When to go
May to October is the broad diving-led travel window.
Best overall window
The broad published diving window. Plan around the daily sea forecast; July and August add stronger heat and holiday demand, while the ends of the window need more thermal and weather flexibility.
Outside that window
Keep a land-first itinerary and arrange water activities only after checking operator availability and conditions. This is not a regionwide seasonal closure.
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.
