Understanding the UV Index is crucial for residents of Huishan, China, where the unique climate brings varied sun exposure throughout the year. Being aware of UV levels helps in effectively preventing sunburn and safeguarding skin health, especially during the peak hours when UV Index readings soar. With typical levels reaching a maximum of 14 around midday, it's essential to take precautions against the heightened risk of skin damage. Whether you're enjoying outdoor activities or simply commuting, knowing how to navigate these UV challenges can significantly improve your overall well-being in this vibrant region.

The evening marks a return to safer levels, with the index falling back to 1 by 7:00 PM. This data underscores the importance of sun protection during the mid-day hours when the UVI is at its highest.
