Understanding the UV Index is crucial for residents of Rzewnie, Poland. With its Dfb climate, characterized by warm summers, awareness of UV levels can significantly impact sunburn prevention and long-term skin health. During peak hours—especially between 11:00 and 13:00, when the UV Index hits its maximum of 8—exposure risks are elevated, making it essential to protect your skin. By staying informed about the UV Index, you can enjoy the beautiful sunny days in Rzewnie while minimizing potential harm to your skin.
As the sun rises, the UV Index climbs steadily, starting at a moderate 2 at 07:00. By 08:00, it increases to a 3, signaling a gentle reminder to enjoy some early morning sunshine. The intensity peaks between 11:00 and 13:00, reaching a significant 8, making this the prime time for sun safety. After this midday high, the index gradually declines, slipping to 6 by 15:00 and dropping further to a 3 by 17:00. As evening approaches, it decreases to a mere 1 by 19:00, indicating a safe transition into the cooler hours. Remember, the highest UV exposure occurs when the sun is at its zenith, so don’t forget your sunscreen during those peak hours!
