In Olloy-sur-Viroin, Belgium, staying informed about the UV Index is essential for protecting your skin and overall health. Understanding UV levels is crucial for preventing sunburn and reducing the long-term risks of skin damage, especially during peak hours when the index reaches as high as 8 between noon and 2 PM. The region’s temperate Cfb climate offers a mix of sunny and cloudy days, but even on overcast days, UV rays can still pose a threat. By monitoring the UV Index, residents and visitors can make informed choices about sun protection, ensuring enjoyable outdoor activities while safeguarding their skin.
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!
