Understanding the UV Index in Jiudu, China is crucial for protecting your skin and overall health. With the region's humid subtropical climate (Cfa) and significant sun exposure, knowing the UV levels can help prevent sunburn and long-term skin damage. During peak hours, particularly between 11 AM and 1 PM, UV Index readings can soar to a high level of 13, posing risks even on seemingly mild days. By staying informed about UV fluctuations throughout the day, residents and visitors can take necessary precautions to enjoy the sun safely while safeguarding their skin health.
The UV Index shows a dynamic progression throughout the day, starting from a mild 2 at 07:00 and climbing steadily to a peak of 13 by 12:00. As the sun reaches its zenith, the index reflects the intensity of ultraviolet rays, hitting 12 at 13:00 before gradually declining. By the afternoon, it slips down to 6 at 15:00, then diminishes further to 2 at 17:00 and finally to a mere 0 as twilight descends at 19:00. It's clear that the highest risk for sun exposure occurs midday, making it essential to protect your skin during those peak hours!
