When Is the Best Time for a Bora Bora Lagoon Tour?

The lagoon tours run all year, and the season decides more about your day than the month you book. Meteo-France Polynesie gives the Society Islands, Bora Bora among them, a cooler, drier season from May to October and a hot, humid rainy season from November to April, wettest in December and January. On any date, Rohivai Tours’ full day, Bora Bora: Full day Lagoon Safari & Lunch on a Motu - ST, needs favourable weather to run; it is from $169 a person (checked November 2026).

The short answer

If you can choose, May to October is the drier, less humid half of the year, and the safer bet for a day in the sun on the water. November to April is warmer and wetter, with the heaviest rain in December and January, yet in Tahiti Tourisme’s words locals and regular visitors prefer it, for greener mountains and more private stays. Whatever the month, keep a spare day in your stay: the trip runs only in favourable weather, and a free day lets you move it.

The two seasons

Meteo-France Polynesie describes two broad seasons for French Polynesia: November to April is the hot season of the austral summer, with higher humidity, and May to October the cool season of the austral winter, with lower humidity. For the Society archipelago the rainy season starts in November and ends in April, with heavy rain in the hot season and often light rain in the cool one; December and January are the wettest months. The split does not hold strictly for every island. The mean annual temperature at Faa’a, on Tahiti, is 26 °C.

Tahiti Tourisme puts the choice in two lines: some say the best time is the dry season, from May to October, while locals and regular travellers prefer November to April, for greener mountains and more private stays.

What the weather means for the day

A lagoon tour is a day on a boat and in the water, so wind, rain and sea state matter more than the air temperature. Rohivai Tours’ trips need favourable weather and a minimum number of travellers to run. On H2O Bora Bora's trip the itinerary can change with the weather and with where the animals are, and on Moana Adventure Tours' shark and snorkel safari the chance of turtles, dolphins, whales and manta rays depends on the weather and the time of year.

What to bring, in any season

On Rohivai Tours’ full day: sunscreen, beachwear, water shoes and a camera, with a towel and the snorkelling gear provided. Its half day adds a hat, sunglasses and biodegradable sunscreen to the list. Bring a light layer for the boat ride back in the cooler months, and for the rainy season a dry bag for your phone.
