2023年夏季（6—8月）大气环流特征为:北半球极涡呈现偶极型分布，极涡强度较常年偏弱，欧亚地区及西北太平洋500 hPa槽脊位置与常年相近，副热带高压较常年平均偏西且略偏南，强度偏强，范围偏大。6 月，我国东部和北部近海海域出现3次海雾过程，7月和8月无大范围海雾过程。2023年夏季西北太平洋和南海生成台风10个，个数较常年同期偏少，平均极值强度显著偏强。6月生成1个远海转向台风；7月生成3个台风，其中2个台风登陆我国；8月台风活动频繁，生成台风6个，其中有两个在9月登陆我国。2023年夏季全球其他海域有20个编号热带气旋生成。2023年夏季我国近海出现了6次8级以上大风过程，其中热带气旋大风引发5次，江淮气旋入海引发1次。浪高超过2 m 的大浪过程发生12次。2023年夏季西北太平洋和南海海表温度较常年平均偏高，台风活动对海浪和海表温度分布影响显著。
In the summer (June to August) of 2023, the atmospheric circulation features are as follows: in the Northern Hemisphere, the polar vortex exhibits a bipolar distribution with weakened intensity compared to the annual average. The synoptic mid-latitude circulation on 500 hPa in the Eurasian region and the northwestern Pacific are similar to the annual average. The subtropical high is located further west and slightly south of its annual average position, with greater intensity and a larger coverage area. In June, coastal areas in the eastern and northern parts of China experienced three processes of sea fog, while there is no extensive sea fog events observed in July and August. Throughout the summer, the northwestern Pacific generated ten typhoons, which is fewer than the annual average, with significantly stronger average maximum intensity. More secifically, in June, one typhoon generated offshore. In July, three typhoon formed, among which two typhoons made landfall in China. In August, typhoon activity was frequent, six typhoons formed and two out of which made landfall in China in September. Additionally, there were 20 named tropical cyclones in other basins. During the summer, China's coastal regions experienced six episodes of severe winds exceeding wind scale 8 (B.F.), with five of them attributed to tropical cyclones and one to the Jianghuai cyclone entering the sea. There were 12 occurrences of waves higher than 2 meters. In the summer, sea surface temperature in the northwestern Pacific and South China Sea is generally higher than the annual average. Typhoon activity significantly influenced the distribution pattern of wave height and sea surface temperature.
