Understanding the UV Index is crucial for residents and visitors in Jishan, China, where the climate is characterized by warm summers and moderate exposure to sunlight. Awareness of UV levels not only aids in preventing painful sunburn but also plays a significant role in maintaining long-term skin health. Given the typically high UV exposure during peak hours—reaching a maximum index of 11 around noon—it's essential to stay informed and take protective measures. This proactive approach can significantly reduce the risks associated with UV radiation, helping you enjoy the beautiful weather while keeping your skin safe.
The UV Index data reveals a clear pattern in solar exposure throughout the day. Morning rays begin gently, with a maximum of 2 at 07:00, steadily rising to 4 by 08:00. As the sun climbs higher, the index peaks at an impressive 11 at 12:00, indicating a moment of intense UV radiation. Temperatures remain elevated with a 10 at 11:00 and 13:00, before gradually declining to 8 by 14:00. The afternoon light softens, dropping to 6 by 15:00, then continues to retreat as the sun sets—falling to 3 at 16:00, 2 at 17:00, and reaching 1 by 18:00 and 19:00. This data underscores the importance of protecting your skin during the peak hours, especially between 10:00 and 14:00, when the UV Index is at its highest.
