This study aims to analyze the past temperature and precipitation of Kunduz river basin which is located in the northern part of Afghanistan. The annual and seasonal temperature and precipitation of five weather stations at the basin analyzed over period of 1961-2014. The Mann-Kendall and Sen’s slope statistical tests were used to detect the positive or negative trend of the past maximum temperature (Tmax), minimum temperature (Tmin) as well as precipitation (Precip). The overall Tmax and Tmin showed warming over study period. The statistical results demonstrated a considerable increase of temperature at the fall and summer seasons. The Tmin indicated highest warming in autumn season at the rate of 0.02˚C/Year, 0.02˚C/Year and 0.03˚C/Year at Bamyan, Taloqan and Kunduz weather stations respectively over period of 1961-2014. However, the precipitation depicted declining at the majority weather stations. The upper catchment of basin represented decrease of precipitation. The most significant downtrend of annual precipitation obtained at the Bamyan and Taloqan meteorological stations. In contrary, Kunduz station indicated rise of annual precipitation pattern. The comparison of seasonal time series of precipitation demonstrated larger drop in summer months. The rate of decline 0.07 mm/year, 0.026 mm/year and 0.08 mm/year at Baghlan, North Salang and Kunduz stations respectively. In addition, both increase of temperature and decrease of precipitation is considerable concern regarding to irrigation water at summer time
