Vaitape in June

April through October gives you the best weather, but here's what the brochures won't tell you: even the 'dry' season gets 10 inches of rain monthly. November through March brings cyclone season and humidity that makes you question life choices. But those months also bring 30% lower hotel rates and fewer crowds. The sweet spot? May and September. You get warm lagoon temperatures, minimal rain, and trade winds that keep the bugs away. Avoid July and August unless you enjoy sharing paradise with every honeymooner in the Northern Hemisphere. Water temperature stays around 80°F year-round, so that's never a concern. Just know that 'partly cloudy' in Bora Bora means dramatic cloud formations that actually make the photos better.
