Understanding the UV Index is crucial for residents and visitors in Silvalen, Norway, where even a hint of sunlight can pose risks to skin health. Being aware of UV levels helps in preventing sunburn and long-term skin damage, making it essential for everyone, especially during the summer when indices can reach a peak of 6 around midday. With Silvalen’s climate classified as Cfc, the combination of mild summers and varying cloud cover can lead to unexpected increases in UV exposure.
