Moorea-Maiao in September

April through November brings trade winds that keep temperatures bearable and rain to a minimum. July and August see crowds from French school holidays - book accommodation early or pay premium prices. The shoulder months of April, May, October, and November offer the sweet spot of good weather and reasonable crowds. December through March brings cyclone season and humidity that makes you question life choices. But here's the thing - even wet season has its charms. Waterfalls rage, vegetation explodes in impossible greens, and you might have entire islands to yourself. Just pack good rain gear and flexible plans.
