Focusing on temperature, precipitation, wind direction and wind speed, the climatic changes at Mount Emei National Reference Climatological Station from 1951 to 2023 are investigated. The results show that: (1) An upward trend in average temperatures, as well as extreme maximum and minimum temperatures, with autumn exhibiting the most rapid warming rate, extreme minimum temperatures at Mount Emei become more sensitive to climate change. (2) Annual precipitation shows a significant decreasing trend overall, though spring precipitation displays a slight increase. Summer precipitation substantially exceeds that of other seasons. (3) Wind speeds generally exhibit a declining trend, while easterly winds show a slight increasing tendency. (4) The dominant wind direction at Mount Emei was southeasterly during 1953—1981, followed by a notable shift in prevailing winds thereafter.
