Abstract：In order to investigate the spatio-temporal distribution characteristics of high temperature and drought during the summer of 2022 in Chongqing，this study compared the daily precipitation and daily maximum temperature from July to August 2O22 there with the historical summer high-temperature days during drought years，and employed the inverse distance weighting interpolation method and time series analysis to analyze the summer drought characteristics at 34 meteorological stations there，as well as the spatio-temporal characteristics of daily precipitation and daily maximum temperatures at typical stations， and the spatio-temporal characteristics of summer high-temperature days.The results show that the extreme summer drought in Chongqing in 2O22 lasts 6O days，with longer，more frequent，and more severe drought periods in paralled ridge-valley region and the hilly areas of central Sichuan than other areas.In the summer of 2O22，Chongqing experiences an extensive and prolonged severe drought，so it is recommended to comprehensively consider both engineering and non-engineering measures to enhance the regional drought resistance.
