In West Alto Bonito Colonia, understanding the UV Index is crucial for safeguarding your skin and overall health. With sunny days typical of a BSh climate, the UV exposure can escalate rapidly, especially during midday when levels peak. Awareness of UV levels is essential for preventing sunburn and long-term skin damage.

By staying informed about the UV Index, residents can take proactive measures to enjoy the outdoors safely and protect their skin.
Throughout the day, the UV Index displays a dynamic rise and fall in intensity, starting with a gentle 1 at 07:00 and maintaining low levels of 1 at 08:00. As the sun climbs higher, the index sharply escalates, reaching 2 by 09:00 and surging to 5 at 10:00. The peak UV Index occurs during midday, hitting a striking 12 at both 13:00 and 14:00, signifying the need for effective sun protection. Following this zenith, the UV levels gracefully decline, tapering off to 10 by 15:00, then 8 at 16:00, and dwindling back down to 2 by 18:00. The day concludes under fading sunlight, with the UV Index returning to a safe 1 by 19:00. Always take care to guard against those midday rays when the sun is at its most powerful!
