Understanding the UV Index is crucial for residents and visitors of Garmen, Bulgaria, especially given the area's unique climate. The UV Index serves as a powerful tool in sunburn prevention and maintaining skin health, alerting you to the intensity of ultraviolet radiation at different times of the day. With Garmen's Cfb climate, sunny spells can result in high UV exposure risks, especially during peak hours when the index soars to 10 between 1 PM and 2 PM. Staying informed about these levels not only protects your skin but enhances your overall well-being under the beautiful Bulgarian sun.
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!
