Cascading down to the Caribbean from the central mountains are Costa Rica's many great rivers, including the Reventazon. The Pacific side is marked by two broad peninsulas that hook out into the Pacific, the Nicoya and the Osa. It is a geographic curiosity that their shapes are almost identical, the Osa being a smaller rendition of the Nicoya. Costa Rica's climate is renowned as an atmospheric treat. Mild subtropical conditions prevail year-round, and discomforting temperature extremes and prolonged periods of gray are practically nonexistent.
Temperature varies mainly according to elevation, the higher the cooler.
The brunt of the rainy season lasts from May through November, while a brief dry spell pays a visit from February to April. Costa Rica's rain falls mainly on the Caribbean coast, giving the Pacific a much more arid climate. All rights reserved.
