Understanding the UV Index in Tangjian, China is crucial for safeguarding your skin and overall health. With the city’s climate characterized by warm summers and moderate winters, residents and visitors must be vigilant about UV exposure, especially during peak hours when the UV Index can reach levels of 10—indicating a very high risk of harm from unprotected sun exposure. Knowing the daily UV levels is essential not only for preventing painful sunburns but also for reducing the long-term risks associated with skin cancer. In Tangjian, where the sun shines brightly, being informed about UV risks can make all the difference in enjoying a safer, more enjoyable outdoor experience.
As the sun rises, the UV Index starts off mild, peaking at 2 by 7:00 AM. By 8:00 AM, it climbs to 3, but the real intensity kicks in as the day progresses. At 9:00 AM, the index hits 6, and by 10:00 AM, it soars to a striking 8. The midday sun takes center stage at 11:00 AM and 12:00 PM, both registering a maximum of 10, indicating significant UV exposure. As the afternoon rolls in, the UV levels begin to decline—slipping to 9 at 1:00 PM, dropping to 7 by 2:00 PM, and further decreasing to 5 by 3:00 PM. A gentle descent continues until evening, as the index settles at 1 from 4:00 PM until 7:00 PM. This gradual ebbing reminds us to take proper precautions during peak hours, especially around midday!
