Understanding the UV Index is crucial for residents and visitors of Beifan, China, especially given its Cfa climate that brings a mix of warm summers and mild winters. Being aware of the UV levels—ranging from a moderate 3 in the early morning to a peak of 11 during midday—empowers you to take essential precautions against harmful sun exposure. Preventing sunburn and maintaining your skin health are vital, as overexposure to UV rays can lead to long-term effects. In Beifan, where peak UV levels emerge between 11:00 AM and 1:00 PM, it's important to stay informed and protect yourself to enjoy the vibrant outdoor lifestyle safely.

As the sun climbs higher, it gains strength, peaking at an intense 11 by 12:00 and 13:00, indicating a high risk of harm from unprotected sun exposure. The UV Index starts to descend after this peak, dropping to 9 at 14:00, and gradually easing into more manageable levels of 6 by 15:00 and 4 at 16:00. By the late afternoon and into the evening, the index cools off, returning to 2 at 17:00, and finally lingering around 1 for the rest of the evening. Planning your outdoor activities? The optimal window for sun exposure is from 10:00 to 14:00, but don't forget your sunscreen!
