Understanding the UV Index is crucial for residents of Fengtai Chengguanzhen, China, where sun exposure can pose significant health risks. The region's climate zone Cfa means that summers can be hot and humid, leading to elevated UV levels, especially during midday hours. Awareness of UV levels not only helps in preventing painful sunburns, but also plays a vital role in long-term skin health. With peak UV readings reaching a startling 10 between noon and 1 PM, being informed about UV Index levels is essential for the community to engage in safe sun practices and protect their skin.
The UV Index rises sharply as the day unfolds, kicking off at a gentle 1 at 07:00. However, by 08:00, it climbs to 3, signaling increasing sun intensity. The real surge comes between 09:00 and 12:00, where it escalates to a peak of 10, urging sun safety precautions, especially during the sun's zenith from 11:00 to 13:00. As the afternoon progresses, the intensity wanes, dropping to 8 at 14:00 and gradually declining to 6 by 15:00. A further descent continues into the evening, with values plummeting to 1 by 19:00. This trend serves as a reminder to stay protected during the sun's most potent hours!
