Weather in Costa Rica: What to Expect Year-Round

Costa Rica is a country of breathtaking diversity—and that includes its weather. Thanks to its unique geography and tropical location, Costa Rica doesn’t experience the four traditional seasons. Instead, the country has two main seasons: dry season (summer) and green season (rainy/wet season). But even that’s just the beginning.

Whether you're heading to the sunny Pacific coast, the lush Caribbean shores, or the misty highlands, the weather can vary dramatically not only by region, but also by month. That’s why understanding the seasonal patterns—and how they shift across the country—is key to planning the perfect trip.

We want to make it easy for you to choose the ideal time and place for your Costa Rican adventure. Below, you’ll find a general overview of the weather, plus links to detailed monthly guides to help you pack, plan, and travel like a pro.

🌴 Costa Rica's Two Main Seasons

☀️ Dry Season (December to April)
Often referred to as "summer" by locals, this season brings plenty of sunshine, especially on the Pacific coast. It’s the most popular time to visit, with warm days, little rain, and perfect beach weather. Expect blue skies and ideal conditions for hiking, wildlife tours, and surfing.

🌧️ Green Season (May to November)
Also known as the "rainy season," this time of year brings lush greenery, vibrant rainforests, and afternoon showers—especially on the Pacific side. Mornings are usually sunny, with rain arriving later in the day. This season is beloved for its fewer crowds, lower prices, and dramatic natural beauty.

🗺️ Regional Weather Highlights

Costa Rica’s microclimates are heavily influenced by altitude and geography, so the weather can vary greatly across regions—even on the same day.

  • Pacific Coast: Dry and sunny from December to April; wetter and greener from May to November.

  • Caribbean Coast: Wetter overall, but September and October often bring unexpectedly dry and sunny weather.

  • Central Valley (San José, Heredia): Mild year-round with cooler nights; great for exploring cities and coffee plantations.

  • Mountain Regions (Monteverde, Arenal): Misty, cooler, and often wetter than coastal areas; beautiful cloud forests thrive here.
