Understanding the UV Index is crucial for residents of Montaigu, France, as it serves as a vital tool for safeguarding skin health and preventing sunburn. With the sun's intensity peaking during midday hours, reaching levels as high as 8, awareness of UV levels can help you make informed choices about sun exposure. Montaigu, characterized by its Cfb climate, presents unique challenges, especially during warmer months when UV radiation can pose significant risks. By keeping an eye on the UV Index, you can enjoy the beauty of your surroundings while protecting your skin from harmful effects.
Today, the UV Index shows a dramatic rise as the sun reaches its peak. Starting from a low of 1 at 07:00 AM, it steadily climbs to 2 by 09:00 AM, before making a notable leap to 4 at 10:00 AM. The intensity hits 5 at 11:00 AM, and then surges to a scorching 7 by 12:00 PM. The peak of the day occurs at 1:00 PM, with the UV Index soaring to 8—a level that demands caution. This intensity remains high until 2:00 PM, only to begin its descent, dropping to 7 at 3:00 PM and subsequently to 5 at 4:00 PM. As the sun starts to set, the index gradually decreases to 2 by 6:00 PM and finally returns to 1 by 7:00 PM. It's a reminder to stay protected during those peak hours when the sun's rays are at their strongest!
