In Xiachuan, China, awareness of the UV Index is crucial for safeguarding your skin health and preventing sunburn. Understanding UV levels helps residents and visitors alike make informed decisions about sun exposure, especially during the peak hours of 11 AM to 1 PM, when the UV Index reaches its highest point at 13—a level that indicates an extreme risk of harm from unprotected sun exposure. With Xiachuan's Cwa climate, characterized by warm summers and cold winters, the risk of UV-related damage can vary, but the sunny days often lead to heightened UV exposure risks. Staying informed on the UV Index empowers you to enjoy outdoor activities safely while protecting your skin.
From 07:00 to 19:00, the UV Index exhibits a pronounced peak during midday hours, soaring to 13 between 12:00 and 13:00. The intensity rises steadily from a mild 1 at 07:00 to a substantial 12 at 11:00, indicating peak sun exposure just before noon. As the afternoon progresses, the index gradually declines, dropping to 5 by 16:00 and further to a safe 1 as the sun sets. With a dramatic increase during the late morning and early afternoon, it's crucial to stay protected against UV rays, especially when the index hits 9 and above between 10:00 and 14:00.
