Understanding the UV Index in Qushan, China is crucial for maintaining skin health and preventing sunburn, especially given the region's humid subtropical climate (Cfa) that often brings sunny days. With peak UV levels reaching an alarming 12 around noon, awareness of UV exposure risks can help residents and visitors protect themselves against harmful effects of the sun. By monitoring the daily UV Index, individuals can make informed decisions about sun protection, ensuring their outdoor activities are safe and enjoyable under Qushan's vibrant skies.
As the sun rises, the UV Index begins its ascent, reaching a moderate level of 2 by 7:00 AM. By 8:00 AM, it climbs to 4, signaling a gradual start to sun exposure. The peak occurs at 12:00 PM, when the index hits a maximum of 12, marking the day's highest risk for skin damage. From this point, it begins to taper off, descending to 10 at 1:00 PM and gradually lowering to 1 by 5:00 PM, signifying a safe end to daylight activities. As evening approaches, the UV Index drops to 0, wrapping up the day's sun journey. Be sure to take precautions during those midday hours when the sun's intensity is at its strongest!

January and December see moderate UV levels (Index 5), with a burn time of 30 minutes, while February rises to a high risk (Index 7) with a shorter burn time of 25 minutes. The spring months of March and April reach very high levels (Index 9 and 10), reducing safe exposure time to just 15 minutes. The summer months, particularly May through August, present extreme UV conditions (Index 11-12) with a critical burn time of only 10 minutes, posing the highest risk for skin damage.
