Italy's Climate: Weather Characteristics by Season and Region

Italy is located in a subtropical Mediterranean climate zone, characterized by mild winters and hot summers. However, due to the country's elongated shape from north to south (over 1,100 km) and complex terrain, the climate varies significantly across different regions.

Factors Affecting Italy's Weather

Several key factors shape the climate:
