Understanding the UV Index in Genvry, France, is essential for protecting your skin and overall health. As UV levels fluctuate throughout the day, being aware of these changes helps prevent sunburn and long-term skin damage. Genvry's Cfb climate brings a mix of mild summers and cool winters, yet during peak summer months, UV exposure can pose significant risks, particularly between noon and 3 PM when levels soar to 8. By monitoring the UV Index, residents can safely enjoy outdoor activities while safeguarding their skin against harmful rays.
As the day unfolds, the UV Index intensifies significantly, peaking at 8 between 1:00 PM and 2:00 PM—a clear signal for sun safety. Starting from a modest 1 at 7:00 AM, the index steadily escalates, hitting 5 by 11:00 AM and reaching 7 just before noon. This upward trend continues until 2:00 PM, after which the UV levels gradually decline, dropping back to 4 by 5:00 PM and dwindling to 1 again by 7:00 PM. With this data in mind, it's vital to take protective measures during the midday hours when the sun is strongest. Stay sun-safe!

During these months, the exposure category escalates to very high, resulting in a burn time of just 15 minutes for unprotected skin.
