When to go
The tourism climate guide supports year-round travel with April-May and September-October as the most balanced weather choices.
Best overall window
Official tourism climate guidance identifies the shoulder months as a warm and relatively dry balance. April still falls inside the regional cyclone season.
Outside that window
November transitions into the warmer season, while December-March is more humid and rainy; tropical cyclones are a regional seasonal possibility.
Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
