在中国，一月堪称全年气温的冰点，是全国范围内最为严寒的月份。绝大部分地域在冬季时节都体验着极致的寒冷，唯有南方部分城市，如广州、香港、澳门以及深圳等地，由于气候的特殊性，几乎感受不到传统意义上的冬季寒意。
中国北方地区，尤其是哈尔滨、北京和天津等地，冬季时常降雪，且雪量往往在月末达到峰值。然而，受北方地区气候干燥的影响，降雪虽然频繁，但实际积雪厚度并不显著。
值得注意的是，尽管南方地区气温相对北方更为温和，但中国中部以及长江三角洲区域在冬季时节同样寒冷刺骨。这主要归因于湿度因素，湿冷天气往往会加剧体感温度，使人倍感寒冷。

January holds the title of the coldest month throughout the year in China. The majority of regions across the nation experience the harshest winter conditions during this period, with the exception of certain southern cities such as Guangzhou, Hong Kong, Macao, and Shenzhen, which due to unique climatic characteristics, rarely encounter the traditional winter cold.
Snowfall is a frequent occurrence in Northern China, particularly in cities like Harbin, Beijing, and Tianjin, where snow accumulation typically reaches its maximum by the end of the month. However, the dry climate prevalent in the northern regions limits the amount of snow that actually accumulates.
It is worth noting that although temperatures in Southern China are relatively milder compared to the north, the winter season in Central China and the Yangtze River Delta region remains bone-chilling. This is largely attributed to the influence of humidity, which often intensifies the perceived cold, making it feel even more frigid.
