In Suhong, China, being aware of the UV Index is crucial for protecting your skin and maintaining overall health. The UV Index measures the strength of ultraviolet radiation from the sun, which peaks during the day and can lead to sunburn and long-term skin damage if precautions aren’t taken. With Suhong's Cfa climate, residents and visitors often face varying UV exposure risks, especially during peak hours when the index can reach a maximum of 12 at noon. Understanding local UV levels helps you take proactive steps to enjoy the sun safely, ensuring both your skin’s well-being and your outdoor experience remain positive.
The UV Index begins its rise at 7:00 AM with a low of 2, gradually climbing to a moderate 3 by 8:00 AM. By 9:00 AM, it reaches 6, but it's at 10:00 AM when the sun truly bears down, peaking at a high of 9. The intensity continues to soar, hitting a maximum of 12 at 12:00 PM, making it the most UV-active hour of the day. From there, it subtly declines, dropping back to 11 at 1:00 PM, and 9 at 2:00 PM. The afternoon brings relief as the index falls to 6 by 3:00 PM and continues to decrease, settling at 4 by 4:00 PM. As the day winds down, the UV Index dips to 2 by 5:00 PM and further to a safe 1 by 6:00 PM and stays consistent through 7:00 PM. Stay sun-smart and avoid peak UV hours for your skin's safety!

High-risk months include May through August, where the UV Index consistently reaches extreme levels of 11 or 12 and the burn time is as brief as 10 minutes. As such, residents and visitors should take precautionary measures during these peak months, such as seeking shade, wearing protective clothing, and applying sunscreen regularly.
