The township of Kahnooj is so located that to its north is Jiroft, to the east is within the limits of the vicinity of Jazmoorian in the province of Sistan Va Baluchestan, and to its western and southern sections is the province of Hormozgan. Kahnooj experiences hot weather with scanty rainfall, which is mostly in the form of thunder squalls. The Halil Rood River is the only permanent river in this township.
Due to the presence of underground waters around the Hamoon Jazmoorian, and fertile soil, animal husbandry and cultivation are vital factors here.
