When to go
Plan around two realities: sea state and season.
Best overall window
Drier weather, cooler nights, and steadier sea breezes often around 20 km/h. Water typically 21°C to 24°C.
Outside that window
Hotter and more humid with higher rainfall. Water can be 25°C to 27°C but storms and marine stingers are more likely.
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: Tradeoffs | Overall - Feb: Tradeoffs | Overall - Mar: Tradeoffs | 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: Tradeoffs |
These do not replace the overall planner. Use them only if a specific animal or event is driving your trip dates.
