Understanding the UV Index is crucial for residents and visitors in Datong, China, especially given the region's Cfa climate, which brings its share of sunshine and exposure risks. Knowing the UV levels throughout the day can significantly aid in sunburn prevention and maintain skin health—an essential consideration in a place where midday readings can soar to 12. From the early morning to the late afternoon, it's vital to stay informed about UV intensity to protect yourself from harmful ultraviolet rays that can lead to immediate discomfort or long-term skin damage. By staying aware of the UV Index, you can enjoy the beautiful Datong skies while minimizing the risks associated with high sun exposure.
As the sun rises, the UV Index starts off mild at 1 at 07:00, making it safe to enjoy the morning outdoors. By 08:00, it increases to 3, signaling the need for light protection. However, the real intensity kicks in as the clock strikes 10:00, with the index peaking at a robust 12 by 12:00 and 13:00. During these hours, the sun’s rays are at their strongest, reaching a maximum of 11 at 11:00. As afternoon transitions into evening, the index begins to decline, dropping to 10 at 14:00 and gradually falling to 1 by 19:00. To make the most of your day, plan your outdoor activities in the early morning or late afternoon for a safer experience under the sun!
