September falls squarely within Costa Rica’s “green season,” also known as the rainy season. Characteristically, this period experiences substantial rainfall, particularly in the afternoons and evenings, interspersed with periods of sunshine. This creates a lush, vibrant landscape and often lower prices for accommodations and tours.
The distinctive weather patterns of this month contribute significantly to the country’s biodiversity, nourishing its rainforests and cloud forests. While the term “rainy season” might deter some travelers, September offers a unique opportunity to witness the country’s natural beauty at its peak, with fewer crowds. Historically, this period has been a time of renewal and growth for Costa Rica’s flora and fauna.
