Understanding the UV Index is crucial for residents of Yanglu, China, especially given the area's Cwa climate which can present significant exposure to harmful ultraviolet radiation. With UV levels reaching their peak during midday, awareness of these fluctuations is essential for sunburn prevention and overall skin health. A high UV index indicates a greater risk of skin damage, making it vital for locals to take protective measures when the sun is most intense, typically between 10:00 AM and 2:00 PM. By staying informed about the UV Index, you can enjoy the outdoors while safeguarding your skin from potential harm.
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. By the time 7:00 PM rolls around, the UV danger has diminished significantly, settling back to a safe 1. Stay protected during those intense midday hours!
