Understanding the UV Index is crucial for residents and visitors in Ostrovnoy, Russian Federation, where the climate presents unique exposure risks. With UV levels peaking at 5 around midday, being aware of these fluctuations is vital for preventing sunburn and promoting long-term skin health. The subarctic climate of Ostrovnoy, characterized by its distinct seasonal changes, means that while summer days may allow for outdoor enjoyment, they also pose a significant risk during hours of high UV radiation.

As the sun climbs higher, the index escalates to 4 by 10:00 AM and continues to hold steady until 1:00 PM. Following this peak, it begins to taper off, dropping back to 4 at 2:00 PM, and then declines further to 2 by 5:00 PM.
