The climate of Italy is highly diverse and can be far from the stereotypical Mediterranean climate, depending on location. Most of the inland northern regions of Italy, for example Piedmont, Lombardy and Emilia-Romagna, have a humid subtropical (Köppen climate classification Cfa). The coastal areas of Liguria and most of the peninsula south of Florence generally fit the Mediterranean stereotype (Köppen climate classification Csa). Conditions on peninsular coastal areas can be very different from the interior's higher ground and valleys, particularly during the winter months when the higher altitudes tend to be cold, wet, and often snowy. The coastal regions have mild winters and warm and generally dry summers, although lowland valleys can be quite hot in summer.

Mediterranean climate Csa

It is found in all the coastal areas, excluding the north-eastern area, which fits a Humid subtropical climate. The winter average vary from 6 °C (42.8 °F), in the northern areas, to 11–14 °C (51.8–57.2 °F) in the southern islands. During the summer, averages near 23 °C (73.4 °F) in the north (Liguria), and sometimes reaching 26–28 °C (78.8–82.4 °F) in the south. Precipitations mostly during the winter. Snowfalls are rare and usually very light in the north, and almost never happen in the south. Summers are dry and hot. Main cities: Cagliari, Palermo, Naples, Rome, Genoa, Pescara.

Mediterranean mild climate Csb

This climate is found inland and at medium and high elevations in southern Italy, around 1,000 meters (3,281 ft). It is similar to the usual mediterranean climate: the summers are dry and the winters wetter, but the temperatures are lower in both seasons — around 3 or 5 °C (37.4 or 41 °F) in the winter, and between 17 and 21 °C (62.6 and 69.8 °F) in the summer. Snowfalls are more common. Main cities and towns: Potenza, Prizzi.

Humid subtropical climate Cfa

It's found in the Po and Adige's valleys in the north until low inland central and southern Italy. It's marked by hot and wet summers. The winters are more or less mild. The precipitation is higher and there is no dry season. Average temperatures are around 1°C to 6°C in the winter and more than 22°C in the summer. Main cities: Milan, Venice, Verona, Turin, Bologna.

Oceanic climate Cfb

It can be found only in altitude in the Apennines and in the alpine foothills. Summers are between 17 and 21 °C (62.6 and 69.8 °F) Main cities and towns: Aosta, Campobasso, L'Aquila, Cuneo, Sondrio, Amatrice — mild. Belluno, Breno, Feltre — severe.

Humid continental climate Dfb

It's found in the Alps, around 1,200 meters (3,937 ft) in the western side, or around 1,000 m (3,281 ft) in the eastern side. It's marked by low winter averages (between -7 and -3 °C / 19.4 and 26.6 °F) and mild summers, with temperatures average from 13 to 18 °C (55.4 to 64.4 °F). Snow is usual from early November until March or early April. Main towns: Brusson, Gressoney-Saint-Jean, Aprica, Vermiglio, Mazzin, Santo Stefano di Cadore, Claut, Resia.

Cold continental climate Dfc

In the alpine valley around 1,600–1,800 meters (5,249–5,906 ft). The winters are very cold, averages between -12 and -5 °C (10.4 and 23 °F), and summers are cool, usually around 12 °C (53.6 °F). Main towns and villages in this area: Livigno, Chamois, Misurina, Predoi, Rhêmes-Notre-Dame.

Tundra climate ET

Above the tree line in the Alps. All the months with average below 10 °C (50 °F). Villages with this climate: Cervinia, Sestriere, Trepalle.
