The paper considers the dynamics of drought periods based on meteorological data for a multi-year period. The research area covers the basins of the Sokolovsky reservoir and the Taganrog Bay. In the course of the study, the following tasks were performed: climatograms were constructed, a correlation analysis of the course of the total amount of precipitation and the course of average annual temperatures was performed, the deviation of air temperatures from the climatic norm for the considered areas was revealed. The tendency to increase the dry period in the Rostov region from north to south has been revealed, which may have an adverse effect on the hydrological regime of water bodies.
