The UV Index fluctuated throughout the day, peaking dramatically in the early afternoon. Starting from a modest 1 at 07:00, it climbed steadily, hitting a moderate 3 by 08:00. By 09:00, the index reached 6, signaling the sun's growing intensity. The real surge began at 10:00, where it skyrocketed to 10 and continued to rise, peaking at a striking 14 during 12:00. As the afternoon unfolded, the index began to dip, settling at 10 by 14:00 and further descending to 7 by 15:00.
