When to go

Best time to visit Abrolhos Marine National Park

Abrolhos has two headline seasons.

Best overall window

Warmer water 24°C to 27°C, generally better visibility and more comfortable surface intervals.

Outside that window

Start of whale season and windier patterns; crossings can be uncomfortable and cancellations are more common.

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.

The archipelago is a key seabird habitat.

If you can only pick one window, choose based on your priority: clearest reef diving (DecMar) or whales (JulOct).

Apr to May, Nov: Mixed conditions and fewer crowds; good for flexible itineraries that can pivot between offshore and Timbebas.
Jun: Start of whale season and windier patterns; crossings can be uncomfortable and cancellations are more common.
