Romania's geographic situation in the southeastern portion of the European continent gives it a climate that is transitional between temperate regions and the harsher extremes of the continental interior.

In the centre and west, humid Atlantic climatic characteristics prevail; in the southeast the continental influences of the East European Plain make themselves felt; and in the extreme southeast there are even milder sub-Mediterranean influences. This overall pattern, however, is substantially modified by relief, and there are many examples of climatic zones induced by altitudinal changes.

The average annual temperature is 52º F (11º C) in the south and 45º F (7º C) in the north, although, as noted, there is much variation according to altitude and related factors. Extreme temperatures range from 111º F (44º C) in the Baragan region to -36º F (-38º C) in the Brasov Depression.

Average annual rainfall amounts to 26 inches (660 millimetres), but in the Carpathians it reaches about 55 inches, and in the Dobruja it is only about 16 inches.

Humid winds from the northwest are most common, but often the drier winds from the northeast are strongest. A hot southwesterly wind, the austru, blows over western Romania, particularly in summer. In winter, cold and dense air masses encircle the eastern portions of the nation, with the cold northeasterly known as the crivat blowing in from the East European Plain, while oceanic air masses from the Azores, in the west, bring rain and mitigate the severity of the cold.
