Understanding the UV Index in Le Mesnil-sur-Oger is crucial for protecting your skin and overall health. As the sun's rays can cause sunburn and increase the risk of skin damage, being aware of UV levels helps you make informed decisions about sun exposure, particularly during the peak hours of 12 PM to 2 PM when values reach as high as 9—indicating a very high risk. Le Mesnil-sur-Oger, with its temperate climate, presents unique challenges as UV exposure can fluctuate dramatically throughout the year. By staying informed about the UV Index, residents and visitors can enjoy the outdoors safely, ensuring their time in the sun is enjoyable and damage-free.
The UV Index displays its daily performance, starting off with a low score of 1 at 07:00 and 08:00, making it a safe morning for outdoor activities. As the sun climbs higher, the index begins to rise sharply, reaching 4 by 10:00 and escalating to a striking 8 by noon. The peak intensity occurs from 13:00 to 14:00 with a maximum value of 9, indicating a critical time for sun exposure. Fortunately, the risk starts to decrease as the afternoon progresses, with values dropping to 6 at 16:00 and further to 3 by 18:00. Overall, while midday offers high UV exposure, the early morning and late afternoon present a more cautious sun environment, perfect for enjoying the day without excessive risk.
