Understanding the UV Index is crucial for residents of Hammah, Germany, as it serves as a vital indicator of sun strength and a guide to protecting your skin from harmful rays. The UV levels, which peak around midday with an index of 7, emphasize the importance of taking precautions to prevent sunburn and maintain skin health. Hammah experiences a temperate climate (Cfb), where sunny days can pose significant UV exposure risks, making it essential to stay informed and safe when enjoying the outdoors. By being aware of the UV Index, you can enjoy the beautiful weather while keeping your skin protected.
At dawn, the UV Index begins gently at 1 by 7:00 AM, ideal for a leisurely start. As the sun rises higher, the intensity increases, reaching 2 by 8:00 AM and climbing steadily to 4 by 10:00 AM. By 11:00 AM, it peaks at 5, signaling the sun’s growing strength.

As the day winds down, the index gradually declines, dropping to 6 at 3:00 PM and then tapering off to 4 by 5:00 PM, finally falling back to 2 by 6:00 PM and 1 again at 7:00 PM. It becomes clear: while midday brings the most sun strength, the shifting UV conditions throughout the day remind us to stay safe and enjoy the great outdoors responsibly!
