With an index that spikes as high as 11 during midday hours, awareness of UV levels can significantly aid in sunburn prevention and long-term skin health.

Whether you're enjoying outdoor activities or simply soaking in the beautiful landscape, knowing the UV Index will help keep you safe while you bask in Nalbandyan's sunny charm.
