For its geographical position the area of Prijedor Municipality falls under moderate-continental climate. Climate is modified primarily under influence of relief, and special part in it stems from feature of Kozara Mountain which fences off most of the vast Prijedor area from direct influence of air mass coming from Pannonia basin. Valley of River Sana and River Gomjenica also open up encircled valley to streams of air from the south-east and southern side. These streams greatly influence higher mobility of air masses in the lower parts of Prijedor encircled valley - which is characterized by a very frequent and long-term mist.
