Yes. August is one of the best months to swim with humpback whales in Mo’orea, French Polynesia. Every year, humpback whales migrate from their Antarctic feeding grounds to the warmer waters of French Polynesia to breed, give birth and nurse their calves.

August falls within the established whale season, offering opportunities to observe adult humpbacks, mothers with calves and a variety of natural behaviours. However, encounters depend entirely on the animals and ocean conditions.

Our Mo’orea Humpback Whale Expedition takes place August 15–20, 2027, during the seasonal migration.

The expedition includes four full days and one half day on the ocean, allowing us to explore different areas around the island and adapt to changing conditions.

Our expedition includes four full ocean days and one half day, with opportunities for regulated in-water humpback whale encounters whenever conditions and whale behaviour allow.

We dedicate multiple days to the experience because wildlife cannot be scheduled. Some days bring extraordinary observations, while others require patience and exploration.

No. We never guarantee encounters with wild animals.

Although August is an excellent time to visit Mo’orea, whale sightings and swimming opportunities depend on their presence, behaviour, weather and ocean conditions.

Our philosophy at Mind the Seas is simple: we follow nature’s rhythm, not the other way around.

No scuba diving certification is required. Swimming with humpback whales in Mo’orea is a snorkelling activity conducted at the ocean’s surface.

However, you must be comfortable swimming in open water and capable of following your guide’s instructions in changing ocean conditions.

Previous snorkelling experience is strongly recommended.

No. Freediving experience is not necessary.

All whale encounters are conducted at the surface using a mask, snorkel and fins. Participants should not dive down towards whales or attempt to approach them underwater.

Being a confident, relaxed swimmer is far more important than being able to hold your breath.

Our expedition is designed around small in-water groups, with a maximum of six guests accompanied by a qualified guide under the 2026 regulations.

Our aim is to create intimate, responsible encounters without overcrowding the water or placing unnecessary pressure on the animals.

The final group arrangements will comply with the regulations applicable in August 2027.

Under French Polynesia’s 2026 regulations, swimmers must maintain a minimum distance of 15 metres from humpback whales.

We never chase, touch, surround or deliberately approach whales more closely than permitted.

Sometimes whales may move through the same area as swimmers, but all interactions must remain respectful of their natural behaviour.

At Mind the Seas, the animal’s welfare always comes first.

Mother-calf pairs are among the humpback whales that can be observed around Mo’orea during the breeding season.

However, these animals require particular care. Mothers are nursing their calves, and disturbance may affect essential resting and maternal behaviour.

Not every mother-calf sighting is appropriate for an in-water encounter. Our local guides will assess each situation and follow the applicable regulations.

During the austral winter, sea temperatures around Mo’orea generally remain tropical, with regional winter conditions described at approximately 21–27°C.

Actual temperatures vary, and spending extended periods in the water can feel cooler than expected.

A wetsuit is recommended for thermal comfort during whale-swimming excursions.

Mo’orea’s geography offers different coastal exposures, so our local captain may sometimes find more suitable conditions on another side of the island.

However, rough seas, strong winds or poor visibility can make whale swimming unsafe.

When necessary, we may adapt the day’s activities or cancel an ocean excursion. Safety and wildlife welfare always take priority.

Any changes, rescheduling or refunds are governed by the applicable booking conditions.

Swimming with humpback whales can be conducted responsibly when strict conservation rules are followed and the animals remain free to behave naturally.

French Polynesia is a designated marine mammal sanctuary, and whale observation is regulated.

At Mind the Seas, we work with local professionals and follow an animal-first approach. We never encourage chasing wildlife, forcing interactions or disturbing mothers and calves.

We believe that the privilege of observing these animals comes with a responsibility to protect them.

Bring comfortable swimwear, sun protection, a towel and any personal equipment you prefer to use.

Our local ocean operator provides snorkelling equipment and offers wetsuits or flotation equipment, along with refreshments during excursions.

If you have your own mask and snorkel, bringing them can make your experience more comfortable.

We will share a detailed packing list before departure.

Yes, personal underwater photography is possible when it respects the applicable regulations and the guide’s instructions.

Mo’orea can offer extraordinary opportunities to photograph humpback whales in open water.

However, we never approach animals more closely to obtain a photograph, and photography must never interfere with their behaviour.

Commercial filming may require additional permits from the French Polynesian authorities.

The usual route is to fly into Faa’a International Airport in Tahiti (PPT).

From Tahiti, Mo’orea is accessible by ferry, with crossings generally taking approximately 30–45 minutes, depending on the service.

We recommend planning your international arrival with sufficient time for the transfer to Mo’orea.

Detailed arrival information will be provided to confirmed expedition participants.

Mo’orea is much more than a whale-swimming destination.

The island offers spectacular volcanic landscapes, coral reefs, tropical valleys and a rich Polynesian cultural heritage.

During free time, travellers can explore Opunohu Valley, discover local food and traditions, snorkel around coral reefs or observe marine life such as reef sharks, stingrays and sea turtles.

For us, an expedition is about experiencing the destination as a whole, not simply encountering one species.

At Mind the Seas, we create small-group expeditions around extraordinary natural events, with a strong focus on responsible wildlife encounters and meaningful ocean exploration.

Our Mo’orea expedition is not designed around a checklist of guaranteed sightings.

It’s about spending time at sea, learning to understand humpback whales, exploring an exceptional marine environment and sharing the experience with people who have a genuine passion for the ocean.

We believe the best wildlife encounters are never forced.

They are earned through patience, curiosity and respect.

Our Mo’orea Humpback Whale Expedition runs from August 15–20, 2027, with a limited number of guest swimming places.
