Understanding the UV Index is crucial for residents and visitors of Zhonghechang, China, where sunny days are common due to a Cwa climate. Being aware of UV levels helps in preventing sunburn and maintaining overall skin health, especially when the index peaks at 12 around midday, indicating very high exposure risk. With a significant increase in UV radiation from 09:00 to 13:00, it’s essential to recognize these patterns and take necessary precautions to enjoy the sun safely while protecting your skin from potential damage.
The UV Index data for the day reveals notable variations throughout the hours. Beginning with a mild start at 07:00 with a UV Index of 1, the intensity gradually ramps up, peaking at 12:00 when it reaches its maximum of 13. This signifies a high risk of harm from unprotected sun exposure, particularly between 11:00 and 13:00, when the index soars to its zenith of 12. The afternoon sees a gentle decline, with values dropping to 9 by 15:00, and gradually tapering off as the sun sets, returning to a low of 1 by 19:00. It’s a clear reminder to plan sun protection strategies around midday when the sun is at its strongest!
