September falls squarely within Costa Rica’s “green season,” also known as the rainy season. Characteristically, this period experiences significant rainfall, particularly in the afternoons and evenings, interspersed with periods of sunshine. This pattern creates lush, vibrant landscapes and often lower prices for accommodations and tours.
Understanding the climatic conditions prevalent during this month is crucial for travelers. The abundance of rain contributes to the country’s renowned biodiversity, nourishing its rainforests and cloud forests. While the weather can be unpredictable, it offers a unique perspective on Costa Rica’s natural beauty. Historically, September has been a less crowded time to visit, allowing for a more immersive experience. The verdant scenery and reduced tourist traffic can be particularly appealing to nature enthusiasts and photographers.
