In Quchan, Iran, awareness of the UV Index is crucial for safeguarding your skin against the potentially harmful effects of sun exposure. Understanding UV levels not only aids in preventing sunburn but also plays a vital role in maintaining long-term skin health. With a Mediterranean climate (Csa), the region experiences intense sunlight, particularly during peak hours when UV levels can reach a maximum of 12 around midday. Being informed about the UV Index empowers residents and visitors alike to take necessary precautions, ensuring that outdoor activities remain enjoyable and safe under the Iranian sun.
As the sun rises, the UV Index begins to climb steadily, starting at a gentle 2 at 07:00. By 08:00, it ramps up to 4, indicating a moderate risk of harm from unprotected sun exposure. The real intensity kicks in at 09:00, reaching a high of 7, and peaks at 11:00 and 12:00, where it hits a maximum of 12, signaling a very high risk. As the afternoon progresses, the index gradually declines: it slips to 10 at 14:00, then drops to 7 by 15:00. The evening brings relief, with readings falling to 4 at 16:00, and winding down to 2 by 17:00 and finally 1 by 19:00. It's a reminder that while the peak sun hours pose significant risk, the latter part of the day offers a reprieve from the intense UV exposure.
