In Kostomloty, Poland, staying aware of the UV Index is essential for safeguarding your skin and overall health. Understanding UV levels is crucial not only for preventing painful sunburns but also for minimizing long-term skin damage. With the region’s Dfb climate, which features cold winters and warm summers, UV exposure can vary greatly throughout the year. During peak hours, particularly between 11:00 AM and 3:00 PM, the UV Index can soar to levels 7 and 8, indicating a high risk for skin harm. By keeping an eye on the UV Index, residents can enjoy the sun safely while protecting their skin from its potentially harmful effects.
The UV Index throughout the day reveals a clear peak in sun intensity, providing a vivid illustration of solar exposure. Starting at 07:00, the index is a mild 1, indicating minimal risk. As the sun climbs higher, it rises to 3 by 09:00 and hits 6 at 11:00, urging early protectors to apply their sunscreen. The intensity reaches its zenith at 12:00, with a robust 7, and maintains 8 between 13:00 and 14:00, suggesting it's crucial to seek shade or cover during these hours. As the afternoon progresses, the figures gently decline, dipping to 4 at 17:00 and finally returning to a low 1 by 19:00. This hourly dance of the UV Index serves as a reminder to be sun-smart and make the most of outdoor activities while remaining vigilant during peak hours.
