The best time to visit Costa Rica is from mid-December through April, when the Pacific coast and many inland destinations experience the country’s driest weather. These months are ideal for beaches, national parks, hiking and outdoor adventures.
Costa Rica has two primary travel seasons: the dry season from mid-December through late April and the green season from May through mid-December. However, weather varies significantly between the Pacific coast, Caribbean coast, Central Valley and mountainous interior.
The right season depends on whether you want sunny beach weather, green rainforests, migrating whales or fewer crowds. Travelers can also compare the best things to do in Puntarenas with the rainforests and Afro-Caribbean culture Puerto Limón is known for.
Best Time To Visit Costa Rica by Season
Dry Season: Mid-December to April
Best for: Beaches, Hiking & National Parks
The dry season is the most popular time to visit Costa Rica, particularly along the Pacific coast. Sunny days and lower rainfall create favorable conditions for Guanacaste, the Nicoya Peninsula, Manuel Antonio and inland destinations like Arenal.
January through March are generally the driest months along the Pacific coast. Temperatures can become hot in Guanacaste, while higher-elevation destinations remain cooler.
Key Events & Activities:
- Pacific Beaches: Swim, surf or relax along the coasts of Guanacaste, Puntarenas and the Nicoya Peninsula.
- National Parks: Explore Manuel Antonio, Corcovado and other protected areas with more accessible trails.
- Wildlife Viewing: Look for monkeys, sloths, toucans and other animals as they gather around available water and food sources.
Christmas, New Year’s and Easter are especially busy, so accommodations and tours should be reserved early.
Early Green Season: May to August
Best for: Lush Landscapes, Waterfalls & Wildlife
The green season begins in May, bringing refreshing rain and renewed color to forests and valleys. Mornings are often sunny, with showers developing during the afternoon or evening.
May and June can provide a good balance of green scenery and manageable rainfall. By July and August, rain becomes more frequent in many Pacific regions, though conditions vary by location.
Key Events & Activities:
- Waterfall Adventures: See rivers and waterfalls at their most powerful as seasonal rainfall increases.
- Sea Turtle Nesting: Look for leatherback turtles along the Caribbean coast through June and green turtles arriving near Tortuguero beginning in July.
- Whale Watching: Search for humpback whales arriving along the South Pacific coast from July onward.
Late Green Season: September to Mid-December
Best for: Wildlife, Fewer Crowds & Caribbean Travel
September and October are among the rainiest months along much of Costa Rica’s Pacific coast. Heavy rain can affect roads, trails and outdoor tours, particularly in remote areas.
The Caribbean coast follows a different weather pattern, and may experience relatively drier conditions during September and October. This makes Puerto Limón, Cahuita and nearby Caribbean destinations appealing alternatives.
Key Events & Activities:
- Humpback Whales: Watch for whales along the South Pacific coast during one of Costa Rica’s major migration periods.
- Green Sea Turtles: Visit Tortuguero during the July through October nesting season with an authorized guide.
- Limón Carnival: Experience music, dancing, food and Afro-Caribbean traditions in Puerto Limón during October.
November begins the transition toward drier weather on the Pacific coast, while early December can provide improving conditions before peak-season crowds arrive.
Costa Rica Weather by Region
Costa Rica’s Pacific coast has the clearest dry and green seasons. December through March is generally dry, April is transitional and rain becomes more frequent from May through October.
The Caribbean coast receives rain throughout the year and does not follow the same pattern. September and October can be relatively dry, while February through April may also bring periods of favorable weather.
The Central Valley, including San José, has milder temperatures because of its elevation. Mountain and cloud forest destinations like Monteverde can feel cool and misty even when coastal areas are hot.
Best Time To Visit Costa Rica for Beaches
The best time to visit Costa Rica’s Pacific beaches is from December through April. These months bring sunny weather to destinations such as Tamarindo, Manuel Antonio, Jacó and the Nicoya Peninsula.
The best time for Caribbean beaches may be September or October, when the coast experiences relatively drier conditions. Cahuita, Puerto Viejo and beaches near Puerto Limón follow a different weather pattern from the Pacific.
May, June and November can offer a balance of beach time, greener landscapes and fewer visitors.
Best Time To Visit Costa Rica on a Cruise
The best time to visit Costa Rica on a cruise is generally from December through April. Pacific cruise visitors arriving in Puntarenas can enjoy drier conditions for wildlife tours, national parks and outdoor attractions.
Caribbean itineraries may visit Puerto Limón, a gateway to Cahuita National Park, Veragua Rainforest Park and the Tortuguero Canals. Because this coast receives rainfall throughout the year, cruise visitors should prepare for showers in any season.

Best Time To Visit Costa Rica for Wildlife
Costa Rica offers wildlife viewing throughout the year, but timing matters for particular species. Humpback whales visit the Pacific coast during two general periods, from approximately July through October and again from December through March.
Sea turtle seasons vary by species and coast. Leatherbacks nest along parts of the Caribbean coast from approximately March through June, while green turtles are most common around Tortuguero from July through October.
Monkeys, sloths, crocodiles and tropical birds can be seen year-round. Guided nature tours often provide the best chance of spotting wildlife safely.
Best Time To Visit Costa Rica for Rainforests & Waterfalls
The best time to experience Costa Rica’s greenest rainforests and fullest waterfalls is from May through November. Seasonal rain transforms the landscape and increases the flow of rivers and waterfalls.
May, June and November may provide the best balance between lush conditions and manageable rainfall. September and October can bring challenging conditions along the Pacific coast.
Travelers primarily interested in hiking may prefer the dry season, when trails are less muddy and river crossings are generally easier.
Best Time To Visit Costa Rica for Fewer Crowds
The best time to visit Costa Rica for fewer crowds is from May through November. May, June and November are especially attractive for travelers who want quieter attractions without the heaviest seasonal rain.
September and October are among the least crowded months on the Pacific coast, but they are also among the wettest. The Caribbean coast may offer better weather during this period.
Avoid Christmas, New Year’s and Easter if lower visitor numbers are a priority.
Best Time To Visit Costa Rica on a Budget
The best time to visit Costa Rica on a budget is during the green season from May through November. Lower demand can lead to reduced rates for accommodations, activities and travel packages.
September and October may offer some of the lowest prices, but rain can interrupt outdoor plans. May, June or November usually provide a better compromise between cost and weather.
Travelers should compare regional conditions before booking because the Pacific and Caribbean coasts experience different rainfall patterns.
When Is the Best Time To Visit Costa Rica?
The best time to visit Costa Rica is from mid-December through April for dry weather, accessible trails and sunny Pacific beaches. January through March offers the most dependable, dry-season conditions.
Choose May, June or November for green landscapes, fewer crowds and potential savings. Visit the South Pacific from July through October for humpback whales or plan a Caribbean trip around sea turtle nesting and relatively drier weather in September or October.
Costa Rica is a year-round destination, but choosing the right region is just as important as choosing the right month.
