Understanding the UV Index in Tiahuanaco, Bolivia is crucial for protecting your skin and overall health, especially in this high-altitude region where UV exposure can be intense. The UV levels fluctuate throughout the day, peaking at 10 during midday, indicating that sunburn can occur quickly without proper protection.
