Understanding the UV Index is crucial for the residents of Hoernefors, Sweden. With average UV levels peaking at 6 during the midday hours, being aware of these fluctuations can help prevent sunburn and protect your skin health. The cool temperate climate (Dfc) may not seem like a significant risk for UV exposure, but when the sun is shining, the potential for harmful effects increases, especially during summer months. By monitoring the UV Index, you can enjoy the outdoors safely while ensuring your skin remains healthy and protected.
As the sun rises, the UV Index begins its ascent, starting at a mild 2 at 07:00. By 08:00, it ticks up to 3, indicating that the rays are becoming more noticeable. The morning reaches its peak at 12:00, where the index hits 6, a point where sun protection becomes essential. Throughout the afternoon, the index hovers around 6 before gradually descending as the day comes to a close. By 18:00, it drops back to 2, and by 19:00, it settles at a gentle 1, allowing for a more relaxed evening outdoors. Stay vigilant during the heights of the day to enjoy the sun safely!
