In Petralia Soprana, Italy, understanding the UV Index is crucial for maintaining skin health and preventing sunburn. With its Mediterranean climate (Csa), the region experiences varying levels of UV exposure throughout the day, peaking around midday with an index reaching as high as 11. Awareness of these UV levels allows residents and visitors to take necessary precautions, ensuring they enjoy the sun safely while minimizing the risk of skin damage. Whether you’re exploring the picturesque landscapes or enjoying the vibrant local culture, keeping an eye on the UV Index can help you make informed choices for a healthier outdoor experience.
As the sun rises, the UV Index starts off gently at 1 by 7:00 AM, gradually climbing as the day progresses. By 10:00 AM, it reaches 6, signaling a notable increase in solar radiation. The intensity peaks at 12:00 PM with a striking 10 and continues to soar to a maximum of 11 at 1:00 PM, marking the hour of greatest exposure. As the afternoon unfolds, the index begins to taper off—dropping to 10 at 2:00 PM and 8 by 3:00 PM. By late afternoon, the UV Index gracefully descends to 4 at 5:00 PM, settling back to 2 by 6:00 PM and finally returning to a gentle 1 by 7:00 PM. This highlights the importance of sun protection during mid-day when UV rays are at their most intense.
