In Mahdishahr, Iran, being aware of the UV Index is crucial for safeguarding your health under the intense sun. Understanding UV levels not only helps in preventing sunburn but also plays a significant role in maintaining long-term skin health. With the region's Csa climate, characterized by hot summers and high UV exposure, it's essential to stay informed about daily UV fluctuations. Notably, UV levels peak around midday, making it vital for residents and visitors alike to take precautions. Whether you're spending time outdoors or enjoying leisure activities, knowing the UV Index can help you enjoy the sun safely while minimizing risks to your skin.
Throughout the day, the UV Index reveals a dynamic pattern of sun exposure. Starting at 07:00, the index begins modestly at 2, gradually climbing through the morning. By 10:00, it peaks dramatically at 9, reaching a striking 12 at 11:00. The intensity continues to surge, hitting a maximum of 13 at 12:00 and maintaining this high until 13:00. As the afternoon unfolds, the index declines steadily: dropping to 11 at 14:00, then to 8 by 15:00. The later hours see a significant decrease, falling to 5 at 16:00 and settling back down to 2 at 17:00. As the sun sets, the index diminishes to 1 by 18:00 and remains steady through the night hours. This data highlights the critical need for sun protection during peak hours, especially between 10:00 and 13:00.

As the seasons change, so does the UV Index, highlighting the importance of sun safety throughout the year. January and December typically see a moderate UV Index of 4, allowing for a burn time of 30 minutes before skin damage can occur. However, from February to April, the UV Index escalates rapidly, peaking at 13 in May and June, categorized as extreme, with a burn time of just 10 minutes. The high-risk months are clearly concentrated from March to September, particularly in May and June, where caution is essential to avoid overexposure. Visitors and residents should consider using sunscreen, wearing protective clothing, and seeking shade during peak sun hours, especially during these higher risk months. As the UV levels drop again in October and November, it is still wise to maintain sun protection practices.
