In Huashu, China, understanding the UV Index is crucial for protecting your skin against harmful ultraviolet rays. Being aware of UV levels helps you prevent sunburn and maintain overall skin health, especially during peak exposure hours when the index rises to 11 between 11 AM and 1 PM. This Dwb climate region experiences distinct seasonal shifts, leading to varying UV intensity throughout the year, particularly during sunny days. With typical UV exposure risks elevating as the sun climbs, it’s essential for residents and visitors alike to keep an eye on the UV Index to enjoy the outdoors safely.
As the sun rises, so does the UV Index, peaking during midday to remind us to take precautions. At 07:00, the index starts at a mild 3, gradually climbing to 5 by 08:00. The intensity reaches a striking 10 by 10:00, and hangs at an impressive 11 from 11:00 to 12:00—the highest point of the day. A slight decline follows, with readings of 9 at 13:00, and 7 at 14:00, before tapering off to 5 by 15:00. As the afternoon wanes, the index drops to 3 at 16:00, dwindling to a safe 1 from 17:00 onward, with the day wrapping up at a refreshing 0 by 19:00. Remember, during those peak hours, slather on the sunscreen!
