Costa Rica in September falls squarely within the “green season,” also known as the rainy season. This period is characterized by lush landscapes, vibrant flora, and generally lower prices for accommodations and tours. While rainfall is expected, it typically doesn’t persist throughout the entire day. Instead, downpours often occur in the afternoons or evenings, leaving mornings sunny and clear. This pattern creates unique opportunities for travelers to experience the country’s natural beauty with fewer crowds.
This time of year offers several advantages. The rain rejuvenates the rainforest, resulting in spectacular waterfalls and thriving wildlife. The lower tourist density allows for a more intimate experience of Costa Rican culture and nature. Historically, September has marked the transition between the peak rainy season and the drier months, offering a balance between vibrant greenery and comfortable weather conditions. This makes it an ideal time for those seeking adventure and natural beauty without the high-season prices.
