The climate of Bolivia varies drastically from one eco-region to the other, from the tropics in the eastern ''[[Plain|llanos]]'' to a [[polar climate]] in the western Andes. The summers are warm, humid in the east and dry in the west, with rains that often modify temperatures, humidity, winds, [[atmospheric pressure]] and evaporation, yielding very different climates in different areas.

Winters are very cold in the west, and it snows in the mountain ranges, while in the western regions, windy days are more common. The autumn is dry in the non-tropical regions.
*''Llanos''. A [[Humidity|humid]] [[tropical climate]] with an average temperature of {{convert|25|°C|F}}. The wind coming from the [[Amazon rainforest]] causes significant rainfall. In May, there is low precipitation because of dry winds, and most days have clear skies. Even so, winds from the south, called ''surazos'', can bring cooler temperatures lasting several days.
*''[[Altiplano]]''. [[Desert climate|Desert]]-[[Polar climate|Polar]] climates, with strong and cold winds. The average temperature ranges from 15 to 20&nbsp;°C. At night, temperatures descend drastically to slightly above 0&nbsp;°C, while during the day, the weather is dry and [[Sunlight|solar radiation]] is high. [[Ground frost]]s occur every month, and snow is frequent.
*Valleys and ''Yungas''. [[Temperateness|Temperate]] climate. The humid northeastern winds are pushed to the mountains, making this region very humid and rainy. Temperatures are cooler at higher elevations. Snow occurs at altitudes of {{convert|2000|m|ft|sp=us}}.
*''[[Gran Chaco|Chaco]]''. [[Subtropics|Subtropical]] [[semi-arid climate]]. Rainy and humid in January and the rest of the year, with warm days and cold nights.
