Understanding the UV Index in Xiahan, China is crucial for safeguarding your skin and overall health. With its Dwb climate—which brings warm summers and cold winters—Xiahan faces significant UV exposure, especially during peak hours when the index can reach a staggering 11 around noon. Being aware of the UV levels helps you prevent sunburn and long-term skin damage. As the UV Index can fluctuate dramatically throughout the day, knowing when to seek shade or apply sunscreen can make all the difference in enjoying the sun safely.
The UV Index data paints a vivid picture of a day under the sun, starting with a gentle maximum of 1 at 7 AM. As the morning progresses, the index gradually climbs, reaching 3 by 8 AM and hitting 5 by 9 AM. However, the real intensity arrives around 10 AM, when the UV Index peaks at a striking 11—a clear signal to seek shade and protect your skin. It remains at this maximum level until 1 PM, heralding the highest potential for sunburn and skin damage. As the afternoon unfolds, the index begins to taper off, dropping to 9 at 2 PM, then further declining to 5 by 4 PM. By evening, the intensity wanes, returning to a mild 1 by 6 PM and staying low through the rest of the night. Enjoy the sunshine, but remember to stay safe during those peak hours!
