Harmless. Go with a boat operator who keeps a respectful distance.

It is easy to forget, living in a beach town, that the water in front of you is the Pacific and that very large things move through it. Then a whale breaches off the headland and the whole beach goes quiet.

Where you’ll see it

Offshore along the whole coast, with the Gulf of Papagayo a reliable stretch. Boat trips run from Coco and the marinas in season. From land, the headlands at Ocotal and Hermosa give the best odds, and sport fishing boats see them constantly.

What to know

Costa Rica sits where the migration routes of two humpback populations overlap. Whales from the southern hemisphere come north to breed and calve in the warm water here from roughly August to October. Whales from the northern hemisphere come south for the same reason from roughly December to March. Mothers with calves keep to the quieter bays.

A good operator keeps the legal distance, cuts the engine when whales are close, and does not chase. Choose one that does, and you will see the whales behave like whales rather than like animals being followed.

Questions people ask about this one

When is whale season in Guanacaste?

Costa Rica is unusual in being visited by humpbacks from both hemispheres. Southern whales arrive roughly August to October, northern whales roughly December to March. Off the Papagayo peninsula that adds up to a good chance for much of the year, with the southern season usually the stronger one.

Can you see whales from Playas del Coco?

Boats out of Coco and the Papagayo marinas run whale trips in season and sightings are regular. From shore it is luck, but a breach seen from the beach at Ocotal or Hermosa is not unheard of.

Wondering what else is out there?

Ask me on the call. I'll tell you what actually shows up in a Coco garden, what to do about it, and the one guy everyone rings when there's a boa in the roof.
