When to go
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.
