Understanding the UV Index is crucial for residents of Liutuan, China, a region characterized by its Dwb climate, which features distinct seasons and variations in sunlight intensity. With UV levels peaking at a concerning 10 during midday hours, awareness of these readings is vital for sunburn prevention and maintaining skin health. Elevated UV exposure can lead to immediate skin damage and long-term risks, making it essential for locals and visitors alike to stay informed. As you enjoy the outdoor beauty of Liutuan, being cautious about UV levels will help you stay safe and protect your skin from potential harm.
Throughout the day, the UV index displays a dynamic pattern, peaking dramatically in the late morning. Starting at a modest 3 at 07:00, the index climbs steadily, reaching a peak of 10 by 11:00 and remaining high until 12:00. Sun-seekers should take caution, as the intensity of UV radiation is at its highest during this time. After 13:00, there's a noticeable decline, with values dropping to 8, followed by 6 at 14:00, and then a gentle tapering off to 4 at 15:00. As the day progresses, the UV index dips further to levels of 3 at 16:00 and settles at a low of 1 from 17:00 onwards. It's crucial to protect your skin during those peak hours, especially between 10:00 and 12:00, when the sun is most potent.

Throughout the year, UV Index levels display significant seasonal variations that warrant attention from both residents and visitors. Low-risk months occur from January to February and November to December, where the UV Index ranges from 2 to 3, allowing for longer safe exposure (up to 45 minutes in January and November). The high-risk months are April to August, peaking in July with a UV Index of 10, where the recommended burn time is just 15 minutes due to very high levels of UV radiation. This period necessitates proactive sun safety measures, including wearing sunscreen, hats, and protective clothing, particularly during midday hours when the sun is most intense. As the UV Index decreases in September and October, individuals can gradually ease their precautions, but maintaining awareness remains essential throughout the year.
