Quick Guide – Best Times to Visit Costa Rica by Traveler Type
Best for Nature & Wildlife Lovers
The green season from July to October is ideal for wildlife enthusiasts. This period offers lush landscapes and the highest activity for whales (July–October migrations) and sea turtles (Pacific olive ridley nesting peaks December–February; green turtles on the Caribbean coast in July–October). Birding is excellent year-round, with 900+ species and the best visibility in the dry season.
Best for Adventure Seekers
January through April is optimal for hiking, volcano visits, and exploring national parks. Trails remain stable and dry, rivers are ideal for rafting after May rains, and surf conditions are consistent on both coasts from May to November. The “little summer” in July and August also opens clear adventure windows amid the green season.
Best for Beach Vacations
December to March offers sunny skies, calm seas, and fewer rainy days across Pacific beaches and the Nicoya Peninsula. Caribbean beaches remain warm year-round but have more rain. The dry season (6–9 rain days/month, water temperatures at 27–28°C) is perfect for sun-seekers and families.
Best for Budget Travelers
Traveling in the shoulder (May, November) or green season (June–October) means savings of 30–50% on accommodation and activities compared to the dry season. While rain increases, mornings often remain clear and crowds are minimal, providing excellent value.
Costa Rica Climate Explained: Seasons, Microclimates, and What to Expect in 2026
Overview of Costa Rica’s Dry and Green Seasons
The dry season, running December through April, features minimal rainfall (6–56mm/month) and average highs of 23–25°C. This is peak travel period, attracting up to 80% of annual visitors. The green season (May–November) brings higher rainfall (155–372mm/month), vivid vegetation, and spectacular biodiversity, with mornings usually clear and afternoons rainy.
The “Little Summer” (Veranillo): July & August Insights
During July and August, a brief meteorological window called ‘Veranillo’ yields drier, sunnier weather across most of Costa Rica—even during the wet season. Expect lower rainfall and increased opportunities for hiking, surfing, and wildlife spotting, especially on the Pacific coast.
Regional Differences: Pacific vs. Caribbean Weather
- Pacific Coast: Warm and sunny in the north during dry season (0–2 inches rain Dec–Mar), heavier rains from May onward. Monthly highs between 24–25°C, with sea temps 27–28°C.
- Caribbean Coast: Rain falls year-round (6–27 inches/month); best conditions in September and October with fewer storms.
- Central Valley & Highlands: Mild “spring-like” climate; 70–75°F year-round; fog and cool nights common at higher elevations.
Month-by-Month Breakdown: When to Go for the Best Experience
December to April: The Classic Dry Peak
Minimal rainfall (6–56mm/month), 23–25°C highs, and extensive sunshine (7 hours per day) define this period. It’s ideal for all outdoor activities, but expect crowded attractions and premium pricing. Popular locations like Manuel Antonio and Arenal fill quickly—book in advance.
May & November: The Underrated Shoulder Seasons
Transition months with moderate rain (155–261mm/month), lower visitor numbers, and significant discounts. Mornings stay clear, making it an excellent compromise between price and experience. These are top picks for budget-conscious travelers and eco-tourists.
June to October: Green Season Adventures & Secret Weather Windows
Cloud forests and rainforests flourish, with dramatic increases in biodiversity and green landscapes. Rain peaks in September and October (up to 372mm/month), but savvy travelers enjoy less crowded parks, whale watching, and “little summer” clear periods in July–August.
Local Festivals & Events by Month (with 2026 Dates)
- January: Fiestas Palmares (mid-Jan), lively rodeo and concerts
- March: Oxcart Festival, Santa Cruz (early March)
- June: Mango Festival, Pérez Zeledón
- August 2: Virgen de los Ángeles Pilgrimage
- December: Holiday markets and Christmas festivities
Top Activities and the Perfect Time for Each
Surfing & Beach Days
May to November offers the most consistent waves for surfers, while December to March provides the best weather for relaxing beach vacations. Southern Pacific beaches see fewer crowds in the green season.
Wildlife Spotting (Including Sea Turtles & Whales)
July to October is prime for humpback whale migrations (Pacific coast) and green sea turtles (Caribbean). Olive Ridley turtles nest in mass arrivals from December to February (Pacific). Monkeys and sloths are visible year-round, with improved sightings in the dry season due to sparser foliage.
Hiking, Volcano Visits & National Parks
Dry season ensures clear skies and safe trails, while the green season (especially the “little summer”) is best for birding and lush scenery. Arenal and Monteverde offer year-round adventure; expect more mud and waterfalls at their most spectacular in June–October.
Cultural Festivals & Sustainable Tourism Opportunities
Plan around key festivals for local immersion. Off-peak visits support community tourism and sustainable initiatives. Certified sustainable operators and local farm stays help reduce tourism impact and enhance authentic experiences.
Regional Hotspots: Best Time to Visit Each Area in Costa Rica
San José & Central Valley
Visit year-round for urban exploration and surrounding volcanoes. Dry season (Dec–Apr) features lower rain; mild temperatures (70–75°F) make for optimal walking and cultural tours.
Pacific Coast (North, Central & South)
North Pacific (Guanacaste) shines December–April with sunny, dry days. Central and South Pacific (Manuel Antonio, Osa Peninsula) are best December–March but transform into wildlife havens June–October.
Caribbean Coast & Puerto Viejo
Expect rain year-round, but September and October bring drier weather and vibrant Afro-Caribbean festivals. Visit for unique wildlife and cultural experiences off the main tourist track.
Nicoya Peninsula, Monteverde & Arenal
Nicoya’s beaches are at their best December–March; Monteverde’s cloud forests and Arenal’s volcano are accessible year-round, with drier, cooler trails January–April and most dramatic scenery June–October.
Special Considerations for Traveling to Costa Rica in 2026
Latest Travel Advisories & Health Updates (2026)
No major alerts as of early 2026. Standard vaccinations (hepatitis, typhoid) are recommended. Some increased flooding risk exists during September–October hurricanes; monitor local advisories and acquire travel insurance.
Sustainable & Responsible Tourism: New Trends and Local Tips
Eco-certification (like CST), low-impact activities, and community tourism are on the rise. Avoid single-use plastics, stick to marked trails, and visit lesser-known national parks to contribute positively.
How Climate Change is Impacting Travel Seasons
Recent climate data (1991–2020) reveal rising annual temperatures, longer green seasons, and intensified rainfall (especially September–October). Wildlife migrations may shift earlier by 1–2 weeks. Natural events such as hurricanes may impact accessibility and require updated planning.
Frequently Asked Questions About the Best Time to Travel to Costa Rica
