Bologna has a humid subtropical climate, while summers are hot and muggy during the months of July and August the temperature rise is at its peak so much so that a number of places are closed. Holidays to Bologna in winters are simply beautiful with heavy snowfall; and though January and February feature cloudless skies, they are the coldest months. As any Bologna travel guide will warn you, Bologna tourist attractions opening times may change with the weather/season.

The best time to visit would be from March to October, it is pleasant enough to visit all the places and sit at one of the Piazza nibbling on your gelato!
