Bora Bora · Month comparison
November vs May
May ranks #1 overall vs November at #10. Dry season begins — the lagoon turns its iconic turquoise, temperatures are pleasant, and the humpback whale season opens.
November
#10 of 12 months
Worth considering
Wet season arrival — heavy tropical rain returns with cyclone risk, but the lagoon is warm and manta ray season begins.
- ↑Manta ray season opens in November: the Bora Bora lagoon cleaning stations (where manta rays hover while cleaner wrasse remove parasites) are visited most reliably in the wet season months (November–March); a manta ray snorkelling encounter — hovering above a 4-metre wingspan gliding through the turquoise water — is one of the finest lagoon experiences available
- ↑November is still early enough in the wet season that extended rain events are less frequent than December–February; many days deliver sunshine for 6–7 hours with tropical showers in the late afternoon
May
#1 of 12 months
Best match
Dry season begins — the lagoon turns its iconic turquoise, temperatures are pleasant, and the humpback whale season opens.
- ↑May marks the beginning of Bora Bora's dry season: rainfall drops to 90mm, the trade winds arrive from the southeast bringing clear skies and a comfortable breeze that takes the edge off the tropical heat, and the lagoon achieves the vivid turquoise colour that defines Bora Bora in the global imagination — the combination of the coral sand motu, the turquoise lagoon, and Mount Otemanu in clear sky is at its best from May onwards
- ↑Humpback whale season fully opens in May — whales arrive from their Antarctic feeding grounds and use French Polynesia's warm waters for breeding and calving; boat tours from the Bora Bora pier offer encounters (the whales approach the boats out of curiosity), and snorkelling alongside a 15-metre humpback is among the most singular wildlife experiences available in the Pacific

November trade-offs
- ↓At 175mm, November rain is substantial — heavy tropical downpours become a daily feature; the famous turquoise lagoon colour is suppressed on overcast days
- ↓Cyclone season opens in November — while the probability of a direct cyclone hit in any given November is low, the risk exists and travel insurance covering weather disruption is non-optional
- ↓Some resort activities (kayak circumnavigation of the main island, longer motu excursions) become weather-dependent in November in a way that July excursions are not
May trade-offs
- ↓Some residual rainfall remains in May (90mm) — the dry season in Bora Bora is never bone-dry; brief tropical showers are still possible daily, though they typically last 30 minutes and are followed by sunshine
- ↓Crowds begin building in May as European visitors target the shoulder season and Tahiti-based tour packages ramp up; the best overwater bungalow categories fill up 3–4 months in advance for May stays
- ↓Temperatures drop slightly from the wet season highs — 28°C days with the trade wind chill create what is subjectively the most comfortable temperature range of the year, but those who equate tropical with very hot may find May slightly cool for extended lagoon swimming
