In Xiliu, China, staying aware of the UV Index is crucial for protecting your skin against harmful ultraviolet radiation. Understanding UV levels not only helps prevent sunburn but also plays a vital role in maintaining long-term skin health. With Xiliu's Dwb climate, characterized by significant temperature variations, residents often face varying UV exposure, especially during peak hours when the index can soar to dangerous levels of 10 around midday. By monitoring the UV Index, you can make informed decisions about sun protection and enjoy the outdoors safely!
The UV Index throughout the day reveals a clear peak in sun intensity, making it essential to stay cautious during midday hours. Starting early, the UV Index begins at a mild 2 at 07:00, but quickly climbs to 3 by 08:00.

Following this, the intensity starts to dip, dropping to 9 at 14:00, then tapering down to 6 by 15:00, and continuing downwards to 4 at 16:00. By evening, the UV exposure decreases significantly, stabilizing at 2 at 17:00 and dwindling to a mere 1 by 18:00 and 19:00. Remember to apply sunscreen if you're out during those peak hours!
