Imagine the thrill of spotting a 40-ton humpback whale breach from calm, emerald waters with rainforest-covered mountains rising in the distance. In Costa Rica’s Golfo Dulce, this isn’t just possible—it’s part of a remarkable annual migration that draws travelers and marine biologists from around the world. Between July and October, southern humpback whales arrive in this tropical fjord to give birth and nurture their young in some of the most protected and biodiverse waters in Central America. If you’re searching for one of the best places to experience humpback whale watching in Costa Rica, Golfo Dulce offers an encounter like no other.
Why Do Humpback Whales Come to Golfo Dulce?
Golfo Dulce is one of only a few tropical fjords in the world—and its unique geography creates the perfect nursery for humpback whales. Every year, two different populations of humpbacks visit Costa Rica’s Pacific waters:
- Northern Hemisphere whales arrive from Alaska and California between December and April
- Southern Hemisphere whales migrate from Antarctica between July and October
During these months, the calm, warm waters of Golfo Dulce become a safe haven where whales mate, give birth, and nurse their calves. This is a critical stage in the life cycle of the species, and observing these majestic creatures in such an intimate setting is a privilege few destinations can offer.

Why Golfo Dulce Is One of the Best Places in the World to See Whales
Golfo Dulce isn’t just scenic—it’s scientifically significant. This tropical fjord is one of only four in the world, and one of the rare places where humpback whales come incredibly close to shore to rest, mate, and raise their young. Its unique combination of warm, calm waters, depth, and low salinity creates the perfect sanctuary for these gentle giants.
During the migration seasons, especially from July to October, visitors have the rare opportunity to witness an array of whale behaviors that go far beyond simple sightings. You may see whales:
- Breaching – launching their entire bodies out of the water
- Slapping their tails or flippers – possibly to communicate or attract mates
- Spy-hopping – rising vertically to peer above the water’s surface
- Swimming with calves, nursing or teaching them survival behaviors
These awe-inspiring displays highlight the humpback whale’s incredible agility, intelligence, and social nature.
What truly sets whale watching in Golfo Dulce apart is the serenity and respect that defines the experience. Unlike more trafficked areas, the limited number of boats and conservation-minded operators ensure that marine wildlife encounters remain sustainable and non-intrusive. At Nicuesa, you’ll feel like you’re part of a rare and privileged moment—not a crowd.
Seeing a 40-ton whale breach against a rainforest backdrop isn’t just a photo opportunity—it’s a humbling reminder of our connection to the wild.
