Adobe’s Top Ten reasons for visiting Costa Rica in September

Costa Rica weather September:

Costa Rica has a tropical climate, which means rain is possible any time of the year. September marks one of the rainiest months in the central and Pacific regions. 

However, mornings are almost always clear and sunny. And it’s a great time to see the tropical flora in full bloom. September is also a great month to visit waterfalls and go whitewater rafting. The rivers are full, sparkling clean, and rapids are in full force.

 If you’re a thrill seeker, there’s no better time to visit Costa Rica’s rivers than September. 

Dry season on the Caribbean side of Costa Rica

Weather in Costa Rica in September on the Caribbean Coast is postcard-perfect. Although the Caribbean receives more rain on average than the rest of the country, September and October are the driest and best times to visit.

Costa Rica’s South Caribbean Coast is famous for its white sand beaches, excellent surf, and laidback Afro-Caribbean vibe. To the north is the fascinating Tortuguero National Park. Its watery canals and remote villages are only reachable by boat.

Fun things to do in Costa Rica in September:

Costa Rica has a fascinating culture and history. Travel in September and enjoy the unique opportunity to experience Costa Rican culture–with the Costa Ricans! 

September 15, for example, is Independence Day. It is one of the country’s most important festivals and celebrated nationwide. Parades, music, dancing, and delicious traditional cuisine are in full swing in every city and municipality. 

And if that isn’t enough… All the eco-tours that make Costa Rica famous are also available in September! In fact, because of the rains, it is the best time to see the rainforests thriving and full of wildlife. You can enjoy most of these activities in the rain, too!

What to do on a rainy afternoon? You can always visit a museum, stroll through a wildlife refuge, take a coffee tour, learn about the chocolate-making process, or sample Costa Rican cuisine. 

September and October are turtle nesting seasons

Four nesting sea turtles visit Costa Rica annually. Witnessing their arrival, sometimes in the thousands, is a fascinating experience.

In September and October, Atlantic Green and Hawksbill sea turtles arrive to the Caribbean Coast. Similarly, on the Pacific Coast, you’ll find Pacific Greens, Olive Ridleys, and Leatherbacks. 

Costa Rica September weather means discounts on lodging:

For years, travel agents and tourism websites claimed that it was best to avoid Costa Rica during the rainy season. And for this reason alone, most hotels and airlines offer “green season incentives” to attract visitors.

These discounted hotel rates, airline tickets, and vacation packages still exist. Travelers hoping to get the most from their travel budget should visit Costa Rica in September.

The average temperatures in September are comfortable:

The average national temperature in September across Costa Rica is 80 degrees Fahrenheit (about 27 degrees Celsius). You can’t get any better than that!

However, this is a mountainous country, and the higher you go, the cooler it gets. This rule applies no matter what month it is. So, if you plan to visit the Central Valley or Monteverde in September, you should pack clothing for both cold evenings and warm mornings. 

Visiting in September is a great time to see Arenal Volcano:


Because Costa Rica’s topography is so diverse, there are many areas with unique climates. These regions don’t follow the rainy season “rules” like everywhere else. 

A perfect example of a microclimate with good weather in September is La Fortuna. Also known as the home of Arenal Volcano. It’s said that September is one of the best months to visit the area. The trees and plants are in full bloom, wildlife is thriving, and the mornings and early afternoons are almost always sunny. 

Avoid crowds in the National Parks: 

During peak season–between December and March–Costa Rica’s most popular attractions and parks get crowded. September is a great month to visit the most national parks like Manuel Antonio.

Manuel Antonio National Park on the central Pacific Coast is extremely popular for its beautiful beaches and abundant wildlife. If you really want to experience the park in all its splendor, definitely visit it in September or another green season month.

The same goes for Arenal Volcano National Park. Its growing fame means crowded trails and attractions during the peak season. 

Whale watching season on the Pacific Coast: 

Thousands of migrating humpback whales journey across the Pacific Ocean to visit Costa Rica annually. They travel huge distances to breed and have their young in the warm waters near the coastline. 

The best time to see these magnificent creatures is in September and October when their numbers are greatest. Although you can usually spot whales anywhere along the coast, most tours concentrate on the central and southern regions. 

Don’t let the weather in September Costa Rica postpone your trip to Costa Rica. As you can see, it’s a wonderful time to visit!

We recommend you speak with an Adobe agent regarding the best vehicle type to rent in September. If you plan to visit numerous destinations, you may require a 4×4 or SUV.
