In Fengshan, Taiwan, staying informed about the UV Index is crucial for protecting your skin and overall health. Understanding UV levels helps prevent sunburn and reduces the risk of long-term skin damage, especially during the peak UV times. Fengshan's humid subtropical climate brings forth intense sun exposure, particularly between 10 AM and 2 PM, when UV Index levels can reach as high as 13. By keeping an eye on the UV Index, you can enjoy the sun safely while safeguarding your skin against harmful UV radiation.
The UV Index throughout the day showcases a striking pattern of intensity, peaking sharply around 11:00 AM and 12:00 PM with a robust 13, signaling a high risk for sun exposure during these hours. Early morning starts gently at 2 at 7:00 AM, then steadily climbs, passing through moderate levels at 8:00 AM and 9:00 AM, before reaching a critical point with a 10 at 10:00 AM. Post-noon, the index gradually declines, dropping to 6 by 3:00 PM and further to a much safer 1 by the evening at 5:00 PM and 6:00 PM, where it ultimately settles at 0 by nightfall. To enjoy the sun while protecting your skin, plan outdoor activities early or enjoy them after the peak hours!
