Understanding the UV Index is crucial for residents of Bilibino, Russian Federation, where even moderate sun exposure can significantly impact skin health. With the region's ET climate, characterized by cold temperatures and long hours of daylight during the summer months, familiarizing yourself with UV levels becomes essential for effective sunburn prevention. As the sun reaches its peak, particularly between 11:00 AM and 1:00 PM when the index can hit levels of 5 to 6, even brief outdoor activities can elevate your risk of harm. Stay informed and safeguard your skin from the sun’s powerful rays!
The UV Index throughout the day shows a steady climb, peaking during the midday hours. Starting at 2 at 07:00, it gradually rises to 6 by 13:00, indicating a heightened need for sun protection during these hours. As the afternoon wanes, the index dips back down, resting at 2 by 18:00 and tapering off to 1 by 19:00. Notably, the hours of 11:00 to 14:00, with values of 5 and 6, highlight the critical time to stay vigilant against overexposure to the sun. So, if you're planning to be outdoors, don your sunscreen and sunglasses, especially during those peak hours!
