Understanding the UV Index is crucial for residents of Perushtitsa, Bulgaria, where sunny days can quickly turn into opportunities for overexposure. With peak UV levels reaching as high as 10 between noon and 2 PM, awareness of these levels is essential for preventing sunburn and protecting skin health. Given Perushtitsa's Cfa climate, characterized by warm summers, the potential for harmful UV exposure increases significantly during the day. Staying informed about the UV Index not only helps you enjoy the outdoors safely but also plays a vital role in long-term skin care.
The UV index begins its ascent at 07:00, starting at a gentle 1, then climbs gradually through the morning. By 10:00, it reaches a moderate 5, but from 11:00 onwards, the sun's intensity becomes pronounced, peaking at an impressive 10 between 13:00 and 14:00. After this zenith, the index dips to 8 at 15:00 and continues its decline, settling back to 2 by 18:00. As the day winds down into the evening, the UV index drops to a low 1 by 19:00, signaling a return to safer sun exposure levels. Enjoy the sunshine while staying protected during the high points!
