Understanding the UV Index in Longxing, China is crucial for protecting your skin and overall health under the sun. The UV Index serves as a valuable guide to help you gauge the potential for sunburn and long-term skin damage, especially during the peak hours of sunlight. Longxing experiences a humid subtropical climate, characterized by hot summers that can expose you to high UV levels, particularly around noon when the index reaches a maximum of 12. By staying informed about UV levels, you can take proactive measures to safeguard your skin and enjoy the sunny days safely. Whether it's seeking shade, applying sunscreen, or wearing protective clothing, being aware of the UV Index can make all the difference!
At dawn, the UV Index starts off gently, peaking at just 1 by 7:00 AM. As the sun climbs higher, its intensity increases rapidly, reaching 4 by 9:00 AM and striking 10 by 11:00 AM—a clear warning to seek shade or slather on sunscreen. The highest reading of 12 occurs at both noon and 1:00 PM, indicating peak solar intensity. Fortunately, as afternoon approaches, the index begins to wane, dropping to 8 by 3:00 PM and further declining to below 5 by 4:00 PM.
