In Chelno-Vershiny, understanding the UV Index is essential for safeguarding your skin and overall health under the sun's rays. The UV Index provides a daily measure of harmful ultraviolet radiation, which can lead to sunburn and long-term skin damage if not carefully monitored. With a Dfb climate, Chelno-Vershiny experiences varied weather, but summer months can bring elevated UV levels, particularly around midday, when readings peak at 7. By staying informed about UV levels—from the moderate index of 5 in the morning to the higher 7 during peak hours—you can take proactive steps for sunburn prevention and maintain healthier skin throughout the year.
The UV Index throughout the day demonstrates a clear pattern of intensity, peaking at 7 during the late morning to early afternoon hours. At 10:00 AM, the index reaches its maximum of 7, remaining steady until 1:00 PM. This indicates a significant risk for skin damage, so sun protection is essential during these hours. As the afternoon progresses, the UV Index begins to decrease, dropping gradually to 5 by 2:00 PM, and then further down to 1 by 7:00 PM. Overall, it’s a day that starts off with moderate UV levels, surging at mid-day, and then tapering off into the evening, making outdoor activities cautious yet enjoyable.

As spring arrives, March and April see a rise to 5, with a moderate exposure risk and a decrease in burn time to 30 minutes. The summer months of May through July hit a peak UV Index of 7, categorized as high exposure with a burn time of only 25 minutes—this period is critical for sun safety, especially for visitors and residents. Even in August, with a UV Index of 6, the risk remains high. As we transition into fall, the UV Index drops to 5 in September and 3 in October, signaling moderate exposure risks once again with a return to 30 minutes of safe exposure. In the late fall and winter, November and December revert to low UV levels of 2 and 1, allowing for longer burn times of 45 minutes. It is crucial for individuals to take protective measures during high-risk months from May to August, such as using sunscreen, wearing protective clothing, and seeking shade.
