Understanding the UV Index is crucial for residents of Mianeh, Iran, where sunlight can be intense, especially during the peak hours of the day. This knowledge helps in preventing sunburn and maintaining skin health across all ages. With Mianeh's Mediterranean climate, characterized by hot, dry summers, the UV levels can soar, peaking at an alarming 12 in the early afternoon. By staying informed about the UV Index, locals can take essential precautions to protect themselves from potential skin damage and enjoy the outdoors safely.
The UV Index throughout the day presents a fascinating shift in sun intensity. At 07:00, the index starts low at 1, indicating a safe environment for outdoor activities. As the morning progresses, it steadily climbs, reaching 4 by 09:00 and 7 by 10:00. The sunshine peaks around 12:00, hitting a robust 11, and even escalates to 12 by 13:00, marking the apex of midday sun exposure. However, the index begins to gracefully descend after this high, dropping to 8 by 15:00, and tapering off to 3 at 17:00. As the evening sets in, the index returns to the safety of 2 at 18:00 and further recedes to a gentle 1 by 19:00. This data underscores the importance of sun safety during peak hours, particularly between 11:00 and 14:00, when protective measures are most crucial.
