Central America is not its own continent, but is considered part of North America geographically. Costa Rica, while being in Central America, is technically part of North America. The North American continent ends at either the Panama/Colombia border or the Panama Canal, depending on the convention you accept.
Costa Rica is located 10 degrees north of the Equator, and has no seasons as found in the temperate zones. The temperatures are the same all year long with small variations. In the Central Valley, where the capital city San Jose is located, the temperature average is 21 degrees centigrade (74 Fahrenheit).ue to the fact that Costa Rica is located between 8 and 12 degrees north of the Equator, we do not suffer the drastic changes of temperatures between one seasonal period and another, that characterize the temperate and cold zones. The major part of the Costa Rican territory enjoys thermal stability throughout the year.
