When is the best time to go to Costa Rica? Best time for Weather, Wildlife, Surfing & Fishing.

Costa Rica is a country that doesn’t just have one “best” season—it has many. With tropical beaches, lush rainforests, active volcanoes, and vibrant wildlife, it’s a destination that can be enjoyed year-round. But depending on your priorities—whether that’s sunshine, fewer crowds, wildlife encounters, perfect waves, or peak fishing—you’ll want to plan accordingly.

In this guide, we’ll break down what is the best time to visit Costa Rica based on the weather, wildlife activity, surf conditions, and fishing seasons, so you can choose the best time of the year to visit Costa Rica for your dream trip.

Understanding Costa Rica’s Seasons

Before diving into the best months, it helps to understand Costa Rica’s climate patterns.

Costa Rica doesn’t have the traditional four seasons—it has two:

1. Dry Season (Verano) – December to April: This is the best time to visit Costa Rica weather-wise if you want warm, sunny days and almost no rain. The dry season is also the country’s peak tourist period.

1. Green (Rainy) Season (Invierno) – May to November: Known locally as the “green season,” this period sees more rainfall, especially in the afternoons. Mornings are often clear, and the rain keeps the forests lush and wildlife active. This season also offers lower prices and fewer crowds.

   
   

There are also shoulder months—May, June and November—that combine good weather with fewer tourists.

Dry Season: December to April – Sunshine & Peak Travel

If your ideal vacation is all about blue skies, warm beach days, and plenty of outdoor adventures, the dry season is likely the best time of the year to visit Costa Rica.

• Weather: Virtually no rain on the Pacific coast; sunny skies dominate.

• Best for: Beach vacations, hiking, snorkeling, ziplining, and volcano tours.

• Downsides: Higher prices and more tourists, especially around Christmas, New Year’s, and Easter (Semana Santa).

Tip: Book accommodations and tours well in advance if visiting during December or January—they sell out quickly.

Green Season: May to November – Lush Landscapes & Lower Prices

The rainy season has a bad reputation among some travelers. Still, it’s actually a fantastic time to visit—especially if you’re looking for lower costs, fewer crowds, and a richer natural experience.

• Weather: Expect sunny mornings with afternoon showers.

• Best for: Wildlife viewing, rafting, photography, and budget-friendly travel.

• Downsides: Heavy rains in September and October can cause road closures, particularly in the Osa Peninsula and Caribbean regions.

Shoulder Season Sweet Spots:

• May: End of dry season, so landscapes are still green, but prices are lower.

• November: Rain tapers off, skies clear, and the country prepares for high season.

Best Time to Visit Costa Rica for Weather

When travelers ask what the best time is to visit Costa Rica for weather, the short answer is December through April—especially for beach vacations on the Pacific coast.

Pacific Coast (Guanacaste, Nicoya Peninsula, Manuel Antonio)

• Dry Season: December–April is sunny and warm.

• Rainy Season: May–November brings lush landscapes but more humidity.

Caribbean Coast (Puerto Viejo, Tortuguero)

• The Caribbean follows a different pattern—its driest months are September and October, making this the opposite of the Pacific coast.

Central Highlands (Monteverde, Arenal)

• Cooler year-round with mist and clouds; the dry season is less rainy, but the green season brings stunning cloud forest scenery.

Best Time to visit Costa Rica for Wildlife

Costa Rica is one of the most biodiverse countries on Earth, and timing your trip around wildlife seasons can make your visit unforgettable.

Sea Turtles:

• Leatherback turtles: March–May (Pacific coast)

• Green & hawksbill turtles: July–October (Tortuguero, Caribbean coast)

• Olive ridley turtles: August–November, peaking in September (Ostional, Nicoya Peninsula – famous arribadas)

Whales & Dolphins:

• Humpback whales: Two migration seasons—December–April (Northern Hemisphere whales) and July–November (Southern Hemisphere whales). The overlap in September makes it the best month for sightings.

Birdwatching:

• Year-round, but December–April offers the best visibility. The green season brings nesting activity and migratory species.

If wildlife is your focus, the best time to visit Costa Rica for wildlife is often the rainy season (May–November) when animals are most active.

Best Time to Surf in Costa Rica

Costa Rica is a surfer’s paradise, with consistent waves year-round. But conditions vary by coast and season, so timing matters.

• Dry Season (Dec–Apr): Smaller, cleaner waves, especially great for beginners and intermediates on the Pacific coast.

• Rainy Season (May–Nov): Larger, more powerful swells, particularly on the Pacific’s southern and central coasts. September and October are peak months for experienced surfers.

Best time to fish in Costa Rica

Costa Rica is world-famous for sportfishing, and while you can fish year-round, certain months bring peak conditions for specific species.

Sailfish:

• Central Pacific (Marina Quepos, Marina Los Sueños): December–April peak season.

• Guanacaste: Strong secondary season May–August.

Marlin:

• Blue marlin: November–January.

• Striped marlin: December–March.

Inshore Fishing:

• Roosterfish and snapper can be caught year-round, but calmer seas in the dry season make for easier trips.
