Is the long summer sunny or rainy?

There is plenty of rain in the long summer.

There is a proverb that says well, "It is easy to understand literally that the plows and rakes are hung high without stopping in the long summer". If it doesn't rain on the day of the long summer solar term, then farm tools such as plows and rakes can be hung up. Broadly speaking, long summer is the filling period of crop growth, and it is also the season of spring ploughing in some northern areas, such as wheat in Huang-Huai-Hai area. At this time, it has entered the filling period and needs sufficient water to promote filling, thus increasing yield.

The proverb "When summer is sunny, there will be drought" is similar to the above sentence. Literally, if it is a sunny day in long summer, it will be dry that year. It shows that the day is sunny in summer, and then it will be sunny and rainy, resulting in relatively dry soil in the field.
