When to go
There are two defensible trip calendars here, not one universal best month.
Best overall window
Comfortable Weather.
Outside that window

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: Off | Overall - Feb: Off | Overall - Mar: Off | Overall - Apr: More variable | Overall - May: Best | Overall - Jun: Best | Overall - Jul: Best | Overall - Aug: Best | Overall - Sep: Best | Overall - Oct: More variable | Overall - Nov: Off | Overall - Dec: Off |
These do not replace the overall planner. Use them only if a specific animal or event is driving your trip dates.
