Due to the large size of the peninsula and the largely mountainous inland conformation, the climate in Italy is very diverse. In most of the northern and central interior regions, the climate ranges from humid subtropical to humid continental and oceanic. The climate in the geographical area of the Po Valley is mostly continental, where the winters are cold and the summers hot.
In Liguria, Tuscany and the majority of the south, coastal areas comply in general with the stereotype of the Mediterranean climate. Conditions in the coastal areas of the peninsula can be very different from those in the high altitudes and valleys of the interior, especially during the winter months when the high altitudes are cold, humid and often snowy. Coastal areas have mild winters and warm and generally dry summers, although the valleys of the plains can become quite warm in summer. Temperatures in winter typically range from 0 °C (32 °F) in the Alps and up to 12 °C (54 °F) in Sicily, while average temperatures in summer are between 20 °C to over 25 °C .
