中国天气网基于近十年气象大数据发布统计结果，对全国主要城市的秋高气爽日数进行了排名1。兰州以27.2天的秋高气爽日数高居全国主要城市榜首，银川、太原、济南和乌鲁木齐紧随其后1。前十名城市全部被北方城市包揽1。
从季节推移来看，不同地区体验秋高气爽的时间节奏有所差异1。西北和东北部分地区率先在9月进入秋高气爽状态，而华北和黄淮一带的秋高气爽集中时段则落在10月1。10月成为全国大部分城市体验秋高气爽的最佳时段1。相比之下，南方城市的舒适期相对较晚，昆明、南昌、合肥、南京和武汉等地到11月才迎来秋高气爽的黄金期1。
北方更易形成秋高气爽天气，主要因为冷空气影响早、水汽少、云量低1。这些城市整个秋天里有20天以上都是秋高气爽的日子1。
China Weather Network has released a statistical analysis based on meteorological data spanning the past decade, identifying which cities across the country experience the most days of ideal autumn weather characterized by clear skies, low humidity, and comfortable temperatures.1
Lanzhou emerges as the national leader with 27.2 days of such optimal autumn conditions, according to the data.1 Yinchuan, Taiyuan, Jinan, and Urumqi follow closely behind, with all ten top-ranking cities concentrated in northern China.1 The northern regions benefit from earlier cold air influence, lower atmospheric moisture, and reduced cloud cover, which collectively create conditions more favorable for this type of pleasant weather.1
The timing of peak autumn comfort varies across the country.1 Northwestern and northeastern regions begin experiencing these ideal conditions as early as September, while the North China Plain and Huai River regions typically reach their most comfortable period during October.1 Southern cities including Kunming, Nanchang, Hefei, Nanjing, and Wuhan encounter their most pleasant autumn days later in November.1 These cities generally enjoy more than 20 days throughout the entire autumn season with such favorable weather conditions.1
