Understanding the UV Index is essential for residents of Linxia Chengguanzhen, China, where elevated sunlight exposure can pose significant health risks. The UV Index provides crucial information about the intensity of ultraviolet radiation, helping you take preventive measures against sunburn and long-term skin damage. Given Linxia Chengguanzhen's Dwc climate, which is characterized by dry winters and mild summers, awareness of daily UV levels is crucial—especially during peak hours when the index soars to a maximum of 13 around midday. By keeping an eye on the UV Index, you can protect your skin and enjoy the sun responsibly.
The UV Index throughout the day demonstrates a dramatic rise, peaking at 13 between 1 PM and 2 PM. Early morning starts off gently, with a maximum of just 1 at 7 AM, gradually climbing to 2 by 8 AM. As the sun climbs higher, the intensity increases rapidly, hitting 9 at 11 AM and soaring to its zenith of 12 at noon. After this peak, the index begins its descent, tapering to 10 by 3 PM, and further dwindling to 4 by 5 PM, ultimately calming to 1 as evening approaches. This hourly ebb and flow underscores the importance of sun safety measures, particularly during the midday hours when the UV exposure can be intense.
