In Rio de Janeiro, a notable increase in humpback whale sightings has been observed. This surge is attributed to the species' recovery from the effects of commercial whaling. As a result, there is a growing interest in whale-watching trips in the area.

The humpback whales are seen off the coast of Rio de Janeiro during their annual migration. The demand for excursions to spot these marine creatures is accelerating.
