Understanding the UV Index is essential for residents of Xiayang, China, especially given the region's Cfa climate, which often features clear skies and intense sunlight. With UV levels peaking at a staggering 13 during midday hours, being aware of these values is crucial for sunburn prevention and maintaining long-term skin health. As exposure risks rise throughout the day, particularly between 10 AM and 2 PM, staying informed allows you to take proactive measures against harmful UV radiation, ensuring a safer and more enjoyable experience outdoors.
The UV Index throughout the day reflects a dynamic shift in sun intensity, urging caution to those planning outdoor activities. Starting at a modest 2 by 07:00, the index surges as the sun climbs higher, reaching a peak of 13 at 12:00, marking the most critical hours for sun exposure. The intensity then begins to wane, dropping to 10 by 14:00 and further decreasing to a cooler 4 by the late afternoon. As the day winds down, the UV Index descends to 2 by 17:00, 1 at 18:00, and finally hits 0 by 19:00, signaling a safe retreat from the sun's rays. It's a clear reminder to prioritize sun safety during peak hours!
