In Sanpai, China, being aware of the UV Index is crucial for safeguarding your skin and overall health. Understanding UV levels is essential, as they can significantly impact your risk of sunburn and skin damage, especially during peak sun hours. In this Cfa climate zone, where temperatures can soar, the UV Index frequently peaks at dangerous levels, reaching a staggering 13 at noon. With consistently high exposure risks, staying informed about daily UV forecasts can help you take necessary precautions, ensuring you enjoy the sun safely while prioritizing your skin's well-being.
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.
