In Los Silos, Spain, being aware of the UV Index is essential for safeguarding your skin and overall health. Understanding UV levels not only helps in preventing painful sunburns but also plays a crucial role in reducing the risk of long-term skin damage. With the region's Csb climate, residents and visitors alike should take note that UV exposure peaks during midday, reaching alarming levels of 12 around 2 PM. This means that while basking in the sun may be tempting, it's vital to arm yourself with knowledge to enjoy the beautiful weather safely.

The peak occurs at 1:00 PM, with a striking 11, shortly followed by the highest level of 12 at 2:00 PM—a time when sun protection is crucial! As afternoon turns to evening, the index gradually declines, falling to 6 by 5:00 PM and tapering off to 3 at 6:00 PM, before settling at a gentle 2 by 7:00 PM. This data highlights the importance of seeking shade and wearing sunscreen during the midday hours when UV exposure is at its peak.
