Quick Answer: Best Times at a Glance
For most travelers, the best time to visit Costa Rica is the dry season, from mid-December to April—when weather is sunniest but crowds and prices peak, especially around Christmas/New Year and Semana Santa. If you prefer lush scenery, solitude, or lower costs, hedge months like late November to early December and May to August offer more balanced conditions. The Caribbean coast, including Puerto Viejo and Tortuguero, often sees its best weather when the Pacific is wettest. Your ideal month depends on which matters most: weather reliability, cost, crowd levels, or access to specific activities.
– Best weather: Mid-December to April (dry season, Pacific)
– Fewer crowds & better value: May–early June and late November–early December (“hedge” months)
– Greenest landscapes: May–September (early wet season)
– Caribbean best: September–October (driest here, wettest in the west)
– Hardest months for outdoor travel: October (Pacific slope), late September–November (remote roads/trails)
How Costa Rica’s Seasons Work
Costa Rica pivots around two distinct seasons. The dry season (“verano”) runs mid-December to April, bringing consistent sunshine to the Pacific coast, Nicoya/Guanacaste, and most interior regions. The rainy season (“invierno”), May through November, sees heavier showers, particularly in the afternoons—transforming the landscape but complicating transport and trail conditions, especially in rural or forested parks.
Hedge months—late November to early December, and May to early August—straddle these extremes. They often combine passable roads, moderate prices, and manageable rains. Importantly, Caribbean destinations like Puerto Viejo, Cahuita, and Tortuguero follow a different rhythm: their driest periods are February–April and September–October, the inverse of the Pacific.
Month-by-Month: Weather, Crowds, Costs, Best Regions
December
– Mid-December marks the start of the dry season; early December (pre-holidays) is uncrowded but weather still transitioning.
– Christmas/New Year is peak demand; book well ahead.

February
– Reliable sun; lowest rainfall of the year in most places.
– Caribbean starts a drier window (Puerto Viejo, Cahuita).
– Expect continued high demand in Pacific/urban areas.

July
– “Little summer”/veranillo in Pacific: brief drier spell.
– Crowd levels low outside local school holidays.
– Caribbean still variable, but waterfalls and forests vibrant.
August
– Continued moderate rain, less predictable.

October
– Wettest month overall for Pacific and mountain regions: landslides, transport interruptions possible.
– Avoid Mt. Chirripó, Corcovado, and Rio Celeste this month unless prepared for mud, closures, or washed-out routes.
– Driest for the Caribbean coast.
November
– Early: still wet, unpredictable.
– Late: drying begins, especially north and central Pacific.
– Hedge window: lush scenery, reasonable prices, less congestion.
– Further south, access may still be limited.
Region-by-Region Timing
Pacific Coast (Guanacaste, Nicoya, Central Pacific)
– Dry: December–April. Peak beaches, best trail access, but high prices.
– Rainy: May–November, save for brief dry sparks (veranillo) in July.
– Shoulder: late November and early December for bargains and manageable weather.
Osa Peninsula & Corcovado
– Serious rainfall May–November; many lodges close September–October.
– Best: January–April for hiking, wildlife, and beach camping.
– May or early December for solitude with only modest rain if you plan route carefully.
Central Highlands & Mt. Chirripó
– Dry season critical for multi-day treks: January–April; permits for Mt. Chirripó are limited year-round.
– Rain turns mountain routes muddy and sometimes treacherous June–November.
Caribbean (Puerto Viejo, Cahuita, Tortuguero)
– Driest: February–April and September–October.
– Wettest: June–July are mixed, but the winter sees clear periods when Pacific is drenched.
– Excellent for wildlife September–October (turtle nesting, birdwatching).
How Seasons Affect Major Activities & Attractions
Hiking (Mt. Chirripó, national park trails)
– Dry season (Jan–April) insures passable trails.
– Rainy months mean mud, closed sections—have flexibility.
Waterfalls (Rio Celeste, La Fortuna)
– Rainy season brings volume and drama, but water clarity (especially Rio Celeste) drops after heavy rain.
Surfing
– Pacific peaks during the wet season (May–October), though surf travelers should expect some interruptions.
Wildlife & Birdwatching
– Wildlife is easier near water sources in dry season.
– Turtle nesting: July–October in Tortuguero.
– Most birds visible year-round, but wet season brings migratory and breeding influxes.
Snorkeling/Diving
– Caribbean best in September–October (clearest water).
– Pacific waters colder with reduced visibility during rains.
Practical Travel Tips for Costa Rica: Booking, Roads and Packing
Booking Accommodation and Rental Cars
- Dry season: Reserve accommodation and rental cars months ahead, especially around Christmas, New Year and Semana Santa.
Driving in the Rainy Season
- Rainy season: a 4×4 is strongly recommended for Osa, Corcovado, Rio Celeste and anywhere off paved highways. Landslides and muddy tracks are possible.
Roads, Domestic Flights and Trail Access
- Roads to remote parks such as Osa, Monteverde and Rio Celeste can become difficult or temporarily impassable during peak rains.
- Expect some trail closures during the late rainy season, especially in mountain parks.
What to Pack for Costa Rica
- Pack light layers year-round, rain gear outside the peak dry months, and waterproof shoes for hiking between May and November.
Best Time of Day for Tours
- Schedule key tours and park entries in the morning, as rain often arrives after 2pm.
Costa Rica Holiday Calendar: When to Book
Christmas and New Year
- Mid-December to early January is one of the busiest periods. Book 6 to 12 months ahead for the best lodges, rental cars and tours.
Semana Santa
- Holy Week, usually in March or April, creates another major spike in demand. Accommodation and car rentals can sell out quickly.
July Little Summer
- July can bring a short drier spell on the Pacific side. There is some local demand, but it rarely sells out like Christmas or Semana Santa.
Turtle Nesting Season in Tortuguero
- Turtle nesting season runs from July to October. Lodges can fill quickly at peak times, especially on weekends.
How to Choose the Best Time to Visit Costa Rica
Best Months for Weather
- January to March are usually the best months for reliable weather on the Pacific coast and in the interior.
Best Months for Lower Prices and Fewer Crowds
- May to early June and late November to mid-December offer a good balance between lower prices, fewer visitors and manageable weather.
Best Months for Green Landscapes and Waterfalls
- Late May to July is ideal for lush scenery and powerful waterfalls, although trails can be muddy.
Best Months for the Caribbean Coast
- September to October and February to April are often the best periods for Puerto Viejo, Cahuita and Tortuguero.
Best Months for Wildlife
- Dry season is good for spotting animals near water sources. September and October are excellent for turtle nesting on the Caribbean coast.
Months to Avoid
- Avoid October on the Pacific coast if you want reliable road conditions and outdoor activities.
- Avoid mid-December and Semana Santa unless you book far in advance.
