When to go
December-April is a practical first-choice travel season, not a promise of calm water.
Best overall window
Generally drier visitor weather. Continue checking daily marine conditions and holiday booking pressure.
Outside that window
Late-summer to autumn overlaps the climatological Atlantic tropical-cyclone peak. Trips still run, but storms can disrupt ferries, flights and water activity. Regional water is climatologically warmer, not necessarily clearer or safer.
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.
