Protected Pacific reefs by day, Osa rainforest by night.
When to go
For a conventional Caño day-boat scuba or snorkel trip with a Drake Bay land base, start with January through April.
Best overall window
Season labels are broad planning guidance, not a promise of daily marine safety, visibility or wildlife.
Outside that window
South Pacific rainfall is normally high and disruptions more consequential. Short-range conditions may differ from the climatological pattern.
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.
