Understanding the UV Index is crucial for residents of Kholmsk, Russian Federation, where the climate is characterized by cold, humid winters and warm summers classified as Dfc. Being aware of UV levels helps prevent sunburn and promotes overall skin health, making it essential for outdoor activities.

The seasonal UV changes indicate a gradual increase in UV Index as the year progresses, peaking during the summer months. January and February show low exposure levels (UV Index 2), allowing for extended burn times of 45 minutes. However, by March and April, the index rises to 4 and 5 respectively, marking a shift to moderate exposure with reduced burn times of 30 minutes. The high-risk months are May through August, where UV levels spike to a very high exposure category (UV Index 8-9), necessitating precautionary measures as burn times drop to just 15 minutes.
