Spring (April to June) and early autumn (September to October) are the sweet spots: mild days, lively piazzas, and the food markets at their best. Summer is hot and humid, with July and August temperatures often above 32C and many family-run trattorias closing for a couple of weeks in August. Winter is cool, foggy, and atmospheric, and it is also truffle and tortellini-in-brodo season, when the porticoes come into their own. Time a visit around the Bologna Estate cultural program in summer, or the food-focused events tied to nearby harvests in autumn.

Bologna Guglielmo Marconi Airport (BLQ) sits about 6 km northwest of the center; the Marconi Express monorail runs to the central train station in roughly 7 minutes for around 11 euros. Bologna Centrale is a major high-speed rail hub, with Frecciarossa and Italo trains reaching Florence in about 37 minutes, Milan in around an hour, and Venice in under 90 minutes, which makes day trips effortless. The historic center is small, flat, and made for walking, so skip taxis and rental cars (much of the core is a restricted ZTL traffic zone with fines for unauthorized driving). City buses run by TPER cover longer hops, and ride-hail apps are limited, so lean on your feet.
