When to go
Goto has two different seasonal answers.
Best overall window
General combines land tourism and locally published sea services.
Outside that window
A seasonal activity listing is not a weather guarantee.
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: More variable | Overall - Feb: More variable | Overall - Mar: Good | Overall - Apr: Good | Overall - May: Good | Overall - Jun: Good | Overall - Jul: Best | Overall - Aug: Best | Overall - Sep: Tradeoffs | Overall - Oct: Tradeoffs | Overall - Nov: More variable | Overall - Dec: More variable |
These do not replace the overall planner. Use them only if a specific animal or event is driving your trip dates.
