Whale and Dolphin Season in Costa Rica

When and Where to See Them?

Costa Rica is one of the most spectacular destinations in the world for whale and dolphin watching. Thanks to its strategic location between two oceans and rich marine biodiversity, thousands of visitors gather each year to observe these incredible marine mammals in their natural habitat. Whether you’re planning a boat tour, recreational diving, or simply ocean views from shore, this guide will help you understand when, where, and why to see whales and dolphins in Costa Rica.

  • When Is Whale Season in Costa Rica?

In Costa Rica, there are two main seasons for humpback whale watching.

Summer Season

Southern Pacific

Summer Season

July – October

This period is one of the best times to see humpback whales in the Southern Pacific (like in the Osa Peninsula and Drake Bay), where whales migrate from cold northern waters to reproduce, mate, and give birth.

Green season

Central & Northern Pacific

Green season

December – April

During this season, humpback whales return to the northern Pacific region, including Tamarindo, Flamingo and the Nicoya Peninsula, offering other excellent opportunities for sightings.

  • Top Places to See Whales and Dolphins

    Costa Rica offers many ideal spots for spotting these marine giants. In addition, many tours also combine whale watching, dolphin watching, and snorkeling in a single trip.

Bahía Drake

Southern Pacific

Renowned for abundant humpback whales and spotted dolphins.

Golfo Dulce

Southern Pacific

Protected waters perfect for calm viewing.

Tamarindo & Flamingo

Guanacaste

Great departure points for boat tours during peak season.

  • Which Dolphins Can You See in Costa Rica?

    Costa Rica is also an excellent destination for dolphin watching, including bottlenose dolphins, spotted dolphins, and common dolphins. These animals can be observed year-round, most frequently and abundantly on tours from Guanacaste and Drake Bay.

  • Humpback Whale Behavior and Migration

    Humpback whales migrate thousands of kilometers each year, moving from cold feeding grounds to warm waters to reproduce and give birth. During the seasonal months, it is common to see spectacular jumps, tail slaps on the surface, songs, and underwater vocalizations. Because of this, Costa Rica is one of the world's favorite destinations for marine ecotourism.
