Understanding the UV Index is crucial for residents of Sirsilla, India, especially given the region's Aw climate, which is characterized by hot summers and significant sun exposure. The UV Index measures the strength of ultraviolet radiation and helps individuals gauge the risk of sunburn and long-term skin damage. By staying informed about UV levels, particularly when they peak between 10 AM and 2 PM, locals can take necessary precautions to protect their skin health. With peak UV Index values reaching as high as 15 during midday, awareness is vital for enjoying the sun safely while minimizing the risk associated with high UV exposure.
As the sun rises, the UV Index begins its ascent, starting at a low 2 at 7:00 AM. By 8:00 AM, it doubles to 4, signaling the need for some sun protection. As the day progresses, the intensity of ultraviolet rays intensifies dramatically, peaking at a high of 15 at 12:00 PM. This period marks the height of UV exposure, making it crucial to stay shaded or protected. The index gradually declines after 1:00 PM, with readings of 13 and then 9 at 2:00 PM, before tapering off to 6 by 3:00 PM, and sinking to a mere 1 by 5:00 PM. Finally, the UV exposure diminishes to 0 after 7:00 PM, closing out the day as the sun sets. Remember, during those peak hours, protect yourself from harmful rays to ensure a safe and enjoyable day!
