Understanding the UV Index is essential for residents and visitors in Sandnes, Norway, especially as our beautiful coastal city enjoys a temperate maritime climate (Cfb), which can lead to varying UV exposure. Awareness of UV levels is crucial in preventing sunburn and protecting skin health, particularly during the peak hours when the index rises to 6 or 7. With its long daylight hours in summer, Sandnes residents should be mindful of their sun safety to avoid the harmful effects of ultraviolet radiation. Staying informed helps you enjoy the sun safely while keeping your skin healthy for years to come!
