A Seasonal Guide to Nesting, Hatching, and Planning Your Visit

On Costa Rica’s northern Caribbean coast, Tortuguero is synonymous with sea turtles. This remote canal village, accessible only by boat or small plane, borders Tortuguero National Park — one of the most important green turtle nesting sites in the Western Hemisphere.

If your goal is to witness turtle nesting or hatchlings making their way to the sea, timing matters. Different species arrive at different times of year, and Tortuguero’s Caribbean climate follows a pattern distinct from Costa Rica’s Pacific coast.

Below is a detailed, practical breakdown of when to visit — and what to expect.

Understanding Turtle Nesting Cycles in Tortuguero

Tortuguero hosts several sea turtle species, but three are most relevant to visitors: green turtles, leatherbacks, and hawksbills.

Green Turtles (Chelonia mydas)

Peak nesting: July through October

This is Tortuguero’s most famous nesting event. Thousands of green turtles come ashore during these months, with August and September typically the highest-activity period.

If you want the best odds of witnessing a nesting turtle at night, late July through mid-September is generally ideal. Hatchlings often emerge about 60 days after eggs are laid, meaning September through October can also offer hatchling sightings.

Leatherback Turtles (Dermochelys coriacea)

Nesting: March through June

Leatherbacks — the largest sea turtles in the world — arrive earlier in the year. While nesting numbers are lower than those of green turtles, seeing a leatherback is an extraordinary experience.

April and May are often the strongest months for leatherback activity.

Hawksbill Turtles (Eretmochelys imbricata)

Nesting: April through October (sporadic)

Hawksbills nest in smaller numbers, and sightings are less predictable. However, they overlap with green turtle season.

The Best Overall Months for Turtle Viewing

If you are planning a trip specifically around turtle nesting in Tortuguero:

  • August and September: Highest probability for green turtle nesting.
  • April and May: Best window for leatherback turtles.
  • September and October: Excellent for both nesting and hatchlings.

It’s important to note that turtle tours are highly regulated. Night tours must be conducted with certified guides inside the park, and flash photography is strictly prohibited to protect wildlife.

Where to Stay for Easy Turtle Tour Access

Most lodges in Tortuguero arrange certified turtle tours during nesting season.

For convenience and organized packages, many travelers choose jungle lodges such as:

For a more boutique, quieter experience with a strong conservation focus, Tortuga Lodge & Gardens is often considered one of the most refined stays in the region.

These lodges typically include guided turtle tours during nesting season as part of multi-night packages.

If staying in the village rather than a package lodge, confirm that your accommodation partners with licensed guides.

What If You Visit Outside Turtle Season?

Tortuguero is much more than turtle nesting.

Even outside peak turtle months, the region offers:

  • Early-morning canal boat tours for wildlife spotting
  • Kayaking through rainforest waterways
  • Hiking trails within Tortuguero National Park
  • Birdwatching (toucan, heron, kingfisher sightings are common)
  • Cultural walks through the village

Wildlife viewing in Tortuguero is excellent year-round. Monkeys, caimans, sloths, and tropical birds are present year-round.

Seasonal Travel Planning Tips

Tortuguero’s climate follows Caribbean weather patterns, not Pacific ones.

  • September and October: Often surprisingly sunny on the Caribbean side — excellent for turtle season.
  • December through February: Rainier months, though wildlife activity remains strong.
  • March through May: Good combination of leatherback nesting and relatively stable weather.

Because turtle tours take place at night, be prepared for humidity, light rain, and muddy conditions year-round.

Pack essentials such as:

  • Lightweight rain jacket
  • Closed-toe shoes suitable for sand
  • Neutral or dark clothing (required for night tours)
  • Mosquito repellent

Booking is strongly recommended during August and September, as lodges fill quickly.

Is Turtle Season Worth Planning Around?

If witnessing nesting sea turtles is a life goal, then yes — plan around it.

Tortuguero, during peak green turtle season, is one of the most powerful wildlife experiences in Central America. Watching a 300-pound turtle emerge from the sea under starlight is unforgettable.

However, if you are flexible with wildlife goals, Tortuguero’s canals and rainforest make it worthwhile year-round.

The key is to align expectations with seasonality. Choose your species, confirm nesting windows, book certified tours, and allow enough nights (at least two or three) to increase your chances.

With thoughtful timing, Tortuguero offers one of the most extraordinary wildlife encounters in Costa Rica.
