In Xiguan, China, staying informed about the UV Index is crucial for protecting your skin and overall health. Understanding UV levels helps residents and visitors alike prevent sunburn and reduce long-term skin damage, which is particularly important in this Cwa climate region known for its warm summers. With peak UV levels reaching a high of 10 during midday, the risk of harmful exposure increases significantly. Being aware of these fluctuations allows you to plan outdoor activities responsibly and shield yourself from the sun’s harmful rays.
The UV Index throughout the day paints a vivid picture of sun intensity. Starting at a mild 1 at 7:00 AM, the index gradually climbs, reaching a more noticeable 3 by 8:00 AM. The real surge occurs between 9:00 AM and 12:00 PM, where it peaks at 10—a crucial time for sun protection. After that, it begins to gently decline, with 9 at 1:00 PM, 8 at 2:00 PM, and dropping further to 6 by 3:00 PM. As the sun starts its descent, the index sees a steady fall, ending at a comfortable 1 by 6:00 PM, making the later hours much safer for outdoor activities. Pay attention to the height of UV levels around midday for optimal sun safety!

Throughout the year, UV exposure changes significantly, with the highest levels occurring during the summer months. From March to August, the UV Index escalates from a moderate 7 in March to an extreme 11 in August, highlighting these as the high-risk months for sunburn and skin damage. Particularly April to August pose the greatest danger, with burn times decreasing to as little as 10 minutes in August due to the extreme UV levels. Residents and visitors are advised to take precautions during these months by wearing protective clothing, applying sunscreen regularly, and seeking shade to minimize sun exposure. In contrast, the UV Index is more moderate in January, February, November, and December, where burn times can extend to 30 minutes, suggesting that outdoor activities can be safer during these colder months.
