Understanding the UV Index is crucial for residents of Tantou, China, where the climate often features high levels of solar radiation, especially during the peak hours of sunlight. Being aware of UV levels is essential for preventing sunburn and protecting skin health, as exposure can lead to long-term damage. In Tantou’s humid subtropical climate, UV levels reach their peak between 11 AM and 1 PM, soaring up to 12 on the scale, indicating a high risk of harm. With this knowledge, you can take proactive measures to enjoy the outdoors safely while safeguarding your skin against the sun’s harsh rays.
As the sun rises, the UV Index starts off at a mild 1 at 7:00 AM, gradually climbing to a moderate 2 by 8:00 AM. However, things heat up as the day progresses; by 10:00 AM, it peaks at an impressive 8. The highest solar intensity strikes from 11:00 AM to 1:00 PM, with a staggering maximum of 12 during the noon hour. As the afternoon rolls in, the UV Index begins to taper off, dropping to 8 by 3 PM, and further declining to a gentle 1 by 7:00 PM. It’s clear that the midday sun is the most potent—remember to protect your skin during those hours!
