Is slight cold and severe cold the coldest time?

Slight cold and severe cold are the coldest times.

The coldest time of the year is March 9, as the saying goes: March 9 walks on the ice, and the slight cold solar terms enter March 9 and April 9, marking the coldest day of the year. Although the solar terms of light snow and heavy snow are all named after snow, slight cold is the coldest solar term. Slight cold is the 23rd solar term in 24 solar terms and the 5th solar term in winter.

Cold air is cold for a long time, and slight cold means that the weather is cold but not extreme. Like severe cold, mild summer heat, severe summer heat and intense summer heat, it is a solar term indicating temperature change.

According to China's long-term meteorological records, the slight cold solar terms in the north are colder than the severe cold solar terms, and there is a saying in the north that "slight cold is better than severe cold"; However, for most parts of the south, the lowest temperature in the whole year will still appear in the great cold solar terms.

Which is colder, slight cold or severe cold?

As the name implies, the ancients have divided it into sizes according to their names, with great cold being the coldest and slight cold second. However, according to China's long-term meteorological statistics, the annual minimum temperature in most parts of the south appears in the severe cold solar terms, but not in the north. In northern China, there is even a saying that "slight cold is better than severe cold, which is common but not rare". Therefore, in the north, slight cold is actually colder than severe cold, but the specific situation should be judged according to the actual weather conditions.
