Understanding the UV Index is crucial for the residents and visitors of Aiquile, Bolivia, as it serves as a vital indicator of the sun's intensity and its potential effects on skin health. With the region's Cwb climate, characterized by its moderate temperatures and sunny days, awareness of the UV levels can help prevent sunburn and long-term skin damage.

The UV Index demonstrates significant seasonal fluctuations, with extremely high levels persisting through winter and fall months. From January to April, the UV Index remains at a staggering 17 to 14, categorized as extreme, which means the potential for sunburn is very high, with a burn time of just 10 minutes.
