Understanding the UV Index is essential for the residents of Aojiabao, China, where the subtropical climate can lead to significant sun exposure risks. Knowing the UV levels throughout the day is crucial for preventing sunburn and maintaining skin health. Particularly during the peak hours—between 10 AM and 2 PM, when the UV Index reaches a high of 11—it's vital to take protective measures. With daily temperatures and sunlight intensity typically high, being aware of the UV index can help you enjoy the outdoors safely while minimizing the risk of harmful effects from the sun.
As the sun rises, the UV Index begins its ascent. At 07:00, it starts at a low 3, but by 08:00, it reaches 4, indicating a gradual increase in sun exposure. The intensity peaks dramatically at 11:00 with a striking 11, signaling the highest risk for unprotected skin. From there, the index begins a steady decline, dipping to 10 by noon and gradually tapering to 5 by 15:00. As afternoon gives way to evening, the UV levels drop sharply to 3 at 16:00 and settle at a mere 1 from 17:00 onward. This data illustrates the essential need for sun protection during peak hours, particularly between 10:00 and 14:00, when the sun is most formidable.
