Is the first frost frost-free?

It's not good to have no frost at first.

According to long-term observation, whether there is frost at present when the first frost solar term comes has a certain relationship with the future weather and crops. The phrase "the first frost sees the frost, and Man Cang is in the next year" means that if the first frost sees the frost in the solar terms, it indicates that the next year will be a good year with good weather; If there is no frost at the beginning of the solar term, it indicates that the weather will be less rainy, dry and rainy in the future, and the harvest will be worse.

Climatic characteristics of the first frost.

During the first frost period, it usually lasts from late June 10 to1early October 10. As dry and cold air gradually dominate the whole country, warm and humid air is marginalized, and many weather with characteristics of summer and early autumn exits, so the weather is relatively simple.

As far as the north is concerned, after the cold air, the sky is still high and the clouds are light, giving people a deep impression of cooling down again and again. In addition to the northeast, northwest and other places in the north or higher altitude, everything is withered and snowflakes are flying, and most areas in the south are autumn colors of "frosty leaves are redder than February flowers".
