Understanding the UV Index is crucial for residents of Peristeri, Greece, where sunny Mediterranean days can lead to increased exposure to harmful ultraviolet rays. As a thriving urban area, Peristeri experiences significant UV levels, particularly between late morning and early afternoon. With UV Index values peaking at 10 during the hottest hours, awareness of these levels is essential for effective sunburn prevention and long-term skin health.
