In Sinjil, Palestine, awareness of the UV Index is crucial for protecting your skin from the sun's harmful rays. Understanding UV levels helps you prevent sunburn and maintain long-term skin health, especially during the peak hours between 10 AM and 2 PM when levels can soar to as high as 11 on the scale. With a Csa climate, Sinjil experiences warm summers that can expose residents and visitors to significant UV risks.
