As winter deepens, people are generally concerned about a question: When is the coldest time in winter? By analyzing hot topics and hot content across the Internet in the past 10 days, we can explore this issue from multiple perspectives such as meteorological data, regional differences, and people’s experience. This article will provide you with detailed answers based on structured data.
1. Meteorological data analysis
According to data from the China Meteorological Administration and the National Climate Center, the coldest periods in winter usually occur during the "March Nine" and "Four Nine" periods, that is, the third and fourth "Nine Days" after the winter solstice. The following is the temperature data statistics for the past 10 days:
| Date | Average temperature (℃) | Minimum temperature (℃) | area |
|---|---|---|---|
| January 5 | -5 | -12 | Beijing |
| January 6 | -7 | -15 | Beijing |
| January 7 | -8 | -18 | Beijing |
| January 8 | -10 | -20 | Beijing |
As can be seen from the table, the lowest temperature in Beijing reached -20°C on January 8, which was the coldest day in recent times. This data confirms the folk proverb "three ninety-nine times walking on ice".
2. Comparison of regional differences
China is a vast country, and the coldest periods vary in different regions. Here are the coldest period statistics for major cities:
| city | coldest period | Historical minimum temperature (℃) |
|---|---|---|
| Harbin | mid january | -38 |
| shenyang | late january | -33 |
| Shanghai | late january | -10 |

It can be seen from the table that the coldest period in northern cities is generally earlier than that in southern cities, and the minimum temperature difference is significant. The coldest period in Harbin is usually in mid-January, while the coldest period in Guangzhou is concentrated in early January.
