The UV Index reveals an early morning reprieve, starting at a gentle 1 at 7:00 AM and remaining low through 9:00 AM. However, as the sun climbs, intensity increases sharply, peaking at a 7 around noon, signaling the most potent UV exposure of the day. The early afternoon maintains a respectable UV level of 6 at 1:00 PM before gradually tapering off. By mid-afternoon, it drops to 4, then swiftly declines to 1 by 4:00 PM, and finally settles at 0 by 6:00 PM, marking the day's end for UV concern. This hourly trend underscores the importance of sun safety during peak hours, especially between 10 AM and 2 PM.
