In Daying, China, staying informed about the UV Index is crucial for maintaining skin health and preventing sunburn. With a Cfa climate characterized by humid summers, residents and visitors alike can experience significant UV exposure, particularly during peak hours when the index reaches its maximum of 11 around noon. Understanding the daily UV levels not only helps you gauge when to seek shade or apply sunscreen, but it also empowers you to protect your skin from potential long-term damage. From the relatively mild UV Index in the morning to the intense midday sun, awareness of these levels is key to enjoying the outdoors safely.

Throughout the year, the UV Index exhibits significant seasonal changes, peaking in the summer months. From January to March, the index gradually rises from a moderate level of 4 to a very high level of 8, indicating an increasing risk of sunburn. The high-risk months are notably April through August, where the UV Index is consistently very high to extreme, especially in June and July, reaching a peak of 11. During these months, the recommended burn time shrinks to as little as 10 minutes. It is crucial for both visitors and residents to take preventive measures, such as wearing sunscreen, protective clothing, and seeking shade during peak sunlight hours, particularly from April to August.
