May and June
Go nowThe dry season starting, and the crowd not yet here
Warm, dry, low humidity and the water at its clearest, with the cyclone season formally over. Prices are below the July peak and the lagoon is quiet. The best value window of the year, and the one to take if you can choose freely.
September and October
Go nowStill dry, still clear, and the crowd gone
The far end of the dry season: reliable weather, excellent visibility for snorkelling and the northern-hemisphere summer holidays over. October is the last comfortable month before the wet season sets in. Often the cheapest good month here.
July and August
Worth it, butThe best weather and the fullest island
Dry, breezy and the coolest part of the year, which is exactly why it is peak season — European and American summer holidays, and the highest prices of the year. The Heiva festival falls in July and is the most interesting cultural event in Polynesia. Book far ahead.
April
Worth it, butThe wet season ending, and the risk falling
Rain eases through the month, humidity drops and prices are still low. The cyclone season formally runs to the end of April, so the risk is reduced rather than gone. A reasonable gamble late in the month.
November
Worth it, butHot, humid, cheap, and the season opening
The wet season begins and the cyclone window opens, though November is historically among its quieter months. Warm sea, low prices and afternoon rain. Worth insuring properly rather than avoiding outright.
December and January
Think twicePeak humidity and rain, with holiday prices on top
Hot, very humid and wet, in the middle of the cyclone season, while Christmas and New Year push prices back up regardless. You pay high-season rates for wet-season weather, which is the worst trade on this calendar.
February and March
Think twiceThe heart of the cyclone season
The wettest and most humid months and statistically the most active part of the cyclone window. Boat transfers and lagoon tours are cancelled in bad weather. Prices are the lowest of the year, and this is why.
