Climate

The climate of Bolivia changes drastically from one eco region to the other, from tropics in the eastern Llanos to polar climate in the western Andes. The summers are warm, humid in the east and dry in the west, with rains that often modify temperature, humidity, winds, atmospheric pressure and evaporation, giving place to different climates. When climatological phenomenon known as El Nino take place, it provokes great alteration in the weather. Winters are very cold in the West, and snows around the mountain range, while in the western regions, windy days are more usual. The autumn is dry in the non-tropical regions.
