Understanding the UV Index is crucial for residents of Shumerlya, where sunny days beckon but can also pose risks to skin health. As a city nestled in a Dfb climate zone, Shumerlya experiences varying UV levels throughout the day, peaking around noon with an index reaching 7, indicating a high risk of harm from unprotected sun exposure. Awareness of these UV levels helps in preventing sunburn and long-term skin damage, making it essential for everyone to check the UV Index ahead of outdoor activities.

As the sun rises, the UV Index begins its ascent, starting at a gentle 2 by 7:00 AM. By 8:00 AM, it's on the rise at 3, and at 9:00 AM, it reaches 4, nudging you to apply that sunscreen. The peak intensity hits at 12:00 PM with a robust 7, signaling the most potent sun exposure of the day. After this zenith, the index gradually retreats—down to 6 at 1:00 PM and 5 at 2:00 PM—before tapering off to a mild 1 by 6:00 PM. As the day cools off, the closing hours, from 4:00 PM to 7:00 PM, encourage outdoor enjoyment without the harsh rays, showcasing values of 4, 3, and finally resting at 1 in the evening.
