Every southern winter, humpback whales travel north from their Antarctic feeding grounds to the warm, sheltered waters around French Polynesia to mate, give birth and nurse their calves. Seeing a mother and calf resting near the reef off Moorea or Tahiti is one of the great wildlife experiences of the South Pacific, and it comes with rules designed to make sure the whales keep coming back.
When the whales are here
Tahiti Tourisme gives the season as July to November. The Tetiaroa Society notes that the first whales can appear in late June and the last leave in early December, and that the regulated watching season generally runs July to November with dates set each year. The whales migrate around 6,000 kilometres each way, and water temperatures of about 21 to 27°C suit newborn calves.
A whale sanctuary
Since 2002, the whole of French Polynesia’s waters has been a sanctuary for whales and other marine mammals. The territory’s environment code regulates any approach for observation or photography, and commercial operators need an authorization to take visitors out.
Where to go
| Island | How you watch | Planning note |
|---|---|---|
| Moorea | Boat trips outside the reef; in-water encounters when permitted | The most operators; easy from Tahiti by ferry |
| Tahiti | Boat trips outside the reef; sometimes visible from shore | Fits a first or last day near the airport |
| Rurutu (Austral Islands) | Cliff-top lookouts and accredited guides by boat | About 600 km from Tahiti; flights on set days |
| Other islands | Opportunistic sightings on lagoon and dive trips | Ask local operators what they see each season |
Rurutu, the whale island
Rurutu, in the Austral Islands, is known as “whale island”. Tahiti Tourisme’s whale season page calls it the best place to admire whales, a kind of nursery where mothers raise their calves. You can watch from the cliffs or go out with an accredited guide. Accommodation is mostly small pensions, and flights are limited, so plan Rurutu as its own block of three or four nights. The island’s limestone caves and coastal walks fill the days when the sea is too rough to go out. An Air Tahiti pass with an Austral extension can combine it with the Society Islands.
Moorea and Tahiti
Most whale outings leave from Moorea and Tahiti, usually as half-day trips. Mornings tend to be calmer. Much of the time is spent searching, and in-water time, when allowed, is short. Bring a long-sleeved layer for the wind on the ride back, a hat, water and a dry bag, and wear a rash guard rather than heavy sunscreen if you might swim. Our Moorea guide helps choose a base close to the departure points.
The rules on the water
The Direction de l’environnement’s guide to observing marine mammals sets out the principles: slow down near whales, approach from the side and run parallel, never cut across their path, circle them, separate a group, come between a mother and calf or trap a whale against the reef, and limit the time spent with each animal. The same guide states that whale watching is forbidden in lagoons, bays and passes. The rules have since been tightened, and good operators brief guests on the current version before every trip.
Swimming with whales
When conditions allow and the captain agrees, small groups may slip into the water with mask and snorkel to watch a resting mother and calf. The Tetiaroa Society stresses that swimmers must not initiate the approach; the whale decides how close it comes. Stay together, keep your fins below the surface, and get out when the guide says so. Many trips end with watching from the boat only, and that is a good outcome too.
What you might see and hear
From the boat, the first sign is usually a spout. Watch for breaches, tail and fin slaps, and groups of males competing to escort a female. Resting mothers and calves often lie quietly near the surface, which is when in-water encounters happen. Underwater, you may hear male humpbacks singing; the Tetiaroa Society notes that only adult males sing, and that the longest song recorded in Polynesia, off Moorea, lasted 54 minutes without a break.
Questions to ask an operator
Is the operator authorized for whale approaches this season? How many guests go on each trip, and how many enter the water at once? What happens if the whales show signs of disturbance? Is there shade and a toilet on board? An operator who answers clearly and puts the rules first is usually the one who gives the best encounter.
Make the visit respectful
Never chase, touch, surround or block a whale, and accept that an operator may decline an in-water encounter. Choose an operator listed as accredited and ask how they apply the rules. Keep noise down on board, and do not fly drones over whales.
Common planning mistakes
Booking the only whale trip on the last day, choosing an operator on price alone, and expecting a guaranteed swim. Our whale migration guide covers month-by-month timing, and our whale photo safari guide covers photography.
Accessibility and individual needs
Ask the operator about minimum ages, swimming requirements and whether children can stay on board while others enter the water. Open-ocean swell outside the reef can be uncomfortable for anyone prone to seasickness, so take precautions before boarding. Larger boats offer more shade and stable seating.
After booking
On the morning of the outing, confirm with the operator that the trip is going ahead and whether in-water encounters are being allowed.
On the day
If no whales are seen or the trip is cancelled, ask about another date, and watch from shore on headlands where whales pass close to the reef.
