Understanding the UV Index is crucial for residents and visitors in Wanna, Germany. With a Cfb climate, which brings moderate temperatures and seasonal variations, awareness of UV levels is essential for effective sunburn prevention and long-term skin health. The UV Index peaks between noon and early afternoon, reaching levels as high as 7, indicating that even brief sun exposure can pose risks. By staying informed about daily UV fluctuations, you can enjoy outdoor activities while safeguarding your skin against harmful ultraviolet radiation.
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. The afternoon sees an impressive UV index of 7 at 12:00 PM, maintaining this level until 2:00 PM—a prime time for outdoor activities, but remember to protect your skin! 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!
