When to go
The park defines Jan-Mar and Jul-Sep as relatively drier intervals, with Apr-Jun and Oct-Dec generally rainier.
Best overall window
No verified guaranteed open season, whale sighting rate, current microbiological water-quality profile, monthly sea-state averages or forward boat timetable.
Outside that window
Crossings and exposed sites can feel rougher in this stretch.
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.
