Exploring Bolivia In December: Weather And Travel Tips

Bolivia in December is a mixed bag weather-wise, with moderate to very warm temperatures and varying levels of rainfall. It's the summer season, and the rainy season, so expect some downpours, but these are often short-lived and not heavy enough to disrupt travel plans. The temperature in lowland areas can soar to 30°C (86°F), while in cities like La Paz and Sucre, the average daytime temperature is a more pleasant 18°C to 22°C (64°F to 72°F). The nights can be chilly, though, especially in the highlands.

So, if you want to see the mirror effect on the salt flats and enjoy the festive atmosphere, December is the perfect time to visit Salar de Uyuni. However, if you prefer drier weather and clearer skies, the spring months of September, October, and November are ideal.
