Italy’s climate changes with the region. Summers in northern Italy are warm and sometimes rainy. It’s humid in central Italy and hot and dry in the south. Winters are cold, damp and foggy in the north, near-freezing in the center of the country and mild in the south. Temperatures on the coast are the same regardless of their location. The mountain areas have a much bigger difference between summer and winter and snow can start falling as early as mid-September.
