Understanding the UV Index in Krasnyy Bor is essential for safeguarding your skin health and preventing sunburn, especially given the region's diverse Dfb climate. With UV levels peaking at a notable 7 during midday hours, awareness of the sun's intensity can significantly reduce the risk of harmful exposure. Regular monitoring of UV levels not only helps to inform daily activities but also encourages the use of protective measures. As Krasnyy Bor residents and visitors enjoy the natural beauty, staying informed about UV risks is a vital step in enjoying outdoor activities safely.
The UV Index data illustrates a dynamic daily fluctuation in sun intensity.

After this peak, the index steadily declines, returning to a mild 1 by 7:00 PM. The highest readings at 11:00 AM and 12:00 PM emphasize the need for protective measures during the midday hours. Plan your outdoor activities wisely to enjoy the sunshine while staying protected.

The UV Index experiences notable seasonal fluctuations, peaking during the summer months. From January to February, the index remains low (1-2), allowing for a burn time of 45 minutes without substantial risk. As spring arrives in March and April, the index rises to a moderate level (3-4), decreasing the burn time to 30 minutes. The summer months of June and July are particularly high-risk, with UV levels reaching 7; it’s crucial for visitors and residents to limit sun exposure to just 25 minutes during this time. August sees a slight decrease to 6, but caution remains essential. As fall approaches, the index drops back to moderate (4 in September) and again to low levels (2-1) from October to December, allowing for longer safe exposure times of 45 minutes. Visitors and residents are strongly advised to protect themselves during high-risk months (June to August) with proper clothing, sunscreen, and shade, while maintaining awareness of changing UV levels throughout the year.
