The rainy summer, or so-called green season, is a spectacular time to see all the beautiful flora of Costa Rica. The bloom of the national flower orchid will not leave you emotionless. Moreover, this is the time when it becomes a little bit cooler and there are few showers once in a while. However, these don't usually last long, finishing in the evening. So this is a good time to travel cheaper. However, remember that some regions differ in seasonality, and for example, the Arena Volcano area is at this time experiencing the dry season.
