Bolivia can be divided roughly into three climatic zones that differ greatly from each other. In the lowland regions (Trinidad und Beni), the climate is tropical. The temperatures range from warm to hot throughout the year, and average precipitation can be as high as 260 mm (10.24 in) in the rainy season.

So the best time to travel to Bolivia is probably the dry season, from April to September.

 

In the Altiplano, the Andean plateau, the climate is more moderate. In La Paz, for example, the annual temperature averages about 12° C (53.6° F). However, especially in the cooler and drier months from April to September, it can be quite cold when the sun is not shining. European travelers may be surprised that there is no heating in houses and inexpensive hotels, which is why they should be prepared for some cold nights.

The climate is more extreme in the Andes and can be considered subpolar, because here you will find snow and icy winds throughout the year.

These different zones make it difficult for travelers to dress appropriately. For this reason they should decide in advance where they are going to spend most of their time during their stay. Especially those who plan to visit the Salar de Uyuni will need warm clothes, including thermal underwear and a well-insulated sleeping bag because the only hotel at the Laguna Colorada has no heating. In addition, some of the windows are only covered with plastic sheeting, and the temperature can drop to as low as 20°C below zero at night.
