Located 10° north of the Equator, Costa Rica doesn’t have summer and winter. Instead, it has the rainy season from May to November and the dry season from December to April. Though classified as tropical and subtropical climates, weather can vary greatly due to Costa Rica’s microclimates and diverse geography. The Central Valley — home to San Jose — ranges in elevation from 2,000 to 5,000 feet above sea level. In the highest elevations, the average temperature becomes cooler.
