Moorea is an island in French Polynesia located in the South Pacific Ocean, near Tahiti, where seasonal offshore waters support regulated freediving and snorkeling encounters with migrating humpback whales. The area is known for its warm, clear water with visibility often exceeding 30 m and rich marine biodiversity including dolphins and pelagic shark species; underwater features around the island include lagoons, reef walls, and canyons that support diverse fish and coral communities. Whale-related activities take place in open ocean environments and are focused on respectful wildlife observation. Contact licensed local operators or guides for permits and scheduling of whale encounters and other marine activities.

• Visibility: about 30 m to 40 m in clear conditions.

• Depth Range: Whale swim areas are in open ocean where depth quickly extends beyond reef zones; general snorkeling occurs from the surface to approximately 5 m near marine wildlife.

• Water Temperature: range from about 24 °C to 29 °C depending on season and location.

• Water Conditions: mild currents and variable surface chop; lagoons and reef sites are generally calmer.

• Seasonality: Whale in-water activities are permitted only from July to November, depending on the year; peak whale presence typically occurs late July through early November.

• Transportation: Access to Moorea is by regional travel from Tahiti, typically via a ferry crossing from Papeete that takes about one hour or by short regional flights to Moorea Airport, followed by local transport to departure points for marine tours.

• Local rules: Whale swim activities are regulated: only six guests plus a guide are permitted in the water per tour, boats must maintain prescribed distances from whales, and interactions begin when safe and in compliance with French Polynesian regulations.
