In Potec, Czech Republic, understanding the UV Index is crucial for safeguarding your skin and overall health. The UV Index measures the strength of ultraviolet radiation at a given time, and knowing these levels can help you prevent sunburn and long-term skin damage. With Potec’s Dfb climate, you can expect seasonal variations in UV exposure, but during peak hours—especially around midday—the UV levels can reach as high as 9, posing significant risks of overexposure. By staying informed about the UV Index, residents can take essential precautions to enjoy the sun safely and protect their skin health year-round.
As the sun rises, the UV Index begins its ascent, reaching a gentle 1 at 07:00. By 08:00, it doubles to 2, slowly warming up for the day ahead. Things heat up significantly by 09:00, hitting 4, and by 10:00, it climbs to a peak of 6. The zenith arrives at 12:00, where the index stands tall at 8, and by 13:00, it reaches a sizzling 9—the highest point of the day. As the afternoon wears on, the UV intensity begins to wane, dropping to 8 at 14:00 and then to 6 at 15:00. By 16:00, it cools further to 5, retreating to 3 by 17:00. The evening brings relief as the UV Index transitions back down to 2 at 18:00 and finally returns to a mild 1 by 19:00. This hourly journey highlights the importance of sun safety, especially during those midday hours when the UV rays are at their fiercest.
