Being aware of the UV Index is crucial in Shahrak-e Emam Hasan, where the region's BSh climate can lead to heightened sun exposure. Understanding UV levels is essential not only for preventing painful sunburns but also for safeguarding long-term skin health. With peak UV indexes reaching as high as 12 during midday, the risks of skin damage significantly increase. Knowing when to seek shade or apply sunscreen is vital for everyone enjoying the sunny days in this vibrant area.
As the sun rises, the UV Index begins its climb, starting at a gentle 1 at 7:00 AM. By 8:00, it ramps up to 3, but it’s between 9:00 and 11:00 that it truly peaks, reaching a striking 11 at 12:00 PM, the hour when sun protection becomes essential. The afternoon sun keeps its intensity, maintaining a strong 12 from 12:00 to 1:00 PM. However, as the day progresses, the index starts to dip, falling to 10 by 2:00 PM and gradually easing to 5 by 4:00 PM. Finally, the UV Index diminishes to a safe 1 by 6:00 PM, signaling the end of the solar intensity. It’s a clear reminder that midday hours demand vigilance against UV exposure! 🌞

The UV Index shows significant seasonal changes, with high-risk months for UV exposure primarily occurring from March to August. During this period, the UV Index escalates from a moderate level of 8 in March to an extreme high of 12 in May and June, providing a burn time as short as 10 minutes. In contrast, January and December demonstrate lower UV levels, categorized as moderate, allowing for longer safe exposure times of 30 minutes. Visitors and residents should take extra precautions from March to August by wearing protective clothing, applying sunscreen, and seeking shade to minimize the risk of UV-related harm during these months of high intensity. As the UV Index decreases in the fall and winter, exposure remains necessary, but the risk is markedly reduced.
