In Cusy, France, being aware of the UV Index is crucial for safeguarding your skin against the sun’s harmful rays. Understanding UV levels is essential not just for preventing painful sunburns, but also for promoting long-term skin health. With Cusy experiencing a temperate climate (Cfb), the potential for increased UV exposure, particularly during peak hours like noon to 2 PM when the index reaches as high as 8, adds urgency to sun safety measures. Armed with knowledge about UV risks, residents and visitors can enjoy the sunshine while protecting their delicate skin.
As the sun rises over the horizon, the UV Index begins its ascent, starting at a modest 1 at 7:00 AM and creeping up to 3 by 9:00 AM. By 10:00 AM, the intensity increases to 4, but it's not until 12:00 PM that it peaks at 8, indicating a strong sun. This high level maintains a steady presence between 12:00 PM and 2:00 PM, suggesting it's the perfect time for sun protection. As the afternoon progresses, the UV Index gradually declines, dropping to 4 by 5:00 PM, and finally tapering off to 1 by 7:00 PM. Protecting your skin during the midday hours is vital when the sun's rays are at their most potent!
