Costa Rica has two seasons: the rainy season ("winter") lasts from May to mid-November; the dry season ("summer") lasts from mid-November to April. During the rainy season, days often start out sunny with rain falling in the afternoons and evenings. Be prepared for rain and cooler temperatures most afternoons during this season. This plentiful rain is what creates the lush green tropical flora and fauna that is so characteristic of Costa Rica. The dry season, because of its lack of rain, tends to be Costa Rica's high season for tourism, so prices all over the country are elevated during this season.

Temperatures in Costa Rica vary primarily with elevation, not with seasons. On the coasts, it's hot all year, while in the mountains it can be cool at night any time of year. The Central Valley is in a constant spring-like season, where weather varies and temperatures fluctuate. Humidity is a major factor on the Caribbean coast where it rains much more frequently than it does on the Pacific side.
