Whale Watching in Costa Rica: Season, Best Places & How to Plan Your Trip
Costa Rica is one of the few places on Earth where humpback whales from two different hemispheres converge. Here’s how to be there when they arrive.
Humpback whale watching in Costa Rica is one of the most extraordinary wildlife experiences in the Western Hemisphere — and most visitors don’t even know it’s possible. While everyone talks about sloths in Manuel Antonio and sea turtles in Tortuguero, thousands of humpback whales quietly arrive along Costa Rica’s Pacific coast every year, from two different corners of the world. The country is one of only a handful of destinations where Southern and Northern Hemisphere humpbacks both pass through the same waters, making it home to the longest humpback whale watching season in the world. If you’ve never considered Costa Rica for whale watching, this guide will change your mind.
When Is Whale Watching Season in Costa Rica?
Costa Rica’s humpback whale watching season runs in two distinct windows each year. The Southern Hemisphere population travels north from Antarctica and arrives along the South Pacific coast from late July through mid-October. The Northern Hemisphere population comes down from Alaska and is present from December through mid-March. The town of Uvita, on the South Pacific coast, is one of the only places in the world where both populations congregate in the same bay — which is exactly why Marino Ballena National Park was created specifically to protect these waters.
The best months overall for near-daily humpback sightings are August and September — when Southern Hemisphere whales are at peak activity, nursing calves and practicing breaching. February is the standout month for the Northern Hemisphere window. If your Costa Rica trip falls in July, October, December, or March, you still have a strong chance of sightings, just not quite the density of peak season.
| Season | Months | Origin | Best Months |
|---|---|---|---|
| Southern Hemisphere | Late July – mid-October | Antarctica | August & September |
| Northern Hemisphere | December – mid-March | Alaska | January & February |
What Whales Will You See in Costa Rica?
Humpback whales are by far the most commonly seen species — and they put on a show. Adults reach 40–50 feet in length, and during mating and nursing season you’re likely to spot mothers with calves, breaching (full-body jumps out of the water), fin slapping, and the iconic tail flukes disappearing below the surface. Calves are remarkably playful and will often practice breaching repeatedly while the boat watches.
Beyond humpbacks, Bryde’s whales are occasionally spotted in Costa Rica’s Pacific waters. Pilot whales — technically the second-largest oceanic dolphin — are possible sightings. Orcas have been reported but are rare. On most whale watching tours, you’ll also encounter bottlenose dolphins and spinner dolphins, which frequently travel alongside the boats.
The Best Places for Whale Watching in Costa Rica
Not all of Costa Rica’s coastline is equally productive for whale watching. The South Pacific coast — particularly the stretch from Uvita down through the Osa Peninsula — is where the largest concentrations occur. Here’s how the main locations compare:
Uvita & Marino Ballena National Park — The Best Spot in the Country
Uvita is the undisputed capital of whale watching in Costa Rica. Marino Ballena National Park was established specifically to protect the rich marine life in these waters — and it’s named after the whale (“ballena” in Spanish). The park’s most famous feature is a natural sandbar shaped exactly like a whale’s tail, which extends into the Pacific at low tide. From July through October and again December through March, dedicated whale watching tours depart daily from the Uvita pier. Both hemispheres’ populations use these same waters to nurse calves and breed, making it the single most productive location in the country for year-round sightings.
Drake Bay & the Osa Peninsula — The Most Exclusive Experience
Drake Bay sits on the northern tip of the Osa Peninsula, one of the most biodiverse places on the planet. The Golfo Dulce — the warm, protected gulf along the Osa’s eastern edge — is where more humpbacks from both migrations come to birth and nurse their calves than almost anywhere else in Costa Rica. Crucially, it sees a fraction of the boat traffic of Uvita, making for a more intimate and less interrupted experience. Drake Bay is accessible only by boat or small plane — no roads in — which means the visitors who get there are serious, and the wildlife is correspondingly more relaxed around boats.
If you’re building a custom Costa Rica itinerary that includes the Osa Peninsula, work a whale watching excursion into your Drake Bay days. It’s one of the most compelling reasons to include this remote region in your trip.
Manuel Antonio — A Good Add-On During Peak Season
Manuel Antonio isn’t the top pick for whale watching, but during August and September — the absolute peak of the Southern Hemisphere season — humpbacks are spotted from catamaran and sailing tours departing Quepos. If your itinerary already includes Manuel Antonio and you’re visiting during those two months, it’s worth booking a morning sailing tour with whale watching in mind. That said, for the best odds, Uvita is only about an hour south — and well worth the short additional drive.
Gulf of Papagayo & Guanacaste — Possible on Sailing Tours
The Gulf of Papagayo in Guanacaste sees humpbacks during the July–September window. There are no dedicated whale watching tours here — but if you’re on a sailing, snorkeling, or beach-hopping excursion during those months, sightings are genuinely common. Tamarindo and Flamingo sailing operators report whale encounters regularly in August and September.
How to Plan a Whale Watching Trip with CRDA
The logistics of building whale watching into a Costa Rica trip depend heavily on your other destinations and travel dates. A custom itinerary from Costa Rica Dream Adventures solves this puzzle the way a search engine can’t: by knowing the actual conditions on the ground, the seasonal windows by region, and which lodges are close enough to the water for early morning departures.
A few itinerary structures that work particularly well for whale watching:
The Classic South Pacific Route (July–October): San José → Arenal (2–3 nights) → Manuel Antonio (2 nights) → Uvita/Dominical (1–2 nights) → San José or departure. This gives you a full whale watching day in Uvita during the Southern Hemisphere peak, with private transfers between each destination.
The Osa Deep Dive (August–September): San José → Drake Bay or Puerto Jiménez/Osa Peninsula (3–4 nights) → Manuel Antonio (2 nights) → San José. Drake Bay is the centerpiece here — whale and dolphin watching, Corcovado National Park day hikes, and the Golfo Dulce ecosystem. This is for travelers who want to go somewhere most Costa Rica visitors never reach.
Short Trip / Whale-Focused (5–6 days, August or September): San José → Manuel Antonio (2 nights) → Uvita (2 nights) → San José. Compact and effective. Morning whale watching tour in Uvita, a day in Manuel Antonio National Park, private transfers throughout.
Your CRDA travel specialist will build the itinerary around the specific dates you’re traveling — including which excursions make sense based on the current season — and will arrange the private transfers, lodge bookings, and tour operators on your behalf. You just need to show up.
Practical Tips for Whale Watching in Costa Rica
Take anti-nausea medication if you’re prone to motion sickness. Whale watching boats head into open Pacific swells, and the combination of rocking and looking down at a camera is a reliable recipe for seasickness. Over-the-counter options like Dramamine or prescription scopolamine patches work well — take them an hour before departure.
Bring a good camera with a long lens. Whales breach unpredictably and at distance. A 200–400mm zoom lens gives you the best chance of capturing the moment. Your phone is fine for the experience itself, but won’t get the shots you’re imagining from the dock.
Book a private tour if possible. On shared group tours, the boat follows a set route and schedule regardless of where the whales are. Private boats can communicate via radio with other captains and change course in real time when whales are spotted nearby. At CRDA, private excursions are standard — you’re never sharing your transfer van, and you don’t need to share your whale watching boat either.
Nature is unpredictable — choose the right window. Even in peak season, sightings are not guaranteed. August and September give you the best odds by a significant margin. If seeing humpbacks is the centerpiece of your trip (not just a nice bonus), build your travel dates around those two months.
Swimming with or touching whales is not permitted in Costa Rica. The country takes marine wildlife protection seriously. Tours keep a respectful distance and the experience is entirely observational — which, when a 40-foot whale breaches ten yards from your boat, turns out to be more than enough.
Frequently Asked Questions About Whale Watching in Costa Rica
When is the best time for whale watching in Costa Rica?
The best months for humpback whale watching in Costa Rica are August and September, when the Southern Hemisphere population is at peak density and near-daily sightings are common. A secondary window runs December through mid-March for the Northern Hemisphere population, with February being the standout month. Uvita and Drake Bay offer whale watching during both windows.
Where is the best place to go whale watching in Costa Rica?
Uvita, on the South Pacific coast, is widely considered the best place for whale watching in Costa Rica. Marino Ballena National Park protects the waters where both hemispheres’ humpback populations congregate. Drake Bay in the Osa Peninsula is a close second — less busy, with equally exceptional sightings. Manuel Antonio is possible in August and September if you’re already in the area.
What whales can you see in Costa Rica?
Humpback whales are by far the most commonly sighted species. Bryde’s whales and pilot whales are occasionally seen. Orcas have been reported but are rare. Bottlenose dolphins and spinner dolphins are very common on whale watching tours and frequently accompany the boats.
How long is Costa Rica’s humpback whale season?
Costa Rica has the longest humpback whale season in the world. Combined, the Southern Hemisphere window (late July–mid-October) and the Northern Hemisphere window (December–mid-March) mean whales are present for more than six months of the year. The town of Uvita is one of the only places on Earth where both populations use the same waters.
Can I include whale watching in a custom Costa Rica itinerary?
Yes — and it integrates naturally into a South Pacific routing. Uvita pairs well with Manuel Antonio (about an hour north) or as a southern stop before or after the Osa Peninsula. Costa Rica Dream Adventures will build whale watching into your custom itinerary based on your travel dates, arranging private transfers, lodge stays near the water, and the excursion itself. The free custom quote process starts at the link below.
Is whale watching in Costa Rica good for families?
Yes — children tend to be completely riveted by humpback sightings. The main consideration is the open-ocean boat ride, which can cause motion sickness in younger kids. Pack children’s Dramamine and choose morning departures when seas are calmer. The experience of watching a 40-ton animal breach out of the ocean a few dozen yards from the boat is something most kids remember for years.
