Understanding the UV Index is crucial for residents and visitors in Arirahua, Peru, where the intense sun can significantly impact skin health. With the high-altitude climate characteristic of the BSk zone, UV levels can spike dramatically, particularly during midday, reaching a maximum of 10 between 11:00 AM and 12:00 PM. Awareness of UV levels is essential to prevent sunburn and long-term skin damage, as even short exposure at elevated indices can pose risks.
