In Laisu, China, being aware of the UV Index is crucial for protecting your skin from harmful UV rays. Understanding UV levels helps in preventing sunburn and maintaining overall skin health, particularly in a region characterized by a Cfa climate that often brings intense sunlight. With midday UV Index levels soaring to 11, the risk of overexposure is significant. Staying informed about these levels not only safeguards your health but also enhances your outdoor experiences in this vibrant city.

Early morning hours start gently, with a mere 1 at 07:00 AM gradually rising to a moderate 4 by 09:00 AM. As the sun climbs higher, the index escalates to 9 by 11:00 AM and hits its zenith of 11 at 1:00 PM, indicating a critical level of UV radiation. Following the peak, there’s a noticeable decline; by 15:00 PM, the index dips to 7, continuing to taper off to 3 by 5:00 PM, before settling back to 1 as the evening sets in. Be sure to protect your skin during those peak hours to enjoy the sunshine safely!
