Understanding the UV Index is essential for residents and visitors in Nis, Serbia, where the climate often brings sunny days and increased UV exposure. Awareness of UV levels is crucial not only for preventing sunburn but also for maintaining overall skin health and reducing the risk of long-term damage. With peak UV readings reaching a maximum of 10 around midday, it's important to be vigilant, especially during the summer months when Nis experiences significant sunlight. By monitoring the UV Index, you can enjoy outdoor activities while protecting your skin from harmful rays!
The UV Index throughout the day presents a fascinating curve of intensity. Starting at a gentle 1 at 7:00 AM, it gradually climbs to reach a peak of 10 between 12:00 PM and 1:00 PM, highlighting the midday sun's strong rays. As the clock ticks past 1:00 PM, the index begins to decrease, settling back to 4 by 4:00 PM, and tapering off to a low 1 by the evening hours of 6:00 PM through 7:00 PM. It's a reminder that while the sun can be vibrant and energizing, precautions are essential during those peak hours, especially from 11:00 AM to 1:00 PM when UV exposure can be most hazardous.

The risk then rises substantially starting in February, peaks during the summer months of May through August with very high ratings between 8 and 10—advising visitors and residents to minimize exposure to just 15 minutes during these months.
