Understanding the UV Index is crucial for residents and visitors of Kangan, Iran, where high levels of sun exposure are common due to its arid climate. The UV Index measures the intensity of ultraviolet radiation, helping guide you in preventing sunburn and promoting overall skin health. In Kangan, UV levels can soar significantly during peak hours, reaching a maximum of 11 around noon. With values frequently rising above 7 throughout the morning and early afternoon, being aware of these risks plays a vital role in safeguarding your skin against the sun’s harmful effects.
The UV Index throughout the day reveals a fascinating journey of intensity. Starting off mellow at 07:00 with a UV Index of 1, the day gradually warms up as the sun climbs higher, reaching a peak of 11 by 12:00 and 13:00. This is the critical period where protection from the sun becomes essential, as the UV rays are at their strongest. Following this zenith, the index begins to decline, dropping to 10 at 14:00, then gradually tapering off to 7 by 15:00. As the afternoon fades, it cools down again to 4 at 16:00 and settles back to a gentle 2 by 17:00. By 18:00, it’s a mere 1, marking the close of a day that highlighted the sun's powerful rays. Always remember, during those peak hours, a little extra sun protection goes a long way!

February and November also present higher risks, with indexes of 7 and 6, respectively.
