In general, Costa Rica's climate is a tropical one, with the two well-defined stations: a rainy one and a dry one. Varieties of the tropical climates exist determined by the height, the position of central mountainous axis and the marine influence. They are the following ones.

• Dry Tropical: presents a well-defined dry station and it is mainly in the North Pacific (province of Guanacaste).
• Humid Tropical: shows regular temperatures and rain;
  it is particular of the South Pacific.
• Very Humid Tropical: offers abundant rain throughout the year and high temperatures; it's found in the Caribbean coast.
• Mountain Tropical: appears in the Central Region and some of the mountainous sectors that surround it. In the summit of the mountains we find a cold climate.

Costa Rica's relief was originated by the shock between the Cocos and the Caribbean plates that produced, about 150 million years ago, the sprouting of volcanic islands in the Inter oceanic channel that separated North America with South America. This channel occupies the territories of present the Costa Rica and part of Nicaragua.

Costa Rica's mountainous system has a Northeast-Southeastern direction and crosses the whole country. It receives the name of central or longitudinal mountainous axis. It is divided in 4 mountain ranges called: Mountain range of Guanacaste, Mountain range of Tilarán, Mountain range of Talamanca and the Central Volcanic Mountain range.
