Due to its location, Costa Rica has a spectacular tropical climate with average temperatures between 70 and 80 degrees Fahrenheit. This makes Costa Rica a place of diverse microclimates. Our country has two seasons: the dry season and the rainy season. The rainy season spans the months of May through November, and the dry season is from December to April. The seasons in the Caribbean of Costa Rica are the opposite. The dry season lasts from June until October, and the rainy season is from December to May. This helps make Costa Rica a biological corridor with 5% of the world's biodiversity in this region.
