Understanding the UV Index is crucial for residents and visitors in Stalhille, Belgium, where the combination of a Cfb climate and varying seasonal sun exposure can significantly impact skin health. By knowing the UV levels throughout the day, you can effectively prevent sunburn and protect against long-term skin damage. With peak indices reaching as high as 8 around noon to mid-afternoon, awareness of these levels is essential for enjoying outdoor activities safely while minimizing UV exposure risks. Whether you're lounging in the sun or taking a stroll, ensuring you're informed about the UV Index can make all the difference for your skin's well-being.
As the day begins, the UV Index stays low, peaking at 1 during the early hours from 07:00 to 08:00. However, as the sun rises higher, the intensity of ultraviolet radiation climbs sharply.

The afternoon is marked by the highest levels between 13:00 and 15:00, where the UV Index soars to 8—a potent reminder of the sun's power. As the sun begins to dip, the UV levels gradually decline, settling at 5 by 17:00 and tapering off to 2 by 19:00. This hourly data highlights the importance of sun protection during peak hours, especially from 11:00 to 15:00, when UV exposure is at its highest.
