Being located within the boundaries of Upper Murat-Van Section of Eastern Anatolia on an area of 11. 376 km², the province of Ağrı roughly covers the depression areas extending in the direction of east-west and the highlands surrounding those areas. Depending on the topographic qualities of the area, it is seen that climatic elements also differ within short distances. This difference, which is especially observed under heat and rainfall conditions, affects the climatic type in the same way. There is no self-contained study on the climatic features of the (general) province of Ağrı. This study partially aims to overcome this deficit. While examining the features of the climate, which dominates in the study field and greatly affects the lifestyle of locals, we used not only the long-term observations of Ağrı meteorology statiton, but also the observation data of other meteorology statitons that are located within the boundaries of the province. According to the data of meteorology statitons that make long-term observations in Ağrı (Ağrı, Doğubayazıt and Patnos), the mean yearly temperature of the province varies between 6,2 and 9,2°C. Examining the rainfall features of the study field according to the long-term observation results (1960-2012), the mean yearly rainfall was determined as 521,8 mm by Ağrı, 333,2 mm by Doğubayazıt and 468,3 mm by Patnos. While this value is averagely 577,2 mm in Eastern Anatolia, it is 643 mm across the country. Altitude and topographic conditions are apparently effective upon the rainfall features of the province of Ağrı, which has a rainfall under the region and country average. Analyzing the climatic elements of the province of Ağrı, it is observed that it generally has the climatic features of the Eastern Anatolia Region due to its geographical position, except for some little differences in local scales. According to the De MARTONNE formula that is used to determine the rainfall efficiency of Ağrı, it has a semihumid transition climate that is generally observed between humid climates and semiarid climates; according to the ERİNÇ Formula, it has a semihumid climate; and according to the THORNTHWAITE climate classification, Ağrı has a semihumid, terrestrial, first-order mesothermal climate lacking water in summer at a moderate rate.
