Understanding the UV Index is crucial for residents and visitors in Jiusuo, China, where the climate can expose you to significant sun radiation, particularly during the peak hours of the day. As temperatures rise and the sun's rays become more intense, awareness of UV levels can help you take necessary precautions to prevent sunburn and maintain long-term skin health. With a typical UV Index that peaks at 14 around noon, Jiusuo’s moderate climate presents distinct challenges, making it essential to be informed about daily UV variations to enjoy the outdoors safely and protect your skin.
The UV Index today showcases a dynamic journey through the hours, beginning with a gentle rise at 07:00 with a safe level of 1. As the sun climbs higher, a noticeable increase brings the index to 4 by 09:00, before peaking at an intense 14 around 13:00. This midday high of 13 is particularly important, signaling a period of significant UV radiation where protective measures are advisable. As the afternoon progresses, the index starts to dip, dropping to 6 by 16:00 and stabilizing at a comfortable 1 by 18:00. This hourly pattern highlights the importance of staying sun-safe during the intensity of the midday sun, while enjoying lower UV levels later in the day.

Throughout the year, UV Index levels exhibit notable seasonal fluctuations, with highest risk periods occurring from February to September, where values remain consistently in the extreme range (12-14) and the burn time is as short as 10 minutes. Of particular concern are the months of March, May, July, and August, which all peak at a UV Index of 14. As we transition into October, the UV Index decreases slightly to 12, still indicating extreme risk. In contrast, the winter months of November and December feature a much lower UV Index (9 and 8 respectively), categorized as very high, allowing for a slightly longer burn time of 15 minutes. Residents and visitors alike are strongly advised to take precautionary measures during high-risk months, including wearing sunscreen, protective clothing, and sunglasses, and seeking shade when outdoors, especially during midday hours. Staying informed and vigilant can greatly reduce the risk of skin damage from UV exposure.
