Many streets in the centre run under porticoes, so you can walk between some sights under cover. San Petronio, the Archiginnasio, the churches and the museums are indoors, which makes a wet day easy to fill. Save the Giardini Margherita and the climb of the Asinelli Tower for a dry day.
Summer afternoons are hot, with highs above 31 degrees in July and August. The porticoes give shade along many streets, but Piazza Maggiore has none, so keep outdoor sights for the morning and the hours after sunset. Churches and museums work as cool breaks in the middle of the day, and water is worth carrying.
