Yasuj is the capital of Kohgiluyeh and Boyer-Ahmad Province. Yasuj is an industrial city in the Zagros Mountains of southwestern Iran. The people of Yasuj speak Luri, one of the western Iranian languages. Yasuj has the typical continentally-influenced Mediterranean climate of western Iran, though because of its location in the direct line of rain-bearing winds from the Persian Gulf it is the wettest Iranian city south of the Elburz Mountains.
