Climate parameters such as precipitation and temperature, which undergo long-term changes, have negative effects on the hydrological cycle and, consequently, on human life. In our country where climate change has an impact, hydro-meteorological studies are of significant importance to ensure the optimal utilization of water resources. In this study, precipitation data from seven meteorological observation stations located in Ankara province were analyzed seasonally and annually to identify trends. The Petitt Homogeneity Test, Mann Kendall Test, and Innovative Trend Analysis were employed for the analyses. According to the homogeneity test, a breakpoint was observed only in the annual results of one station. As for the seasonal results, breakpoints were detected in one station each for the winter and summer seasons. The Mann Kendall trend analysis revealed only one station with a trend, both in the annual and seasonal datasets. More distinct results were obtained from the Innovative Trend Analysis test. In the annual data, a decreasing trend was identified in one station, while an increasing trend was observed in five stations. Seasonally, three stations showed a decreasing trend in the autumn, and four stations exhibited an increasing trend. The results obtained from the three methods were examined to evaluate the current precipitation trends in the region.
