Understanding the UV Index is essential for residents and visitors in Wentang, China, as it plays a crucial role in maintaining skin health and preventing sunburn. With a humid subtropical climate (Cfa), Wentang experiences significant UV exposure, especially during peak hours when indices can soar to 13 at midday. Being aware of these levels not only helps you enjoy outdoor activities safely but also safeguards against the long-term effects of sun damage, making UV Index awareness a vital part of your daily routine in this vibrant locale.
The UV Index rises sharply as the day progresses, peaking in the early afternoon. At 07:00, it starts at a mild 1, but by 09:00, it escalates to 5, signaling the arrival of more intense sunlight. 10:00 sees the index reach 8, and by 11:00, it hits a formidable 11, indicating high exposure risk. Just one hour later, the UV Index reaches its zenith at 12:00 with a striking 12, and the maximum is recorded at 13:00 at 13. However, after this peak, UV levels begin to descend, dropping to 11 by 14:00, and gradually falling to 8 at 15:00. As the sun sets, the UV Index dwindles to 5 by 16:00, and finally tapers off to 3 at 17:00, before returning to a safe 1 from 18:00 onwards. It's a day to heed sun safety, particularly during those intense midday hours!
