Understanding the UV Index is crucial for residents of Gaozhou, China, where high levels of ultraviolet radiation can pose significant health risks. With a humid subtropical climate, the sun's intensity peaks during the summer months, making it essential to be mindful of UV levels to prevent sunburn and protect skin health. From 10 AM to 2 PM, the UV Index often soars to dangerous levels, reaching a maximum of 12, which highlights the importance of staying informed about daily fluctuations. By keeping a close eye on the UV Index, residents can enjoy the outdoors while safeguarding their skin from potential harm.
As the sun rises, the UV Index begins its climb, starting at a modest 2 by 7:00 AM. By 8:00 AM, it nudges up to 3, but the real surge happens around 9:00 AM, peaking at an intense 6. The midday sun blasts forth, pushing the UV Index to a staggering 12 by 12:00 PM—the highest point of the day. Stay alert as it hovers at 12 through 1:00 PM before gently descending to 9 at 2:00 PM. The afternoon brings a gradual decline, with the index dropping to 4 by 4:00 PM and dwindling to 1 by 6:00 PM, before finally settling at a trace level of 0 by 7:00 PM. It's clear: the peak sun hours demand caution and protection!
