Understanding the UV Index is essential for residents and visitors in Gangtou, China, where the climate can be characterized as humid subtropical (Cwa). With peak UV levels often reaching a maximum of 10 between 11:00 AM and 1:00 PM, awareness of UV exposure is critical for preventing sunburn and maintaining skin health. Sun-related skin damage can accumulate over time, leading to serious health concerns such as skin cancer. Therefore, knowing when to seek shade and apply sunscreen is vital, particularly during the warmer months when UV exposure risks are at their highest in this picturesque region. Stay informed and protect your skin while enjoying the outdoors!
During the day, the UV Index experiences a significant rise, starting off at a modest 2 by 07:00. As the sun climbs higher, it reaches a peak of 10 at both 11:00 and 12:00, indicating a high level of UV radiation. It's crucial to protect your skin during these hours. Following this peak, the index begins to taper off, dropping to 9 at 13:00, and gradually falling to 1 by 19:00 as dusk approaches. This pattern underscores the importance of sun safety in the late morning and early afternoon, when UV exposure is at its most intense. Stay vigilant and enjoy the sun responsibly!
