The Polynesian Islands have a tropical climate, with constant warm sea temperatures year-round, providing ideal conditions for water activities such as snorkelling and scuba diving in French Polynesia. Knowing the water temperature at the time of your trip will help you determine whether this is the best time to dive in French Polynesia.
The average surface water temperature ranges from 26°C (79°F) to 29°C (84°F). However, it varies slightly depending on the island, the time of year, and ocean currents. The coldest month is August, and the warmest months are March and April. Water visibility gets better from June to September. However, seasonal migrations of marine animals can sometimes have greater importance when a scuba diver decides to go diving in French Polynesia. Scuba divers must note that the water temperature drops with depth and with currents.
