Understanding the UV Index in Shaft, Iran is crucial for protecting your skin and overall health. As the sun's intensity varies throughout the day, staying informed about UV levels helps in preventing sunburn and long-term skin damage. With a Cfa climate, Shaft experiences warm summers, making awareness of UV exposure especially important during peak hours when the index soars to levels of 11 around noon. By keeping an eye on the UV Index, you can enjoy the sun safely while minimizing health risks associated with high UV radiation.
The UV Index throughout the day exhibits a striking rise and fall, mirroring the sun's journey across the sky. Starting at a modest 1 at 7:00 AM, it quickly escalates to a notable 11 by 12:00 PM, making this the peak time for sun exposure. The intensity remains high for another hour before gradually declining, dropping to 7 at 3:00 PM and descending further to 1 by 7:00 PM. This pattern warns us to embrace the sun’s rays with caution, especially between 11:00 AM and 1:00 PM, where the UV levels soar. As the day winds down, the diminishing UV Index suggests a welcoming return to safer conditions. Remember, while the sun can be inviting, protecting your skin during peak hours is essential!
