In Jiangzhou, China, staying informed about the UV Index is essential for protecting your skin and overall health. Understanding UV levels throughout the day helps you take proactive measures against sunburn and long-term skin damage. With a Cwa climate that brings warm summers and varying UV exposure risks, it's crucial to be aware of peak times—such as midday when the UV Index can soar to an extreme 14. By knowing the UV Index, you can enjoy the sun safely and maintain your skin's vitality while minimizing harmful effects.
As the sun rises, the UV Index begins its ascent, reaching a modest 1 by 7:00 AM. By 9:00 AM, it climbs to 4, indicating a gradual intensity. The real peak arrives at 12:00 PM, where it soars to a significant 13, and 1:00 PM brings the highest reading of 14, reflecting the sun's strongest rays. As the afternoon progresses, the index starts to decline, dropping to 12 by 2:00 PM, and further decreasing to 6 by 4:00 PM. Finally, as the day winds down, the UV levels return to a safe 1 by 6:00 PM, reminding us to always be mindful of sun exposure, especially during peak hours!

The UV Index exhibits significant seasonal variations, peaking during the summer months, particularly from June to August, when it reaches an extreme level of 14. These months, along with March through October, present a high-risk period for sun exposure, with burn times as short as 10 minutes. In contrast, January and February also display very high UV levels (indices of 8 and 10, respectively), necessitating caution. As winter approaches, UV levels decrease, with November at 8 and December reducing further to 7; burn times gradually increase, allowing for 15 to 25 minutes of safe exposure. Visitors and residents should prioritize sun protection, especially during the peak months, by wearing sunscreen, protective clothing, and seeking shade to minimize the risks associated with high UV radiation.
