/99), prohibits feeding sharks. Reports describe practices at the site that raise questions, and I could not confirm how this is enforced today.

What do the codes of conduct ask divers to do?

The Tiger Harbour code asks for no more than four divers per guide and at least five metres from the sharks. Read the current document before you dive, because codes are guidance and can be updated.

Are tiger sharks endangered?

The IUCN lists the tiger shark as Near Threatened globally, assessed in 2018. Slow reproduction and fishing pressure are the main concerns.

How many tiger sharks are there at Fuvahmulah?

A 2024 Scientific Reports paper identified 239 individuals over seven years, about 84.5 percent female. It describes the site as the world's largest tiger shark aggregation.

Wildlife encounters are never guaranteed and never forced. Ocean Calling works only with vetted, ethical local operators, and every animal is free to approach, or not, entirely on its own terms.
