The passage of humpback whales has turned Ilhabela’s winter into one of the most special times to be at sea. The main season runs from May to August, with the highest concentration of records usually in June and July.
What is the best time?
Official city sources indicate a season from May to August, with sightings generally peaking in June and July. Because these are wild animals, there is no guarantee of an encounter on any specific day.
Why do humpback whales pass Ilhabela?
Humpback whales undertake a major migration between feeding areas in the cold waters of the South Atlantic and warmer breeding grounds along the Brazilian coast. Ilhabela lies along the route used by some of these animals.

In addition to humpback whales, the region records dolphins and other whale species. Bryde’s whales, for example, may occur year-round in southeastern Brazil.
Responsible whale watching
Encounters must follow rules for vessel approach and behavior. Trained operations and responsible conduct reduce disturbance and improve the quality of observation.
