Understanding the UV Index in Qasr-e Shirin, Iran, is crucial for protecting yourself against harmful ultraviolet radiation. Awareness of UV levels helps prevent sunburn and promotes long-term skin health, especially in a region where the sunny climate can lead to elevated UV exposure. During the day, particularly between 10:00 AM and 1:00 PM, residents should be vigilant as UV readings peak at levels that can cause damage in mere minutes. With this knowledge, individuals can take proactive measures to safeguard their skin and enjoy the beautiful, sunny days characteristic of Qasr-e Shirin's BSh climate.
The UV Index throughout the day showcases a clear pattern of rising and falling intensity. Starting at a mild 2 at 7:00 AM, the levels climb steadily, peaking at 11 by noon—the most intense period of sunlight. As the afternoon progresses, the index remains high, tapering off to 10 at 1:00 PM, before gradually descending. By 3:00 PM, it drops to 5, and the evening settles in with indices of 3 at 4:00 PM, and a gentle decline to 1 by 7:00 PM. This progression highlights the importance of sun protection during peak hours—particularly between 10 AM and 2 PM—when the UV exposure is at its highest.
