Understanding the UV Index is crucial for residents of Suixi, China, where the subtropical climate brings high levels of sunlight throughout the year. With maximum UV levels reaching 10 around midday, awareness of these values plays a pivotal role in preventing sunburn and maintaining optimum skin health. As UV radiation can peak significantly during the summer months, knowing how to protect yourself can help mitigate risks associated with excessive exposure. Whether you’re enjoying outdoor activities or simply spending time in the sun, staying informed about the UV Index is your first line of defense against skin damage in this vibrant region.
As the sun rises, the UV Index begins its ascent, peaking at an intense 10 at 12:00 PM. The day starts off gently, with a maximum of only 1 at 7:00 AM, but by 11:00 AM, it ramps up to 9, urging outdoor enthusiasts to take heed. From 9:00 AM through 1:00 PM, UV levels remain high, ranging from 5 to 10, emphasizing the importance of sun protection. As the afternoon unfolds, the index gradually declines, dropping to 5 by 3:00 PM and further down to 1 by the time the sun sets at 7:00 PM. So, whether you’re lounging by the pool or hiking through nature, it's essential to stay sun-savvy during those peak hours!
