The UV Index throughout the day displays a dynamic progression in intensity. Starting off gently, the index hovers at a comfortable level of 1 from 07:00 to 09:00. However, as the sun climbs higher, we witness a noticeable surge: by 10:00, the level reaches 3, and by 11:00, it escalates to 5. Peak exposure occurs between 12:00 and 15:00, with the index soaring to 7 at noon and hitting a high of 10 by 14:00 and 15:00. Afterward, the UV levels begin to taper off, dropping to 9 by 16:00, and gradually retreating to 3 by 19:00. This data underscores the importance of sun protection during the sun’s zenith for outdoor enthusiasts.

The UV Index shows significant seasonal changes, with high-risk months occurring from April to September. During this period, the UV Index reaches extreme levels in June (11) and very high levels in April, May, July, August, and September (ranging from 9 to 10), resulting in burn times as short as 10 to 15 minutes. Conversely, the winter months of January and December experience low levels (UV Index 2) with longer burn times of 45 minutes. To protect yourself during peak UV months, it is essential for visitors and residents alike to limit sun exposure during the hours of highest intensity, wear protective clothing, and apply broad-spectrum sunscreen regularly to minimize the risk of sunburn and skin damage.
