Just a few hours’ travel from most of the United States and easily accessible from Europe and Canada thanks to nearly a dozen direct flights, Costa Rica is one of the world’s most popular vacation destinations.
Offering 800 miles of coastline on two oceans and 25.6% of its territory preserved in national parks and private reserves, Costa Rica is a nature-lover’s paradise.
So, when is the best time to visit Costa Rica? And where should you go? Well, that all depends on what you’re looking for.

Because of its tropical location near the equator, and being a country composed of microclimates, you can enjoy good weather pretty much all year long in Costa Rica. More or less, there are two seasons: dry and rainy. And keep in mind that Pacific and Caribbean climates are distinct.
In terms of wildlife, you can see sea turtles come ashore to lay their eggs almost year round, enjoy whale watching for almost seven months, and witness one of the largest bird migrations on the planet during certain times.
Based on a calendar year, here is a quick guide to when is the best time to travel in Costa Rica for weather, wildlife, nature and crowds.

- •It’s a great time to go to Pacific Coast beaches, like Hermosa, Tamarindo, Flamingo, Samara, Nosara, Santa Teresa, Jaco, Manuel Antonio and Dominical.
- •Strong trade winds cross the country creating ideal windsurfing and kite surfing conditions off the northern Guanacaste coast. There is also good surfing along the Pacific Coast.
- •The marshy wetlands of Palo Verde National Park in Guanacaste are filled with migrating and native birds, including endangered species like the Jabiru Stork.
- •Best time to hike in national parks like Corcovado, Rincon de la Vieja and Arenal Volcano, and visit the famous sky blue river, Rio Celeste.

May and June
- •The Pacific region transitions into rainy season (May to November) gradually with showers that become more frequent in June. The usual pattern is sunny mornings with afternoon or evening rains. The nice thing is the rain cools down temperatures and paints gorgeous green landscapes.
- •Occupancy rates and lodging prices drop at the end of April; and crowds lessen considerably after Easter until about the middle of June when northern summer vacationers start to arrive.
- •This is a good time to go whitewater rafting since the river levels rise from rain, creating more rapids, more adrenaline, and more fun!
