Understanding the UV Index is essential for residents and visitors in Riesi, Italy, where the sun's rays can be particularly intense. With the region's Mediterranean climate characterized by warm summers, the risk of sunburn and long-term skin damage increases significantly.

The intensity starts to wane in the afternoon, dropping to 8 at 15:00, and further retreating to a gentle 1 by evening. It's a classic case of the sun's power, reminding us to stay vigilant and shield ourselves during those peak hours!
