Sesame is one of the important oil seed crops grown for high-quality oil. Its growth, development, and yield are significantly affected by changing climate conditions. Evaluating sesame climatic suitability crucial to optimize cultivation patterns planting distribution, aid strategic decision making future agricultural adaptation. Based on theory fuzzy mathematics method, in this study, we established temperature, precipitation, sunshine, comprehensive model. Then, assessed spatial distribution chronological changes under two periods, 1978–1998 (earlier 21 years) 1999–2019 (latter years). The results showed that compared with meteorological data earlier years, mean temperature during sesame-growing season latter years increased from 24.48 °C 25.05 °C, cumulative precipitation 744.38 mm 754.81 mm; however, sunshine hours decreased 6.05 h 5.55 h. Temperature, main sesame-producing areas China all had a downward trend. north higher than south, while an uneven distribution. area high-temperature high-precipitation 43.45 × 106 ha 46.34 3.20 7.97 ha, respectively, whereas high-sunshine 4.04 2.09 ha. change was more beneficial northeast Anhui where high clearly expanded, eastern Jiangxi general increased. In contrast, it worth noting northern Henan low Hubei Our have implications improving production cope ongoing change.
