Because Costa Rica is located between 8 and 12 degrees north of the Equator, the climate is tropical year round. However, the country has many microclimates depending on elevation, rainfall, topography, and by the geography of each particular region.
Costa Rica’s seasons are defined by how much rain falls during a particular period and not to the four seasons in the Northern Hemisphere. The year can be split into two periods, the dry season known to the residents as summer, and the rainy season, known locally as winter. The “summer” or dry season goes from December to April, and “winter” or rainy season goes from May to November, which almost coincides with the Atlantic hurricane season and during this time, it rains constantly in some regions.
The 2011 census counted a population of 4,636,348 people The 2012 census classified 83.63% of the population as white or mestizo, Mulatos represent now 6.12% of the total population, 2.4% as Amerindian and less than 2% as black. Native and European mixed blood populations are far less than in other Latin American countries. Exceptions are Guanacaste, where almost half the population is visibly mestizo, a legacy of the more pervasive unions between Spanish colonists and Chorotega Amerindians through several generations, and Limón, where the vast majority of the Afro-Costa Rican community lives.
