If you are planning to travel to Costa Rica or take a vacation during the months of June, July, August, or September, one of the most common questions travelers ask is: What kind of weather can I expect at Arenal Volcano National Park?
Arenal is one of Costa Rica’s most iconic destinations, famous for its dramatic volcano, lush rainforest, abundant wildlife, hot springs, and outdoor adventure activities. Understanding the weather during these months—often referred to as Costa Rica’s green season—will help you plan your trip more effectively and enjoy everything this spectacular region has to offer.
Where Is Arenal Volcano National Park Located?
Arenal Volcano National Park is located in northwestern Costa Rica, in the San Carlos Valley, near the town of La Fortuna. This region is often referred to as the “breadbasket of Costa Rica” due to its fertile soil and agricultural importance.
The geography of the area plays a major role in its weather patterns. Warm air from the Caribbean side meets cooler air from the mountains, creating frequent rainfall throughout the year. Even during the drier months, Arenal receives more rain than many other parts of Costa Rica.
Is June–September a Good Time to Visit Arenal?
Absolutely—if you understand what to expect.
These months fall within Costa Rica’s rainy or green season, but that does not mean constant rain all day long. In fact, many travelers are pleasantly surprised by how enjoyable the weather can be.
Typical Weather Pattern
- Sunny mornings
- Cloud buildup late morning
- Rain showers in the afternoon or evening
- Occasional full sunny days
- Cooler evenings due to cloud cover and rain
Rainfall helps keep the rainforest vibrant, rivers flowing, and waterfalls dramatic—making this one of the most photogenic times of the year.
