Understanding the UV Index is crucial for residents and visitors in Obergriesbach, Germany, where the climate's mildness can sometimes obscure the risks of sun exposure. The UV Index provides essential information about the strength of ultraviolet radiation on any given day, helping to prevent sunburn and promote skin health. Throughout the day, UV levels in Obergriesbach can reach a maximum of 8 around noon, making it important to stay informed and take necessary precautions to safeguard your skin against potential harm. With the region’s typical Cfb climate, be aware that even on overcast days, UV rays can still penetrate the clouds, emphasizing the need for UV awareness in all seasons.
The UV Index throughout the day exhibits a pronounced peak between noon and 2 PM, reaching a high of 8 at 1 PM, warning us to take extra precautions against sun exposure. Starting at a mild level of 1 at 7 AM, the index gradually rises to 4 by 10 AM and escalates to its maximum during the critical hours of 11 AM and 12 PM, hitting 6 and 7 respectively. As we move past 2 PM, the index begins to decline, tapering off to 5 at 4 PM and eventually dropping back to a comfortable 1 by 7 PM. Staying aware of these fluctuations is essential for protecting our skin and enjoying the sunshine safely!
