Best Time to Visit Costa Rica 2026: Dry vs. Green Season

Costa Rica has one of the most straightforward seasonal patterns in Latin America. Two seasons. A clear price difference. A few regional exceptions that catch travelers off guard. The tricky part is that “dry season” doesn’t mean sunshine everywhere, and “rainy season” doesn’t mean miserable weather every day.

What Does Costa Rica’s Dry Season Actually Look Like?

The dry season runs from December through April across most of the country. The Pacific coast, particularly Guanacaste and the Nicoya Peninsula, is the star of this period. Days are reliably sunny, roads are accessible and beach conditions are at their best. The Guanacaste region in March and April is genuinely desert-dry. Think cracked earth, brown hillsides and intense heat.

The Costa Rica Tourism Board (ICT) describes Guanacaste’s climate zone as tropical dry forest, which understates how dramatically parched it gets by late dry season. If you want lush green landscapes, visiting between February and April in Guanacaste will disappoint. If you want guaranteed beach days and minimal rain risk, it delivers.

Crowds follow the dry season closely. December through early January is peak travel for international visitors. Christmas and New Year’s week is the single most expensive time to visit. Hotel rates spike 30 to 50 percent compared to shoulder months. Book well ahead. By late January and through February, the crowds thin slightly while conditions remain excellent.

For the Costa Rica road trip route, the dry season months offer the easiest driving conditions on unpaved roads, especially for routes accessing the Osa Peninsula or more remote beach towns.

Why the Green Season Is Better Than Its Reputation

May through November is green season. Formerly called “rainy season” in tourism materials, most operators now use the friendlier term for a reason: the weather is genuinely fine much of the time.

Afternoons bring rain, typically from around 2pm to 5pm. Mornings are often sunny and clear. Evenings cool off after the rain. The landscape is intensely green. Waterfalls run full. Rivers are high. Wildlife is more active. Toucans and scarlet macaws are easier to spot in the cloud forest when the vegetation is at its densest.

The price difference is real. High-quality lodges and eco-resorts that cost $250 per night in January often drop to $150 to $180 in June. Flights are cheaper. Crowds thin significantly. You’ll have Tortuguero canals to yourself. Even the most popular sites like Arenal Volcano or Manuel Antonio National Park feel manageable.

The best value months within green season are May, June and October. September and October see the heaviest rains, especially in the Central Valley and along the Caribbean coast. If you’re planning waterfall hikes or ATV excursions on unpaved terrain, mid-May through late June offers green season savings without the worst rain windows.

How Does the Caribbean Coast Differ?

The Caribbean coast operates on an almost opposite schedule, which surprises many travelers. The Caribbean’s driest months are September and October, and a second dry period in February through March. The rest of the year, including peak Pacific dry season months like January and March, the Caribbean coast often sees heavy rainfall.

This matters if Puerto Viejo, Cahuita or the canals around Tortuguero are on your itinerary. A trip planned in February for the Pacific sun could mean rain on the Caribbean days. Budget travelers who want to experience both coasts in one trip should either plan for May (Caribbean is transitioning, Pacific has already rained a bit) or accept that weather will vary significantly between the two coasts.

Tortuguero, on the northern Caribbean coast, is also home to sea turtle nesting. Green sea turtles nest primarily from July through October, with peak activity in August. Leatherback turtles nest February through June. If turtle nesting is a priority, that determines the coast and the month simultaneously.

When Is the Best Time for Surfing in Costa Rica?

Surfing follows its own calendar in Costa Rica. For Pacific coast surf, read our complete Costa Rica surfing guide for break-by-break conditions, but the short version: the Pacific north (Tamarindo, Witch’s Rock) peaks December through March with offshore conditions. The central Pacific (Jaco, Dominical, Santa Teresa) gets consistent swells nearly year-round with a green season bump June through October from south swells. The Caribbean coast (Puerto Viejo, Salsa Brava) is best December through March.

What About Wildlife and Jungle Activities?

Wildlife watching doesn’t shut down in green season. In many ways it improves. Here’s the rough calendar:

Sea turtles: Pacific leatherbacks March to May, Pacific Ridleys July to December (Ostional), Caribbean greens July to October
Quetzals: March and April during nesting season in the cloud forests (Monteverde, Cerro de la Muerte)
Humpback whales: August through October (southern hemisphere migration) and December through March (northern)
Corcovado and Osa Peninsula: Drier access October through April, but the wildlife doesn’t thin in the wet season

Frequently Asked Questions

When is the cheapest time to visit Costa Rica?

May, June and October offer the lowest overall prices for flights and hotels. These months fall within green season but see less extreme rain than September. The Christmas-to-New-Year period is the most expensive window.

What is the green season in Costa Rica?

Green season (also called rainy season) runs from May through November on the Pacific coast. Rain typically falls in the afternoons for a few hours. Mornings are usually sunny. Prices are 30 to 60 percent lower than dry season and the landscape is lush rather than parched.

Which part of Costa Rica is best for wildlife in October?

October is excellent for the Osa Peninsula and Corcovado National Park, where wildlife density is high year-round. The Caribbean coast around Tortuguero sees peak green turtle nesting through this period. Monteverde cloud forest is good for quetzals in spring but October remains active for overall biodiversity.

How far in advance should you book Costa Rica during peak season?

For December and January travel, book hotels and tours at least three to four months ahead. Eco-lodges in Corcovado and Tortuguero fill up especially fast because access is limited. During green season you can often book two to four weeks out and still get good options.
