With the region's BSh climate, residents and visitors face significant UV exposure, particularly during midday hours when the index peaks at an intense 12. Understanding UV levels helps you protect your skin from harmful rays, ensuring a safe and enjoyable outdoor experience. As the sun rises, the UV index climbs rapidly, making it essential to stay informed and take precautions to minimize risk, especially between 10:00 AM and 2:00 PM when UV levels can be most dangerous.

By 09:00, it climbs to a moderate 3, but the real escalation hits by 10:00, reaching 6 as sunlight intensifies. The peak occurs at 12:00 with an impressive 11, and it edges even higher to 12 at 13:00, marking the day's highest UV exposure. This powerful sun begins to wane slightly, dropping to 11 at 14:00 and 9 by 15:00, before gently tapering off to a more manageable 7 at 16:00.
