Understanding the UV Index is essential for residents of Penza, Russian Federation, as it provides crucial information about sun exposure and its impact on skin health. With the potential for serious sunburn and long-term skin damage, being aware of UV levels can help you take proactive measures to protect yourself and your loved ones.

A noticeable jump occurs at 09:00, reaching 5, and the sun truly shines at 10:00 with a peak of 6. The intensity reaches its zenith at 11:00, hitting 7, and stays steady until 13:00. As the afternoon rolls on, the UV Index begins to gently decline, dropping to 6 at 14:00 before tapering off to 4 by 15:00. The sun’s rays soften to 3 by 16:00, and tranquility returns with values of 2, 1, and 1 from 17:00 to 19:00. Make sure to stay protected during those midday hours when the sun is at its strongest!
