In La Cretaz-Roisan, Italy, staying informed about the UV Index is essential for preserving your skin's health and preventing sunburn. With alpine climate conditions that heighten exposure to UV rays, understanding the UV levels throughout the day can make a significant difference in your outdoor experiences. From a maximum UV Index of 11 during midday, residents and visitors alike should exercise caution and protect themselves, especially between the hours of 10 AM and 4 PM when the risks are greatest. Embracing UV awareness not only safeguards your skin but contributes to a healthier lifestyle in this beautiful mountain locale.
The UV Index shows a dramatic rise throughout the morning, starting at a mild 1 at 07:00 and climbing steadily to 3 by 09:00. As the sun reaches its zenith, the index peaks at an intense 11 between 13:00 and 14:00, indicating a very high risk of harm from unprotected sun exposure. After this peak, the index gradually declines; by 16:00, it falls to 7, and eventually eases to 2 by 19:00. Remember to stay protected during peak hours, especially between 11:00 and 14:00, when UV exposure is at its highest!
