Geography of Romania
Extending inland halfway across the Balkan Peninsula and covering a large elliptical area of 237,499 square kilometers (91,699 sq. mi.), Romania occupies the greater part of the lower basin of the Danube River system and the hilly eastern regions of the middle Danube basin. It lies on either side of the mountain systems collectively known as the Carpathians, which form the natural barrier between the two Danube basins.

Romania's location gives it a continental climate, particularly in the Old Kingdom (east of the Carpathians and south of the Transylvanian Alps) and to a lesser extent in Transylvania, where the climate is more moderate. A long and at times severe winter (December-March), a hot summer (April-July), and a prolonged autumn (August-November) are the principal seasons, with a rapid transition from spring to summer. In Bucharest, the daily minimum temperature in January averages -7oC (20oF), and the daily maximum temperature in July averages 29oC (85oF).
