A humpback whale mother with her calf underwater off Moorea

Experiences · Whale season

Winter belongs
to the whales.

Humpbacks cross from Antarctic feeding grounds to calve in these warm, protected waters every austral winter. Meeting them is a privilege with rules.

01 / The migration

Born in
the lee of islands.

From roughly July to November, humpback whales rest, court, and give birth along the islands' sheltered flanks, having swum thousands of kilometres from polar feeding grounds. Mothers with calves hug calm water — which is why encounters here can be so close, and why the calmest possible behavior from boats and swimmers matters so much.

French Polynesia declared its entire exclusive economic zone a marine mammal sanctuary in 2002 — one of the world's largest — and the whale-watching rules that grew around it are the reason the animals keep choosing these shores.

What to expect

Winter trade winds chop afternoons; mornings are kinder

Seasickness plan advised
06Ethics

Engines idle, distances kept, calves never separated from mothers

Walk away from cowboys

03 / In the water

Guests,
not visitors.

Where swims are allowed, they are slow-motion affairs: small groups slipping in quietly at the guide's signal, floating still at respectful distance while a mother rests below and a calf rises to breathe. No chasing, no diving down, no touching — the whales decide everything. Many of the best moments of a season happen entirely from the boat.

Plan around it

Build the trip
whale-first.

If whales are the point, anchor dates in August–October, base on Moorea or Rurutu, book two outings rather than one, and keep a flex morning for weather. The second trip is the insurance policy.

When to go, month by month
