Excerpt:
Discover when to see whale sharks in Talisayan, Berau, how to reach the fishing platforms from Derawan Island, what affects sightings, and how to swim responsibly around the world's largest fish.
Off the coast of Talisayan in Berau, East Kalimantan, one of Indonesia's most remarkable wildlife encounters takes place around traditional fishing platforms known locally as bagan.
This is where whale sharks — Rhincodon typus — are regularly observed swimming close to the surface.
Bagan fishermen use lights at night to attract small fish. As these fish concentrate around the nets, whale sharks may approach the platforms to feed on the abundance of small prey in the surrounding water.
The relationship between whale sharks and fishing platforms in Talisayan has been documented through research and conservation work in the Berau region.
But before planning a trip, there is one important thing to understand:
Whale sharks are wild animals. No month, date, guide, or tour operator can guarantee a sighting.
Their movements are influenced by food availability, fishing-platform activity, weather, currents, sea conditions, and natural migration.
When Is Talisayan Whale Shark Season?
The short answer
Whale sharks can occur in Talisayan throughout the year, but the chance of seeing them is not equally predictable every month.
WWF research on whale sharks in Berau reported year-round occurrence in Talisayan. Earlier research also found that sightings were commonly associated with the period when lift-net fishing platforms operated during the southern monsoon, described as roughly June to October or, more broadly, May to December.
This means the phrase “Talisayan whale shark season” should not be interpreted as a fixed wildlife calendar.
A better way to think about it is as a travel window.
In practical terms:
whale sharks may be encountered throughout the year;
sightings are strongly connected to active fishing platforms;
fishing-platform activity changes with weather and seasonal sea conditions;
recent reports from local fishermen and guides are particularly valuable;
and no period can guarantee a whale shark encounter.
If whale sharks are the main reason for your trip, check recent local sightings before travelling.
Why Do Whale Sharks Come to Talisayan?
Whale sharks do not permanently live beside one particular fishing platform.
They are free-ranging marine animals.
One reason they are regularly observed around Talisayan is the presence of traditional bagan fishing platforms.
At night, lights on the platforms attract schools of small fish. These fish gather around the nets, creating a concentrated food source that can attract whale sharks.
Despite their enormous size, whale sharks are filter feeders.
Their diet consists of relatively small organisms including zooplankton, fish eggs and small pelagic fish.
This feeding ecology explains why the waters around an active bagan can become one of the best places to observe them.
Where Is Talisayan?
Talisayan is a coastal district in Berau Regency, East Kalimantan, Indonesia.
The whale shark experience does not usually take place directly from a beach or harbour.
The encounter sites are offshore, around fishing platforms operating in the waters near Talisayan.
For travellers staying in the Derawan Islands, the journey is commonly made by speedboat.
From Derawan Island, departures generally take place before sunrise.
Derawan.id currently uses approximately 4:00 a.m. as the normal departure reference, with the crossing taking around 1.5 hours under suitable conditions. The exact journey can change depending on the active fishing platform, boat, weather, waves and currents.
Why Leave Derawan at 4 A.M.?
A 4 a.m. departure may sound unusually early for a holiday.
But a Talisayan whale shark trip is different from a normal island-hopping day.
The objective is to reach the fishing-platform area early in the morning while local fishing activity is still relevant to the encounter and before conditions change later in the day.
Leaving Derawan at around 4 a.m. allows the boat to reach the Talisayan area as daylight begins.
An early departure also provides additional time if the active fishing platform is farther away than expected.
However, 4 a.m. should not be treated as a universal rule.
The actual departure time should follow local reports, weather, sea conditions and the location of active bagan.
How Are Whale Sharks Located?
A whale shark trip is not like visiting a wildlife enclosure where the animal remains in the same place every day.
Whale sharks move continuously.
Local information is therefore extremely important.
Before an excursion, guides may need to determine:
which fishing platforms are operating,
whether whale sharks have recently been reported,
current wind and sea conditions,
and whether conditions are safe for visitors.
This is why recent local sighting information can be more useful than simply choosing a month on a calendar.
A good month can still produce a day without whale sharks.
Likewise, sightings can occur outside the period travellers usually consider the main season.
Are Whale Sharks Always Present in Talisayan?
No.
This is one of the most important things to understand before travelling.
Whale sharks are wild animals moving freely through the ocean.
Talisayan is a recognised whale shark area in Berau, but their presence at a specific fishing platform on a particular morning cannot be guaranteed.
It is therefore more accurate to speak about:
the chance of seeing whale sharks
rather than:
a guaranteed whale shark swim.
This approach gives travellers realistic expectations while respecting the natural behaviour of the animals.
Talisayan vs Whale Sharks Around Derawan Island
Talisayan is not the only place in Berau where whale sharks have been documented.
Research has also recorded them around Derawan Island.
A WWF publication from 2019 reported that, in the observations available at the time, whale sharks occurred throughout the year in Talisayan while observations around Derawan Island were concentrated around November to March.
Some identified individuals were recorded in both locations, indicating that the waters between Talisayan and Derawan form part of the same broader whale shark range in Berau.
This is useful ecological information, but it should not be treated as a current guarantee of where whale sharks will appear.
For trip planning, recent field reports remain more relevant than historical seasonal patterns alone.
Talisayan Whale Shark Quick Facts
Common name: Whale shark
Indonesian name: Hiu paus
Scientific name: Rhincodon typus
Location: Talisayan waters, Berau Regency, East Kalimantan
Habitat: Tropical and subtropical seas
Diet: Zooplankton, fish eggs and small marine organisms
Feeding method: Filter feeding
Protection in Indonesia: Fully protected
Visitor activity: Wildlife observation and regulated snorkelling
Whale sharks are the largest fish species on Earth.
Current conservation guidance for the Berau region also notes that the species is fully protected in Indonesian waters.
Although the word “shark” is part of their name, whale sharks are not human-hunting predators.
They feed by filtering small organisms from seawater.
Their bodies are nevertheless extremely large and powerful, which is why visitors must follow wildlife-interaction and safety guidelines in the water.
Responsible Whale Shark Swimming
Seeing a whale shark at close range can be unforgettable.
But the objective should never be to get as close as possible for a photograph.
The goal is to observe a wild animal without changing its natural behaviour.
Current whale shark tourism guidance developed with WWF Indonesia, local authorities and stakeholders in Berau includes several important rules.
1. Listen to the safety briefing
Your guide should explain the conditions, safety procedures, interaction rules and permitted behaviour before anyone enters the water.
2. Enter the water quietly
Use the ladder and enter calmly.
Do not jump into the water near a whale shark.
3. Never touch a whale shark
Do not touch, grab, hold onto or attempt to ride a whale shark.
Allow the animal to control the interaction.
4. Never chase one
If a whale shark swims away, let it go.
Do not pursue it for a photograph or video.
5. Do not feed whale sharks
Visitors should never feed whale sharks.
Artificial feeding can alter natural behaviour and create unhealthy interactions between wildlife and people.
6. Avoid sudden movements and loud noise
Remain calm in the water.
Avoid shouting, splashing excessively or making sudden movements around the animal.
7. Photography is allowed, flash is not
Underwater photography and video are permitted, but flash and strobe lighting should not be used.
8. Do not use underwater scooters or jet skis
Motorised devices that can chase or disturb whale sharks should not be used during an interaction.
9. Respect group and time limits
Current guidance for Berau limits each snorkelling group to a maximum of six snorkellers, with a maximum interaction time of 15 minutes before rotating groups.
10. Leave nothing in the ocean
Take all rubbish back to the boat.
Because whale sharks feed by filtering seawater, marine debris — especially plastic — can become a serious threat.
Is It Safe to Swim with Whale Sharks?
Whale sharks do not hunt people.
Their diet consists of organisms far smaller than humans.
That does not mean swimming in the open ocean is risk-free.
Visitors are still:
in open water,
around boats and fishing platforms,
exposed to changing currents,
and swimming near an extremely large wild animal.
Follow your guide's instructions, use appropriate safety equipment and never enter the water if conditions or your swimming ability make the activity unsafe.
What Should You Bring?
For an early-morning Talisayan trip, useful items include:
swimwear or a rash guard,
towel,
dry bag,
sun protection,
drinking water,
action camera or underwater camera,
spare batteries,
seasickness medication if needed,
and dry clothes for the return journey.
If you use an underwater camera, remember that flash and strobe lighting should not be used around whale sharks.
Weather and Sea Conditions
The journey between the Derawan Islands and Talisayan crosses open water.
Plans therefore need to remain flexible.
Wind, waves, rain, visibility and general marine safety can affect:
departure time,
travel time,
which fishing platform can be visited,
whether snorkelling is possible,
or whether the excursion should operate at all.
Safety should always take priority over a whale shark sighting.
If conditions are unsafe, postponing or cancelling the activity is the correct decision.
How to Choose the Best Time to Visit
If seeing whale sharks is one of the main reasons for your Derawan trip, use three layers of information.
First: consider the broader seasonal window.
Historical research links frequent sightings around operating fishing platforms with the southern monsoon, roughly June–October or within a broader May–December period.
Second: do not rely on the month alone.
Whale sharks may appear outside that period, and they may also be absent on a particular day during it.
Third: check recent local reports.
Information from fishermen and local guides about fishing-platform activity and sightings in the previous few days is often far more useful for understanding current conditions.
Why Talisayan Is Special
Talisayan is more than a place to take a photograph with a very large fish.
It represents a fascinating connection between the ocean, traditional fisheries, coastal communities and one of the most extraordinary marine species on Earth.
Fishing platforms that form part of local livelihoods have also become places where people can observe whale sharks at close range.
Conservation guidance for Berau identifies these waters as important feeding and development areas for juvenile whale sharks.
That makes responsible tourism particularly important.
Whale shark tourism in Talisayan should not be about creating as many encounters as possible.
It should be about allowing travellers to experience a wild ecosystem while protecting the animals and communities that make the experience possible.
Talisayan Whale Shark FAQ
What is the best season for whale sharks in Talisayan?
Whale sharks can occur throughout the year. However, sightings are closely connected to fishing-platform activity, weather, food availability and sea conditions. Historical research links frequent sightings with the southern monsoon period around June–October or, more broadly, May–December. No month guarantees a sighting.
Can I see whale sharks from April to December?
This can be treated as a broad travel-planning window rather than a guaranteed biological season. Always check recent sightings and fishing-platform activity before travelling.
Are whale shark sightings guaranteed?
No. Whale sharks are wild animals and sightings cannot be guaranteed.
What time do boats leave Derawan Island?
Trips commonly leave before sunrise. Derawan.id currently uses approximately 4:00 a.m. as a departure reference, although the actual time may change according to sea conditions, active fishing platforms and local reports.
How long does it take from Derawan to Talisayan?
Around 1.5 hours by speedboat is a useful general estimate. Actual travel time depends on the boat, weather, sea conditions and the location of the active fishing platform.
Can visitors swim with the whale sharks?
Yes, when conditions allow and when the activity follows local interaction rules and guide instructions.
Are whale sharks dangerous?
Whale sharks are filter feeders and do not hunt humans. However, they are enormous wild animals and the activity takes place in open water, so visitors must still follow safety instructions.
Can I touch a whale shark?
No. Visitors should never touch, chase, ride or otherwise disturb a whale shark.
Can visitors feed them?
No. Visitors should not feed whale sharks.
Can I bring a GoPro or underwater camera?
Yes. Photography and video are allowed, but flash and strobe lighting should not be used.
How long can I swim with a whale shark?
Current guidance in Berau limits snorkelling groups to a maximum of six people with a maximum interaction time of 15 minutes.
What happens if the weather is bad?
The activity may be delayed, changed or cancelled when conditions are unsafe. Visitor safety and wildlife protection should always come first.
Before You Travel to Talisayan
Travel with the right expectations.
A whale shark is not an attraction scheduled to appear at a particular hour.
You are entering the habitat of a wild animal.
Some mornings may bring the unforgettable sight of several whale sharks slowly moving around a fishing platform.
On another morning, the ocean may offer no encounter at all.
That uncertainty is part of observing wildlife in nature.
Check current sea conditions, fishing-platform activity and recent sightings before departure — and if you are fortunate enough to meet a whale shark, enjoy the moment without touching, chasing or disturbing it.
Talisayan is not simply a place to “swim with whale sharks.”
It is part of an important marine ecosystem in Berau that deserves to be experienced responsibly and protected for the future.
