In Nahavand, Iran, understanding the UV Index is crucial for safeguarding your skin and promoting overall health. With the sun’s rays reaching their peak intensity, especially during the mid-afternoon hours—where levels soar as high as 13—it's essential to stay informed about UV exposure to prevent sunburn and long-term skin damage. Nahavand's Mediterranean climate (Csa) offers plenty of sunny days, but this also means a heightened risk of harmful UV radiation. By being aware of the daily UV Index, residents and visitors can take proactive measures to enjoy the beautiful sun while protecting their skin health.
Starting off the day at a modest UV Index of 1 at 7:00 AM, the sun’s intensity climbs steadily as the morning progresses. By 8:00 AM, it reaches 3, and by 9:00 AM, it hits 5, signaling the approach of midday. The peak of the UV Index occurs at 12:00 PM with a blistering 13, maintaining this level until 1:00 PM. A gradual decline follows, as the index drops to 12 by 2:00 PM, then recedes to 9 by 3:00 PM. The sun's rays continue to soften, fading to 6 at 4:00 PM, then to 3 at 5:00 PM. As evening approaches, the UV Index dwindles to 2 by 6:00 PM and finally returns to a safe 1 at 7:00 PM. Enjoy the sun, but remember to stay protected during those peak hours!
