In Rohia, Tunisia, understanding the UV Index is essential for protecting your skin and overall health. With its semi-arid climate, the region experiences significant solar radiation, particularly during the peak hours of sunlight. Knowing the UV levels can help you take necessary precautions to prevent sunburn and reduce the long-term risks of skin damage. On typical days, UV Index values in Rohia can soar to 12—a level considered extreme—between noon and 1 PM. Thus, staying informed about these levels is not just a matter of comfort; it’s key to ensuring your skin’s safety in this sunny locale.
From 07:00 to 08:00, the UV Index shows a gentle increase from 2 to 3, signaling the start of a sunlit day. As the clock strikes 09:00, the index climbs to 6, marking a noticeable rise in UV exposure. By 10:00, it peaks at 8, but the real intensity hits at 11:00 with a striking 11—a clear indication that sun protection is vital.
