In Zhenzhushan, China, awareness of the UV Index is crucial for maintaining skin health and preventing sunburn, especially given the region's Dwb climate, which can bring intense sunlight. Understanding UV levels helps residents and visitors alike take necessary precautions during peak exposure times, such as from 10 AM to 12 PM when the index peaks at 10. By staying informed about these fluctuations, you can effectively protect yourself from harmful UV radiation and enjoy the outdoors safely!
The UV Index unfolds a dynamic pattern over the day, starting with a modest 3 at 07:00.

From 09:00, when it hits 7, to its zenith, the index serves as a vivid reminder to stay protected.

This UV profile underscores the importance of sun safety during peak hours, especially before 15:00 when the UV Index is significantly higher.
