The Serbian climate varies between a continental climate in the north, with cold winters, and hot, humid summers with well distributed rainfall patterns, and a more Adriatic climate in the south with hot, dry summers and autumns and relatively cold winters with heavy inland snowfall. Differences in elevation, proximity to the Adriatic sea and large river basins, as well as the exposure to the winds account for climate differences. Vojvodina possesses typical continental climate, with air masses from Northern and Western Europe which shape its climatic profile. South and Southwest Serbia is subject to Mediterranean influences, however the Dinaric Alps and other mountain ranges contribute cooling down the biggest part of warm air masses. Winters are quite harsh in Sandžak because of the mountains which encircle that plateau.
