Understanding the UV Index in Chah Ab, Afghanistan is essential for residents and visitors alike, as it serves as a crucial indicator of the sun's intensity and the potential risk for skin damage. Being aware of the UV levels is vital for preventing sunburn and maintaining long-term skin health, especially in a region characterized by a Mediterranean climate (Csa) with hot summers.

This hourly fluctuation underscores the importance of sun protection during those peak hours, especially when the UV Index soars.
