In the charming coastal village of Vigrestad, Norway, understanding the UV Index is essential for protecting your skin and overall health. As the sun shines brightly throughout the summer months, awareness of UV levels can help prevent sunburn and long-term skin damage. With a Cfb climate characterized by mild summers, residents and visitors alike may underestimate the risks posed by UV radiation. Particularly during the peak hours between 11:00 AM and 3:00 PM, when the UV Index can soar to 7, vigilance is key in ensuring safe outdoor activities. Staying informed about the UV Index helps you enjoy the sun responsibly while safeguarding your skin’s health.
The UV Index today follows a distinct pattern, peaking at 7 around 1 PM and remaining elevated at this level until 3 PM. Early risers can enjoy moderate UV levels, starting at 1 at 7 AM and gradually increasing to 3 by 9 AM. As the sun climbs, it intensifies, hitting 5 by 11 AM and reaching its maximum of 6 at 12 PM. After the midday peak, the index settles back, decreasing to 5 at 4 PM and tapering off in the evening hours, with values dropping to 2 by 7 PM. To ensure sun safety, embrace shade and sunscreen during peak hours!

From January to February, the UV Index remains low (1-2), allowing for a burn time of 45 minutes, making skin protection less critical. March and April see a moderate rise (UV Index 3-4) with a reduced burn time of 30 minutes, suggesting that some protective measures are advisable during outdoor activities. The risk peaks in the high-risk months of May through August, where the UV Index reaches between 6 and 7, and burn time drops to just 25 minutes—strongly advising the use of sunscreen, protective clothing, and hats.
