In General A. Tejeda y su A. Graciano Sanchez, Mexico, awareness of the UV Index is crucial for safeguarding skin health and preventing sunburn. As one of the key indicators of solar radiation intensity, understanding UV levels can significantly impact how residents and visitors enjoy outdoor activities while minimizing risks. With a climate characterized by ample sunlight, the region experiences peak UV exposure from late morning to early afternoon, with the Index soaring to as high as 13 at noon.

At 07:00 and 08:00, the UV Index remains low, peaking at 1, making it a safe time for outdoor activities. However, as the day progresses, the sun’s intensity ramps up sharply. By 10:00, the index reaches 5, climbing to a striking 11 by noon. The day hits its peak at 13:00 and 14:00, with a UV Index of 13, warranting caution and sun protection. As the afternoon unfolds, you’ll find a gradual decline: readings drop to 11 at 15:00, then 8 at 16:00, further easing to 2 by 18:00, and finally settling back to 1 by 19:00.
