Awareness of the UV Index is crucial for residents and visitors of San Nazzaro, Italy, where the pleasant Cfb climate can often lead to higher UV exposure levels. Understanding these UV levels is essential for preventing sunburn and protecting your skin health, especially during peak hours when indices soar to 9 between noon and 2 PM. With the sun's intensity rising swiftly in the morning and gradually decreasing in the afternoon, being informed about the UV Index allows you to enjoy the beautiful outdoors safely, minimizing your risks while soaking up the scenery of this charming locale.
The UV Index experience unfolds dramatically throughout the day, starting with a gentle maximum of 1 at 7:00 AM. As the sun climbs higher, the intensity increases, reaching 2 by 8:00 AM, and then surging to 3 at 9:00 AM. The peaks of the day occur around midday, with the index soaring to a robust 8 at 12:00 PM and hitting its highest point at 9 during both 1:00 PM and 2:00 PM. A gradual decline follows, where the UVI falls to 7 by 3:00 PM, then takes a further dip to 4 at 5:00 PM. As evening approaches, the UV levels taper off, settling back to a safe 2 by 6:00 PM and finally returning to a mild 1 by 7:00 PM. Stay protected during peak hours, particularly between 11:00 AM and 2:00 PM, when the sun's rays are most intense!
