Costa Rica is one of the world’s most biodiverse countries, home to lush rainforests, pristine beaches, and a staggering variety of wildlife. From colorful birds to exotic creatures of Costa Rica, it’s no wonder that nature lovers flock to the country year-round. But like any tropical destination, the best time to visit largely depends on what you want to experience and which ecosystems you’re eager to explore.
In this guide, we’ll look at the best times of year to experience Costa Rica’s nature in all its glory, whether you’re hiking through rainforests, spotting wildlife, or getting up close to marine life with scuba diving in Costa Rica.
Costa Rica’s Climate: A Year-Round Destination
Costa Rica’s climate is tropical, which means it’s warm and humid for much of the year. The country is divided into two main seasons:
The Dry Season (December to April): This is the high season for tourism and the best time for beach activities and wildlife watching in the Pacific regions.
The Green Season (May to November): Known for occasional rain showers, this is the low season, but it’s a fantastic time for lush landscapes and fewer crowds.
Both seasons offer distinct advantages depending on the type of nature or wildlife you want to see. Let’s dive into the specifics of each season.
The Dry Season (December to April): Perfect for Wildlife Viewing and Beach Time

The dry season is Costa Rica’s high tourist season, which brings sunny days and clearer skies, perfect for outdoor activities. If you’re planning to explore the country’s nature reserves and wildlife, this is the ideal time.
Wildlife Highlights:
During the dry season, wildlife tends to gather around water sources, which makes animal spotting a bit easier. Some of the creatures of Costa Rica you may spot include: Spider monkeys, howler monkeys, and capuchins, which are active during the dry season and can often be spotted in the treetops. The dry season is an excellent time to see vibrant species like the resplendent quetzal and scarlet macaws.
National parks like Corcovado and Manuel Antonio are in their prime during this period, offering easy access and lots of wildlife activity. If you want to see Costa Rica’s biodiversity at its best, this is the time to visit.
Scuba Diving Costa Rica:
The dry season also offers the clearest waters for diving. The Pacific coast, especially around Guanacaste, has excellent conditions for scuba diving. The visibility can reach up to 100 feet, allowing divers to explore vibrant coral reefs and encounter marine life such as whale sharks, turtles, rays, and various species of tropical fish.
The Green Season (May to November): Lush Landscapes and Fewer Crowds
The green season might bring more rain, but it also offers stunningly lush landscapes and fewer tourists. For nature lovers looking for an off-the-beaten-path experience, this season is a hidden gem.
Wildlife Highlights:
During the green season, many species of wildlife are more active, particularly amphibians, reptiles, and insects. This season is great for Frog watching. The red-eyed tree frog and other amphibians are more visible during the rainier months, as they thrive in the wet conditions. Sloths, these slow-moving creatures are easy to spot in the rainy season, often hanging out in the wet forest canopies, and Turtles. Nesting season for sea turtles typically starts in June and lasts through October. If you’re interested in seeing turtles lay their eggs or hatchlings make their way to the sea, the green season is ideal.
Rainforest Adventures:
With more rainfall comes vibrant greenery, creating the perfect backdrop for rainforest hikes. Trails like those in Monteverde and Tortuguero offer unique opportunities to explore dense jungle, encounter wildlife, and enjoy the incredible biodiversity Costa Rica is known for.
Best Time for Scuba Diving in Costa Rica

While scuba diving in Costa Rica is possible year-round, the best time depends on the coast you’re visiting.
Pacific Coast: The dry season is best for scuba diving on the Pacific side of Costa Rica, especially in areas like Guanacaste and the Catalina Islands. The waters are clear and calm, offering a high chance of encountering marine life, including manta rays, whale sharks, and turtles.
Caribbean Coast: The green season brings more rainfall on the Caribbean side, which can affect visibility. However, this side of Costa Rica is known for excellent dive spots like Cahuita National Park and Puerto Viejo, where you can explore coral reefs and encounter colorful marine species.
When Is the Best Time for You to Visit?
The best time to visit Costa Rica depends on what kind of experience you’re seeking. Here’s a quick breakdown:
Dry Season (December to April): Ideal for wildlife watching, scuba diving, and beach activities with the clearest weather.
Green Season (May to November): Perfect for lush nature, off-the-beaten-path adventures, and unique wildlife like frogs, sloths, and turtles.
Regardless of the season, Costa Rica offers endless opportunities to connect with its natural beauty. Whether you’re exploring the rainforests, relaxing on the beach, or discovering marine life, Costa Rica’s nature is always worth a visit.
