Understanding the UV Index is essential for residents and visitors of San Vittore, Switzerland, as it serves as a crucial indicator of the sun's intensity and potential harm to our skin. With UV levels peaking at 10 during the midday hours, awareness of these values can significantly aid in preventing sunburn and promoting skin health. Given San Vittore's Dfc climate, characterized by colder temperatures and varying sunlight exposure, it's vital to stay informed about UV risks, especially when the sun is at its strongest. Stay protected and enjoy the beauty of this charming location while keeping your skin safe!
As the sun rises, the UV Index begins to climb steadily throughout the morning, starting from a low of 1 at 07:00. By 09:00, it reaches 3, but the real surge occurs between 10:00 and 14:00, when it peaks at a remarkable 10. This indicates a high risk of harm from unprotected sun exposure. After 14:00, the intensity begins to wane, dipping to 8 at 15:00 and gradually decreasing to 3 by 18:00. As the day winds down, the UV Index falls back to a safe 1 by 19:00, reminding us of the importance of sun protection during those peak hours.
