When To Go · Destination Guide
Ride the tides through the Tuamotus' most famous pelagic pass
When to go
Rangiroa is warm and diveable year-round, but May to October is the easiest overall window because it matches French Polynesia's drier season, lower humidity, and more reliable excursion weather.
Best overall window
Drier season, warm water near 27°C to 28°C, easier boat and topside planning.
Outside that window
November to April is warmer and wetter, so build flexibility into boat excursions and inter-island flights.
Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
The overall row stays visible so you can compare it against the currently selected scope.
| Scope | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Overall | Overall - Jan: Good | Overall - Feb: Good | Overall - Mar: Good | Overall - Apr: Good | Overall - May: Best | Overall - Jun: Best | Overall - Jul: Best | Overall - Aug: Best | Overall - Sep: Best | Overall - Oct: Best | Overall - Nov: Good | Overall - Dec: Good |
These do not replace the overall planner. Use them only if a specific animal or event is driving your trip dates.
