The Best Things to Do in Costa Rica During the Green Season
Costa Rica in the green season is quiet, green and full of life. The rain keeps the jungle fresh, animals are easier to spot and waterfalls are at their most impressive.
Costa Rica has plenty to offer whether you’re seeking outdoor adventures, wildlife experiences or seaside relaxation. If you visit during the green season – which falls outside the country’s peak travel months – you’ll find several advantages. Depending on where you go, you can enjoy fewer visitors, incredible animals, world-class waves and more.
When is Costa Rica’s green season?
In Costa Rica there are two seasons: the green season (or rainy season), which lasts from May to November, and the dry season, which runs from December to April. The green season is especially pronounced on the Pacific Coast and in the central regions; on the Caribbean Coast the weather is rainy year round, with some small seasonal variations.
Generally speaking, the green season in Costa Rica means more rain, higher humidity, slightly cooler temperatures and beautifully verdant scenery. Rain showers tend to occur in the afternoon and don’t usually last too long, so outdoor exploring is certainly still possible. Because it’s the low season for tourism, popular destinations are likely to be quieter.
What are the best green season activities?
Mornings are often clear during Costa Rica’s green season, making it ideal for wildlife encounters, rainforest hikes and water-based adventure sports. Below are some of the best things to do in Costa Rica between May and November.
Lizzie highlights that while the dry season from December to April is ideal for sunshine, the green season offers a quieter, more vibrant experience. She especially recommends visiting between May and August to enjoy lush landscapes, fewer crowds and the chance to spot humpback whales along the South Pacific coast.
Explore national parks
Some of Costa Rica’s national parks are at their most spectacular during the rainy season, when the foliage blooms into a bright palette of green (there’s a reason why it’s called the green season). These lush landscapes make parks like Manuel Antonio and Corcovado especially rich in wildlife activity, offering better chances to spot species that thrive in wetter conditions.
Experience wildlife watching
Although the dry season is often considered the best time to visit Costa Rica for wildlife spotting, the green season can be just as magical – if you know where to go. One of the biggest draws is the sea turtle nesting season, which occurs during the green season on both coasts; exact timing varies depending on the location and species.
For example, in Tortuguero you can see baby green sea turtles hatch in September and October. On the Osa Peninsula, the green season is the best time of year to spot sloths, migrating birds and humpback whales. July to October is peak season for whale watching on the Pacific Coast, as southern humpbacks migrate north from Antarctica to breed.
Go surfing
During the green season in Costa Rica, Guanacaste and the Nicoya Peninsula see the strongest waves of the year, making it ideal for intermediate and experienced surfers. While rainfall is expected, this period brings consistent, powerful swells – especially between May and October. With fewer people in the water, there’s more space to surf comfortably and enjoy longer, uninterrupted rides.
We recommend spending your nights at Nantipa in Santa Teresa, Nicoya Peninsula. This beachfront hotel sits in one of the world’s five Blue Zones, renowned for its surf with waves suitable for all skill levels, depending on the season.
Hike off-the-beaten-path trails
During the green season, many of the country’s best hiking trails are found in the central cloud forests. A remote area replete with misty mountain scenery and a big array of animal species. Because it’s off-peak, the trails are also likely to be quiet and peaceful.
Near the legendary peak of Arenal lies the Rio Celeste region, where you can trek to hidden waterfalls and hot springs. For those looking to combine hiking with world-renowned white water rafting, the Pacuare Reserve is a top choice. Higher rainfall also means that rivers and waterfalls are at their most impressive.

During the green season in Costa Rica, you can expect warm temperatures, sunny mornings and frequent afternoon showers – typically between 2p.m and 5 p.m. Coastal areas range from 25–32°C (77–90°F), while the Central Valley is cooler. Rainfall is heavier on the Pacific coast and conditions vary by region.
Yes, outdoor activities are still very much possible during Costa Rica’s green season. While rainfall is more frequent, mornings are often dry and ideal for hiking, wildlife watching, rafting and exploring national parks. Always check local weather conditions and allow for flexibility in your plans in case of afternoon showers.
The main downside of visiting Costa Rica in the green season is increased rainfall. Although it doesn’t usually rain all day, afternoon showers might make you lose a few hours that could otherwise be spent exploring. Heavy rain can also cause flooding and make certain areas harder to access. Temperatures remain relatively warm, but humidity is higher and mosquitoes tend to be more common.
Yes, all of Costa Rica’s national parks are open during the green season. Some may have slightly reduced hours; Carara National Park, for example, opens one hour later from May to November, and the Sirena sector of Corcovado National Park is closed in October. For the most part, opening hours remain the same as during the dry seasons.
The key to packing for Costa Rica in the green season is to be prepared for changing weather – especially rain. Make sure to bring a rain jacket and clothing that dries quickly. Pack a mix of items for different temperatures and activities, including beachwear and swimsuits, appropriate footwear and warmer layers for cooler conditions in the highlands.
