Lagoon wrecks, reef walls, a dramatic Grotto and an island worth exploring above water.
When to go
For a general mixed-group trip, December through June is the island's traditional drier period, with January through April a practical core.
Best overall window
Historical climate windows only.
Outside that window
Warmer/rainier planning period with greater typhoon and route-disruption exposure. Activities may still run on good days.
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.

These do not replace the overall planner. Use them only if a specific animal or event is driving your trip dates.
