With typical summer days revealing peak UV levels reaching 7 between noon and early afternoon, it's essential for locals to stay informed and take necessary precautions. Brilon's Cfb climate means that while summer days can be warm, cloud cover and varying weather patterns can lead to fluctuating UV exposure.

The highest point peaks at 12:00, 13:00, and 14:00 with a striking 7, urging everyone to take precautions.
