Bora Bora · Month comparison
January vs May
May ranks #1 overall vs January at #11. Dry season begins — the lagoon turns its iconic turquoise, temperatures are pleasant, and the humpback whale season opens.
January
#11 of 12 months
Worth considering
Wet season in full force — heavy rain alternates with brilliant sunshine, prices are lower, and the lagoon is warm and calm.
- ↑Bora Bora's lagoon is year-round warm (29°C), and even the wet season delivers clear, sunny periods between the tropical downpours; the underwater visibility in the lagoon remains excellent regardless of surface rain, and the black-tip reef sharks, manta rays, and stingrays in the Bora Bora lagoon are present every month
- ↑January prices are significantly lower than the July–September dry season peak — overwater bungalows at the Four Seasons, St. Regis, and Conrad can be 30–40% cheaper than their July rates; the lagoon quality is unchanged
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

January trade-offs
- ↓January is the heart of the wet season — 280mm of rain over the month arrives in heavy tropical downpours rather than persistent drizzle; typically 1–3 hours of intense rain per day followed by sunshine, but on bad days the cloud cover can suppress the famous turquoise lagoon colour
- ↓Cyclone risk in the South Pacific peaks between November and April — while direct cyclone hits on Bora Bora are rare (the island sits at the northern edge of the cyclone belt), tropical systems can bring sustained cloud, swell, and disrupted resort operations for 3–7 days; check seasonal forecasts and buy cancellation insurance
- ↓The inter-island Air Tahiti connections (the only way to reach Bora Bora from Tahiti's Faa'a airport) can be temporarily suspended during severe weather events; buffer time before international departure is essential in the wet season
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
