Understanding the UV Index is crucial for residents of Longzhua, China, as it serves as an essential guide to protecting your skin from harmful ultraviolet radiation. With UV levels reaching a maximum of 9 during the peak hours of 10 AM to 1 PM, awareness can significantly reduce the risk of sunburn and long-term skin damage. Given Longzhua's Dwb climate, characterized by warm summers and cold winters, the sun can be particularly intense, especially during summer months. By staying informed about the daily UV index, you can take proactive steps to safeguard your skin health while enjoying the sunny days this vibrant region has to offer.
The UV Index climbs steadily throughout the morning, starting at a manageable 3 at 07:00 and surging to a peak of 9 between 10:00 and 12:00.

By the afternoon, the risks lessen significantly, with readings falling to 4 at 15:00, and a gentle decline continues into the evening, reaching 1 by 17:00 and finally settling at 0 after 19:00.
