In Huanta, Peru, understanding the UV Index is crucial for safeguarding your skin against harmful rays. With UV levels peaking as high as 13 around midday, residents and visitors alike must stay informed to prevent sunburn and protect long-term skin health. The region's Af climate adds to the risk, as its high altitude and clear skies can lead to greater UV exposure.

This is the critical window when sun exposure can cause harm, so seek shade or wear protective gear if you're outside! As the afternoon progresses, the index begins to dip: it drops to 11 at 1:00 PM, then to 8 by 2:00 PM, before further declining to 4 at 3:00 PM.
