In Yao'an, China, awareness of the UV Index is crucial for maintaining skin health and preventing sunburn, especially given the region's humid subtropical climate (Cfa) that often amplifies UV exposure. Understanding the daily UV levels is essential for residents and visitors alike, as peak indices can soar to 13 during midday hours, posing significant risks. By staying informed about these fluctuations, you can take proactive measures to protect yourself from harmful effects of the sun and enjoy your time outdoors safely. With so much at stake, knowing the UV Index not only safeguards your skin but also enriches your outdoor experience in this beautiful locale.
As the day unfolds, the UV Index reaches its peak intensity during midday hours. Starting from a gentle 1 at 07:00, the index rises steadily to 3 by 08:00, then surges to a significant 9 by 10:00. The sun shines brightest at 12:00, where it hits a staggering 13, remaining there until 13:00. After this zenith, the UV levels begin to decline, dropping to 10 at 14:00 before gradually decreasing to 7 at 15:00. As the afternoon wanes, the UV Index settles back to 4 by 16:00, and continues its descent to 1 by 18:00 and 19:00. It's crucial to be mindful of sun exposure during those peak hours, particularly between 11:00 and 13:00, when the risk of harm from UV rays is at its highest. Stay safe and protect your skin!
