Italy is at its best in spring (April-May) and autumn (October-November). During these seasons, the scenery is beautiful, the temperatures are pleasant and there are relatively few crowds. Try to avoid August, as this is the time that most Italians take their vacations, and many shops and businesses are closed as a result.
Weather – Italy’s climate varies from north to south and from lowland to mountain top. Temperatures at sea-level tend to be similar around the country, with altitudes creating steep changes between summer and winter.
Winters are long and severe in the Alps, with snow falling as early as mid-September. Storms develop in spring and tend to last to autumn, making summer the wettest season. The northern regions experience chilly winters, hot summers and regular even rain distribution, while conditions become milder as you head south. The sirocco, the hot and humid African wind that affects regions south of Rome, produces at least a couple of stiflingly hot weeks in summer.
