Understanding the UV Index in Shulan, China is essential for maintaining skin health and preventing sunburn, especially in a climate marked by significant seasonal variation. With UV levels peaking at 8 during the midday hours, being aware of these values helps residents take necessary precautions to protect themselves from harmful rays. In this Dwa climate zone, where summer sun exposure can be quite intense, knowing when UV levels are highest empowers residents to enjoy outdoor activities safely while minimizing the risk of skin damage.

The UV Index rises with the sun, peaking as the day unfolds. At 07:00, it begins at a mild 2, but by 08:00, it climbs to 4. The real heat arrives by 10:00, reaching a strong 7, and by 11:00 and 12:00, it hits its highest point of 8—a moment to seek shade or slather on that sunscreen! As the afternoon progresses, the index dwindles, dropping to 5 by 14:00, and continuing to decline through the late afternoon with 3 at 15:00, 2 at 16:00, and tapering off to a low of 1 by 17:00 and 18:00. Finally, as the day fades, the UV Index falls to 0 by 19:00, signaling a much safer time to enjoy the outdoors without worries. Remember to protect your skin when the sun is at its zenith!
