Emilia-Romagna is a region of northern Italy, stretched from west to east, and occupied by the Po Valley in the central-northern area and by the Apennines in the southern part. In the east, the region overlooks the Northern Adriatic Sea. The Po river flows in the north and marks the border with Lombardy to the west and Veneto to the east.
Romagna occupies the south-eastern part of the region, and reproduces the same characteristics in small, with a coastal, a flat and a mountainous part.
Plain
In the plain, the climate is of the
semi-continental type, with cold, humid winters and hot, sultry summers.
Here are the average temperatures of Bologna, the regional capital, located in the central-eastern part.

Precipitation in the plains is not abundant, and is slightly more scarce in the eastern and northern part, far from the Apennines, where it amounts to about 650 millimeters (25.5 inches) a year, and more abundant in the western part (v. Piacenza, Parma), where it exceeds 700 mm (27.5 in) a year. In general, the rainiest seasons are spring and autumn, while in winter and in summer the rains decrease a little.
Here are the average precipitation in Bologna.

In
winter, from December to February, the western part (see Piacenza, Parma), is more cold, foggy and cloudy, and the wind is often weak or absent. The eastern part (Ferrara province and Romagna) can instead receive both the sirocco, the warm wind from the south-east, and the bora, the cold wind from the north-east. Traveling along the Aemilian Way (Via Emilia) from north-west to the south-east, the average temperature of January is 2.8 °C (37 °F) to Piacenza, 3.5 °C (38 °F) in Bologna, 4.5 °C (40 °F) in Forlì and 4.7 °C (40.5 °F) in Rimini.
During
cold waves, which are becoming rarer due to global warming, the temperature can drop to -10 °C (14 °F) or even less. In general, the lowest temperatures are recorded in the western provinces (Piacenza and Parma), where cold air stagnates more. In January 1985, the temperature dropped to -15 °C (5 °F) on the Adriatic coast and to -20/-25 °C (-13/-4 °F) in the rest of the plain.
Snow is more frequent in the western part of Emilia-Romagna than in the eastern one, but in the latter, sometimes there can be abundant snowfall, during the most intense cold waves (thanks to a phenomenon similar to the Lake-Effect Snow that occurs in the Great Lakes of North America). In addition, it snows more in the cities located along the Via Emilia, which are close to the Apennines, than in the low plain, where the Po flows.
Traveling along the Via Emilia from north-west to the south-east, on average, more than 40 cm (15.5 inches) per year of snow fall in Piacenza, about 30 cm (12 in) in Parma, Reggio Emilia, Modena and Bologna, about 25 cm (10 in) in Forlì and Cesena, and 20 cm (8 in) in Rimini.
During the great snowfalls of February 1929 and February 2012, more than one meter (39 in) of snow fell in the Romagna plain, especially between Forlì and Cesena.
In
summer, from June to August, Emilia-Romagna is the hottest and driest region in Northern Italy. Sometimes, thunderstorms can burst, but less often than in the part of the Po Valley north of the Po (see Lombardy, Veneto).
The average temperature of July and August ranges from 24/24.5 °C (75/76 °F) on the coast (see Cervia, Rimini) to almost 26 °C (79 °F) in the central area (see Reggio Emilia, Modena, Ferrara).
There is often
oppressive heat in the lower Po Valley, far from the sea and the Apennines. The highest temperatures are recorded in the central-western part, at a certain distance from the sea, around Ferrara and in the lower plain of the provinces of Modena and Bologna. In this area, the heat records are slightly higher than 40 °C (104 °F).
In Romagna, on the other hand, the sea breeze makes the heat decidedly more bearable, except in the few days in which the sirocco blows.
The
sea on the Romagna coast is warm enough to swim in from July to September, while in June it is still a little cool. Here is the average temperature of the sea in Rimini.

Apennines
On the Tuscan-Emilian Apennines, the climate is
temperate humid at intermediate altitudes and cold in the high mountains. The temperatures decrease with increasing altitude, moreover, precipitation becomes more abundant, and in certain areas it exceeds 1,500 mm (59 in) per year. In winter, abundant
snowfalls may occur, while in the summer, afternoon thunderstorms are more frequent than in the plains. Even the
wind blows more often, and can be strong, especially on the mountain ridge, where mild, humid air can arrive from the Tyrrhenian Sea.
Here are the average temperatures in
Sestola, located at 1,000 meters (3,300 feet) above sea level in the Modenese Apennines.

Best Time
To visit the
cities located in the plain, you can go from mid-April to mid-June. September is also a good month. However, you have to take into account a few rainy days on both periods. In summer it can be very hot, while winter is often cold and humid, with poor sunshine and sometimes fog.
For a
beach holiday on the Riviera Romagnola, you can go to the summer, from June to August, with a preference for July and August, given that they are the warmest and sunniest months, and in which the sea is also warmer.
On the
Apennines you can go both in winter, perhaps to ski, and in summer, perhaps to trek in the mountains and to escape the heat of the plain. In winter, on the ski slopes there is not always snow, especially in November and December, that is, at the beginning of the season.
