In Zlaté Hory, understanding the UV Index is essential for protecting your skin from harmful UV rays. As a picturesque town located in the temperate Dfb climate, residents and visitors alike must be aware of the varying UV levels throughout the day. With peak UV Index values reaching up to 8 in the early afternoon, the risk of sunburn and long-term skin damage increases significantly. By monitoring the UV Index, you can make informed decisions about sun protection, ensuring your time outdoors is both enjoyable and safe.
The UV Index throughout the day showcases a dynamic range of exposure, beginning at a low 1 at 7:00 AM and gradually climbing to a peak of 8 between 12:00 PM and 1:00 PM. This signifies a critical window for sun protection, particularly around 11:00 AM and 12:00 PM when the index reaches 7 and 8, respectively. As the afternoon unfolds, the index gradually declines, dipping back to 6 by 3:00 PM and then further to 4 at 4:00 PM. By the evening, the UV intensity has diminished to a gentle 1 at 7:00 PM. It's essential to stay aware of these fluctuations, ensuring that sun safety measures are taken during peak hours!
