Abstract: In the summer of 2023 (from June to August), the national average air temperature was 22.1℃, which was 0.8℃ higher than the same period from 1991 to 2020. And it’s ranking second highest among the same periods since 1981. The national average precipitation was 311.3mm, which was 3.3% lower than the same period from 1991 to 2020. But the spatial distribution of the national average precipitation was greatly different. The national average sunshine duration was 661.6h, which was 1.7% lower than the same period from 1991 to 2020. During the summer harvest and planting season, the progress of summer harvest and planting was generally smooth with the fine weather. With the continuous rainy weather, the summer harvest of Henan and Shaanxi province was hindered to some extent. In summer, most agricultural areas had the suitable light and temperature and the abundant precipitation, which were conducive to the formation of high-yield groups of autumn crops. At the same time, some farmland suffered from waterlogging disasters in Beijing-Tianjin-Hebei and Northeast regions as the strong rainfall. In addition, high temperatures were extreme in places such as North China, Huanghuai and Xinjiang. And the seasonal drought occurred in parts of Northern and Southwestern agricultural areas. These factors resulted in the weak growth and yield reduction of some autumn crops.
