Understanding the UV Index is essential for residents and visitors in Huangshan, China, where the picturesque scenery can often come with hidden health risks. As the sun's rays increase throughout the day, so too does the potential for sunburn and long-term skin damage—making awareness of UV levels crucial for protecting your skin. Huangshan's Cwb climate zone offers beautiful weather, but with maximum UV readings soaring to 14 in the afternoon, it's vital to plan outdoor activities wisely and take precautionary measures. By staying informed about the UV Index, you can enjoy the breathtaking views of Huangshan while ensuring your skin health remains a top priority.
The UV Index throughout the day showcases a striking pattern of intensity. Starting with a maximum of 1 at 7:00 AM, the sun rises steadily as the index climbs to 2 by 8:00 AM. By 9:00 AM, the UV intensity reaches 4, but it truly peaks from 11:00 AM to 2:00 PM with relentless values of 10 and surging to a remarkable 14 by 1:00 PM. As the afternoon progresses, the index begins to taper off, dropping to 11 at 3:00 PM, then sliding down to 8 at 4:00 PM. By evening, a gentle decline continues, ending the day with a 1 at 7:00 PM. This pattern serves as a reminder to embrace sun safety, particularly during those midday hours when protection is most crucial!

The UV Index shows significant seasonal variation, with the highest levels occurring from March through October, where values reach extreme levels of 12 to 16. February marks the transition into these intense months, with a very high index of 9, while November sees a return to very high levels as the year ends. The high-risk months for UV exposure are therefore March to October, where burn times are dramatically reduced to just 10 minutes or less. Visitors and residents should take precautions during this period by seeking shade, wearing protective clothing, and applying broad-spectrum sunscreen regularly. In contrast, January and December return to a high exposure category with longer burn times of 25 minutes, marking these as relatively safer months but still requiring UV protection.
