Italy weather: is the warmth of the Mediterranean the reigning factor here or is the bitter coldness of the Alps mountains range the prevailing theme? As a matter of fact, depending of course which part of the country you place under the microscope, both are known to reign supreme.

Because of its unique position – juxtaposed between the Adriatic Sea to the east and the Mediterranean Sea to the south, with Mont Blanc in the Alps mountain range forming a protective shield from the cold winds from the North – Italy weather enjoys a diversity of climate conditions, which effectively make it a favorite holiday destination for both the summer and winter tourist seasons. In a nutshell, the weather in the northern mountainous region is cold, while the hills and the plains of the south have a much hotter and drier weather.

Occasionally though, because of the warm, humid wind known as the sirocco and its profound effect on most aspects of Italy weather, all parts of the country  experience very high temperatures. Originating over North Africa and acquiring its humidity over the Mediterranean, the sirocco blows over Italy during the summer season, sometimes even in autumn when it often ends with very heavy rain accompanied by thunder.

The best way to come to understand the many variations of Italiy weather is to divide the country into three geographical regions, each with its distinct climate peculiarities: the southern side of the Alps where Italy borders France, Switzerland, Austria, and Slovenia; the great plain of the Po valley from Turin to Venice; and the long and mountainous peninsula of central and southern Italy together with the large islands of Sardinia and Sicily.

There are obviously a lot of considerable differences in temperature between the north and the south, especially during winter and less during the summer season: while some winter days snow falls in Milan and  the temperature drops to a freezing –2 °C, over in Rome it’s 12 °C and in Cagliari 22 °C.

Alpine Italy

Not surprisingly, the weather in the Italian Alps, whose mountains peak to 3,000m above water, is almost identical to that of the Swiss and Austrian Alps, the only distinctive difference being the heavier precipitation that the Italian side enjoys. Furthermore, the lower slopes and valleys of the Italian Alps are also a little warmer both in summer and winter.

The region of lakes Maggiore, Como, and Garda enjoy the mildest winters as well as the warmest and sunniest summers, averaging three to four hours of sunshine per day during winter, and up to nine hours in summer. The Alpine Alps are considered to be a summer rainfall season, with thunderstorms making a frequent appearance during, autumn, spring as well as summer.

Winters in the North are cold, with temperatures dropping quickly and averaging -8oC in the alpine ski resorts.

During summer, you will find that Northern parts of Italy, warm as they may be, still experience the occasional rainfall, while the central region is gripped by a wave of humidity, and the south is scorched by the dry heat. Although the best time to visit is in spring or autumn when the weather is still good, most people choose to pay Italy a visit between June and August. The best time for a swim is definitely the period between June and September, when the sea is at its warmest. Needless to say, because of the peculiarities of Italy weather, it’s best to do your research and plan carefully before taking the plunge and booking your tickets.
