Humpback Whale Watching in French Polynesia

South Pacific humpbacks spend the southern summer feeding in Antarctic waters, then migrate north to French Polynesia’s warm, sheltered seas to mate and calve. The first whales usually appear in July, numbers build through August, and September and October bring mothers resting with young calves close to the reef. By late November most have gone.

It’s also the season of song: males sing long, complex songs you may hear through the hull or underwater on a calm day. See our September guide for the peak of the season.

Moorea and Tahiti are the main bases. Whales often travel and rest just outside the barrier reef, so outings reach them quickly. Tahiti Tourisme lists the accredited operators, many of them on Moorea and along Tahiti’s Punaauia coast.

Rurutu, in the Austral Islands south of Tahiti, is famous for whales close to its shores and for land-based sightings from cliffs and beaches. Whales also pass Bora Bora and other Society Islands, and you may spot spouts from the Moorea ferry.

French Polynesia declared its entire exclusive economic zone a marine mammal sanctuary in 2002, and whale watching is tightly regulated. The rules were tightened in 2024 and 2025 and amended again in mid-2026, with some provisions challenged in court, so details such as distances, hours and operator numbers can change between seasons. As of 2026, these principles hold:

Most outings last a few hours. The crew scans outside the reef for blows, then approaches slowly and reads the whale’s behavior. If a whale is calm and conditions allow, the guide may let a small group into the water with mask, snorkel and fins.

Seas outside the reef can be choppy, especially when the trade winds blow, so take seasickness remedies if you need them. Operators set their own minimum ages and swimming requirements for in-water encounters.

It suits anyone comfortable on a small boat, and in-water encounters suit confident swimmers. Families with children who snorkel well love it; see our family guide. A private boat costs more but lets you set the pace.

In July and August, book outings when you book your hotel, and plan a backup day in case wind or sea state cancels a trip. Gigi can build whale days into a Moorea or Tahiti stay so you’re never racing a flight.
