Understanding the UV Index is crucial for residents of Hashtgerd, Iran, where the combination of a Mediterranean climate and intense sunlight increases the risk of harmful UV exposure. Being aware of UV levels helps in preventing sunburn and protecting skin health, which is especially important given the area’s peak UV Index readings that can soar to 13 during midday hours. With potential daily fluctuations in UV exposure, it's essential to monitor these levels to enjoy the sun safely while safeguarding your skin against long-term damage.
At 07:00 AM, the UV Index starts off low at 1, making it a safe time for early risers. As the sun ascends, the index rises steadily, reaching 3 by 08:00 AM.

The real surge occurs from 10:00 AM to 12:00 PM, where the UV Index peaks significantly at 9 and then hits its maximum of 13 at 12:00 PM—a crucial window for being mindful of sun exposure. The intensity begins to taper off after 13:00 PM, dropping to 11 at 14:00 PM, and further declining to 8 by 15:00 PM. As the day winds down, the UV index falls to 5 at 16:00 PM, then further dwindles to 3 by 17:00 PM, and returns to a safe 1 by 18:00 PM, finally settling at 1 again by 19:00 PM. For those spending time outdoors, it's vital to take precautions during the peak hours when the UV Index is at its highest!
