Guanacaste Rainy Season: Whale watching, Sea Turtles & Fishing Adventures

Costa Rica for Families – Whale Watching, Sea Turtles & Fishing Adventures during Tamarindo’s Secret Season

The Guanacaste, Costa Rica rainy season isn’t what you think. Sure, there are showers – mostly in the early morning, early afternoon, or overnight – but that just means the region comes alive in ways you won’t see during the dry season.

Picture this: humpback whales breaching offshore. Sea turtles nesting by moonlight. Rivers running strong for tubing and waterfalls. And the best part? You can experience it all without the high-season crowds or prices.

Welcome to Costa Rica’s secret season: a green, vibrant time of year that turns Tamarindo into a family-friendly paradise full of nature, adventure, and value. With plenty of Costa Rica beach house rentals to choose from, it's the perfect time to plan a reunion, a family vacation, or a getaway with friends.

Why Travel in the Guanacaste, Costa Rica Rainy Season?

From late May through early November, the landscape transforms. Everything is greener, the air feels fresher, and the sunsets are some of the best you’ll ever see. Best of all, Tamarindo gets less rain than other parts of the country, so you can still spend your days at the beach, in the water, or out on the trails.

Other benefits of visiting in the rainy season:

Lower prices on Costa Rica beach house rentals, tours, and flights
Fewer crowds, even at popular spots
More wildlife, as many species are more active in the wetter months
Family-friendly adventure, like tubing, zip-lining, hiking, and fishing

For families traveling on a budget or anyone looking to stretch their vacation time a little longer, the Guanacaste, Costa Rica rainy season is a hidden gem.

Whale Watching Season: Ocean Giants Up Close

From July through October, Tamarindo becomes one of the best places in Costa Rica to spot southern humpback whales. These gentle giants migrate thousands of miles from Antarctica to give birth and raise their calves in the calm, warm Pacific waters.

You can often spot whales breaching from the beach, but for a closer look, hop on a catamaran tour or private boat with a local guide. These family-friendly excursions often include dolphin sightings, snorkeling, snacks, and fun for kids of all ages.

Top Species to Spot:

Southern Humpback Whales (July to October)
Bottlenose Dolphins (year-round)
Spinner Dolphins (year-round, often travel in playful pods)

Sea Turtle Nesting: A Magical Nighttime Experience

There’s nothing quite like watching a sea turtle come ashore to nest. It’s quiet. It’s powerful. And it’s something your family will never forget. The Tamarindo area is close to several protected turtle nesting beaches, where you can take guided night tours to observe turtles in their natural habitat.

Depending on the time of year, you might even see tiny hatchlings making their dash for the sea!

Sea Turtles Near Tamarindo:

Olive Ridley Turtles at Playa Ostional (arribadas: June–November)
Leatherback Turtles at Playa Grande (October–February)
Green & Hawksbill Turtles in smaller numbers year-round
