Understanding the UV Index is crucial for residents and visitors in Geyuan, China, as it serves as a vital indicator of sun exposure levels throughout the day. With peak UV levels often exceeding 10 during the summer months, awareness of these readings is essential for preventing sunburn and promoting long-term skin health. Geyuan’s humid subtropical climate (Cfa) can intensify sun exposure risks, making it imperative to take protective measures during the highest UV index hours, particularly from 10 AM to 2 PM. By staying informed about the UV Index, you can enjoy the outdoors safely while protecting your skin from harmful effects.
As the day unfolds, the UV Index (UVI) reaches its peak around noon, soaring to a significant 12. Starting from a modest 2 at 7:00 AM, the intensity gradually escalates, hitting 4 by 8:00 AM and 6 by 9:00 AM. By 10:00 AM, the sun's rays intensify further, reflecting a 9 on the scale, ultimately culminating in a high of 11 at 11:00 AM. The sun remains fierce until 1:00 PM, maintaining an 11 before declining in the late afternoon. As the day wanes, the UVI decreases, dropping to 4 at 4:00 PM, then 2 at 5:00 PM, and winding down to a mere 0 by 7:00 PM. It's a clear reminder to relish the sun's warmth early on while taking precautions during the midday peak.
