Understanding the UV Index is crucial for the residents of Yinzhu, China, as it directly influences skin health and sunburn prevention. With maximum UV levels reaching 11 during midday, awareness of these values can help residents protect themselves from harmful ultraviolet radiation. Yinzhu's Cwa climate means hot, humid summers where UV exposure can escalate quickly, making it essential to stay informed about daily UV levels. By monitoring the UV Index, you can enjoy the sun safely while minimizing risks to your skin.
As the sun rises, the UV Index begins at a mild 2 at 07:00, gradually escalating to a moderate 4 by 08:00. By 09:00, awareness becomes crucial as the index climbs to 6. The sun reaches its peak intensity at 12:00 with a notable 11, indicating high risk for sun exposure. Fortunately, after 1 PM, the index starts to decline, reaching 8 at 14:00, then gradually dropping to 6 by 15:00. The late afternoon brings relief with values of 3 at 16:00 and cooling further to 1 by 18:00 and 19:00. It's essential to take protective measures during the peak hours, particularly between 10 AM and 2 PM, to safeguard your skin from harmful UV rays.
