In Krasnaya Polyana, understanding the UV Index is essential for maintaining skin health and preventing sunburns. The area's Dfb climate brings about varied weather patterns, but UV levels can reach their peak intensity, particularly between 11:00 AM and 1:00 PM, when they score as high as 11 on the index. Being aware of these fluctuations helps residents and visitors alike to protect their skin and enjoy the beautiful outdoors safely.

As evening approaches, the UV levels decrease significantly, settling at 2 by 17:00, and then dwindling to a minimal 1 after 18:00. To sum up, it's crucial to take protective measures during the midday hours when the UV Index peaks, ensuring you're shielded from harmful rays.
