In Yigou, China, staying informed about the UV Index is essential for protecting your skin and overall health. Understanding UV levels is crucial, as exposure to high ultraviolet radiation can lead to sunburn and long-term skin damage. With its Cwa climate, Yigou experiences significant UV intensity, especially during peak hours—hovering around 10 between noon and 1 PM. By monitoring the UV Index, residents can take proactive measures to enjoy the sunshine safely, ensuring their outdoor activities are both enjoyable and skin-smart.
The UV Index throughout the day paints a vivid picture of sun intensity. Starting at a mild 1 at 7:00 AM, the index gradually climbs, reaching a more noticeable 3 by 8:00 AM.

As the sun starts its descent, the index sees a steady fall, ending at a comfortable 1 by 6:00 PM, making the later hours much safer for outdoor activities. Pay attention to the height of UV levels around midday for optimal sun safety!
