When to visit Costa Rica for Manuel Antonio's beaches and wildlife, Arenal Volcano, Monteverde cloud forest, and Tortuguero's sea turtles — complete month-by-month seasonal guide for Costa Rica in 2026.
Best Time to Visit Costa Rica 2026: Complete Seasonal Guide
Costa Rica — 51,000 km² of Central America containing 6% of the world’s biodiversity — offers a genuine paradox: the dry season is universally recommended, but the “green season” (wet season) has compelling advantages for wildlife, photography, and budget travelers. The country’s geography creates multiple microclimates that complicate the simple dry/wet binary.
Costa Rica’s Two Seasons
Dry Season (December–April): The Recommended Window
December–April is the busiest and most universally comfortable period:
- Pacific Coast (Manuel Antonio, Tamarindo, Guanacaste): Essentially no rain; temperatures 28–33°C; beach conditions excellent
- Central Valley (San José, Alajuela): Pleasant 22–26°C; clear sky views of the volcanoes
- Arenal Volcano: The volcano is sometimes visible (Arenal is frequently cloud-covered even in the dry season)
- Monteverde: Dry season is less misty; the cloud forest is most accessible
Peak season warning: December–January and mid-February–mid-April are the busiest periods. Manuel Antonio National Park limits daily visitors to 1,500; book entrance tickets in advance (sinac.go.cr or the park’s website).
Green Season (May–November): The Other Case
Why some travelers prefer the green season:
- Wildlife: The wet season is nesting and birthing season for many species
- Tortuguero sea turtles: Green sea turtles nest July–October; leatherbacks March–April. This is the main attraction
- Prices: Hotels 30–50% cheaper; rental cars more available
- Crowds: Manuel Antonio, Tortuguero, and the Arenal area have significantly fewer visitors
- Photography: The dramatic afternoon storms create extraordinary light; the forest is most brilliantly green
The challenge: Afternoon rain (1–4 hours daily in the wet season) can limit outdoor activities. September–October is the rainiest; roads can flood; some eco-lodges operate reduced schedules.
By Destination
Manuel Antonio National Park
Best time: December–April for the most reliable weather and beach conditions.
Why Manuel Antonio is extraordinary: The park sits on a peninsula where primary rainforest descends to white-sand beaches — sloths hang in the trees above the beach towels, monkeys (howler, white-faced capuchin, squirrel monkey) raid picnic bags, scarlet macaws fly overhead, and coatis (raccoon relatives) are essentially endemic to the car park.
What to know:
- The park is closed on Tuesdays
- Daily visitor limit: 1,500 (book far in advance in high season)
- The coastal trail is 7km; most people see the beach in 4–5 hours
- Sloth spotting: Hire a park guide (licensed guides gather at the entrance). The guides’ scopes find sloths that invisible to the untrained eye
Arenal Volcano and La Fortuna
Best time: February–April (clear days) and July–August (slight clearing in the otherwise wet rainy season).
What Arenal offers: The 1,670m cone volcano (which erupted continuously from 1968 to 2010) rising above the Arenal Lake, with the La Fortuna waterfall (70m), the Mistico Arenal hanging bridges (jungle canopy walking), and hot springs (Tabacón, Baldi) heated by volcanic activity.
The cloud cover issue: Arenal is frequently cloud-covered — even in “dry” season. Statistically, February and March have the clearest days. The evening view from the hot springs when the cloud clears is extraordinary; book hot spring access for after 6pm when clouds occasionally lift.
Monteverde Cloud Forest Reserve
Best time: January–April (dryer, more accessible; fewer leeches on trails). The cloud forest is, by definition, always misty — the “dry season” here is simply less wet.
The cloud forest experience:
- The resplendent quetzal (the most spectacular bird in the Americas): Mating and nesting season February–May; the male’s 1-meter tail feathers are visible in the cloud forest canopy. This is the primary reason birders visit Monteverde
- Hanging bridges: The 3km suspended bridge trail (The Clouds Forest Sky Walk) traverses the canopy at 35m above the forest floor
- Ziplines: The Monteverde zipline circuit (13 cables, the longest in Central America) is the best adventure activity in Costa Rica
Tortuguero National Park
Best time for sea turtles: July–October for green sea turtles; March–April for leatherbacks.
What Tortuguero is: A canal-and-river system on the Caribbean coast (no roads access; arrival by boat or small plane only) with primary rainforest on either bank. The beach at night during nesting season — green turtles up to 150kg dragging themselves onto the beach to lay 100–130 eggs — is one of the most extraordinary wildlife experiences in the world.
What to know: Night turtle tours are guided only (protection of nesting turtles requires no flashlights, no camera flashes, quiet behavior, and licensed guides). Book guided tours through your lodge.

FAQ
Is Costa Rica safe? Relatively safe by Latin American standards. San José requires the standard urban precautions (don’t display phones and cameras, use registered taxis or Uber, avoid downtown at night). The tourist areas (Manuel Antonio, La Fortuna, Monteverde, Guanacaste) are very safe.
Do I need a 4WD car in Costa Rica? Yes — for any driving outside main highways. The roads to many eco-lodges and viewpoints are unpaved and rocky; rental companies recommend 4WD. A 4WD SUV is essential for the Monteverde road (which is unpaved and rough despite being the main tourist road).
How much does Costa Rica cost? Costa Rica is the most expensive destination in Central America. A comfortable mid-range budget is $150–200/day. Eco-lodges in the national parks are pricier than equivalent Southeast Asian accommodation; the trade-off is the wildlife density and the organization of the conservation areas.
