In Kalt, Germany, being aware of the UV Index is crucial for protecting your skin and overall health. Understanding UV levels helps you strategize your sun exposure, ensuring you prevent sunburn and long-term skin damage. With Kalt's Cfb climate, which boasts mild summers and relatively higher UV exposure during peak daylight hours—especially from 12 PM to 2 PM—it's important to stay informed. As the UV Index can reach levels as high as 8, knowing when to seek shade or wear protective gear can make all the difference in maintaining your skin’s health while enjoying the sunny days.

After this midday surge, the index begins a gradual decline, dropping to 7 at 3 PM, and falling further to 4 by 5 PM. As evening approaches, UV levels decrease significantly, resting at 1 by 7 PM. It’s a clear reminder to stay sun-safe during those peak hours!
