In Khorramdarreh, Iran, awareness of the UV Index is vital for maintaining skin health and preventing sunburn, especially given the Dsa climate that can lead to heightened UV exposure throughout the day. Understanding UV levels helps residents and visitors alike to make informed decisions about sun protection, particularly during peak hours when the index soars to a maximum of 13 around midday. With typical UV risks peaking between 10 AM and 2 PM, it’s crucial to stay vigilant and protect your skin. By staying informed about the UV Index, you can enjoy the beautiful outdoors while safeguarding your health.
As the sun rises, the UV Index begins its ascent, starting at a gentle 1 at 07:00. By 08:00, it ramps up to 3, but the real intensity strikes as the day unfolds.

The maximum UV intensity occurs at 12:00 and 13:00, soaring to 13—a time when protective measures are crucial. Following this midday peak, the index gradually dips, with levels at 11 by 14:00, and descending further to 9 at 15:00. As daylight wanes, the index falls rapidly, returning to 1 by 18:00 and lingering there until 19:00. Throughout this cycle, staying sun-smart is essential, especially during those blazing midday hours.
