In Xiwu, China, understanding the UV Index is crucial for protecting your skin and overall health. With UV levels frequently reaching their peak intensity between 10 AM and 2 PM, knowing how to interpret these readings can help you prevent sunburn and long-term skin damage. The Cfa climate of Xiwu, characterized by warm summers, means that residents and visitors alike should be especially vigilant about sun exposure during these hours when the UV Index can soar to as high as 12—a level deemed extremely hazardous. Stay informed and keep your skin safe by checking the UV Index regularly!
At dawn, 7:00 AM, the UV Index is a mild 2, perfect for enjoying the early morning. As the day progresses, the intensity ramps up dramatically, peaking at 12:00 PM with a striking 12—the sun is at its fiercest, urging everyone to seek shade and stay protected. The UV Index begins to gradually decline after this peak, dipping to 10 at 1:00 PM and 8 by 2:00 PM, making the afternoon still quite bright but less intense. By the late afternoon, the UV levels drop further to 5 at 3:00 PM and continue to decrease, reaching a gentle 1 at 5:00 PM and maintaining that level into the evening hours until it finally settles at 0 after sunset at 7:00 PM. Overall, it's essential to be mindful of sun exposure during the height of the day!

During the year, the UV Index experiences significant seasonal variation, particularly peaking from March to September. The high-risk months are April to September, where the UV Index consistently reaches extreme levels of 10 or higher, with the shortest burn time of just 10 minutes in May through August. In contrast, the remaining months, such as January and November, show a high exposure category but allow longer burn times of up to 25 minutes. Therefore, it is crucial for both visitors and residents to take appropriate precautions during the high-risk months, such as applying sunscreen, wearing protective clothing, and seeking shade, while being more lenient during the cooler months. Remember, consistent sun safety is vital year-round.
