An analysis of changes in surface air temperature was carried out at stations in the Saratov region from 2002 to 2022. The study is based on the analysis of materials from longterm hydrometeorological observations carried out through the Roshydromet network, which reflects the reliability of the results obtained. The article presents a comparison of average monthly temperatures for a given period with temperature norms. A map of temperature changes was constructed. The duration of the growing season for plants was calculated and analyzed.
