Understanding the UV Index is crucial for residents and visitors of San Lorenzo Isontino, Italy, where the combination of a Cfb climate and elevated UV exposure during peak hours can pose significant risks to skin health. With UV levels rising to a maximum of 9 between 1 PM and 2 PM, awareness of these fluctuating levels is vital for effective sunburn prevention. Taking precautions not only safeguards against immediate burns but also protects long-term skin health. Whether you're enjoying the outdoors or simply running errands, being informed about the daily UV Index is your best defense against harmful rays in this picturesque Italian town.

The peak arrives between 11:00 AM and 1:00 PM, where it soars to a striking 9 at 1:00 PM, which suggests strong sun protection is essential. Following this, the index slips down, recorded at 8 at 2:00 PM and 7 at 3:00 PM, offering a brief reprieve.
