With the developing world, deterioration in natural balances has occurred, leading to climate change, which is one of the important problems for the world. Drought, which occurs as a result of climate change due to global warming in the world and in our country, causes precipitation to fall below the long-term average values within a certain period. Turkey is located in the semi-arid, semi-humid mid-latitude region. Therefore, drought, which is one of the devastating effects of climate change, poses an important problem for our country, some of which is in the semi-arid climate zone. In this study, meteorological drought analysis was performed in the province of Kahramanmaraş, which is located in the Mediterranean region, using the Standardized Precipitation Index (SPI) method in 3, 6, 9 and 12 month time periods. The Average Monthly Total Rainfall Amount between 1990-2020 of Afşin Elbistan, Göksun and Kahramanmaraş-central meteorological observation stations was used. As a result, an increase was found especially in drought periods of 2000 and later for 4 meteorology stations according to all time scales. While long years of dry periods were found in Kahramanmaraş-center and Göksun region according to SPI values, no significant changes were found in annual total precipitation amount data during the dry periods in Kahramanmaraş-centre. This shows that the amount of precipitation has not changed, while the number of rainy days has decreased. It was found that the dry periods in Afşin and Elbistan region were relatively shorter. Turkey is located in the semi-arid semi-humid middle latitude region. Therefore, drought, which is one of the devastating effects of climate change, poses an important problem for our country, some of which is in the semi-arid climate zone.
