Pisa in January

April through June gives you perfect weather without summer crowds. Temperatures hover around 20°C, and you can actually get decent photos of the tower without fighting hordes of tourists. September and October are golden months. The summer heat breaks, but restaurants and attractions stay open. Plus, university students return, bringing energy back to the bars and cafes. Skip July and August unless you enjoy sweating through 35°C heat while queuing for an hour to climb the tower. Crowds peak during these months, and many locals flee to the coast. Winter works if you're chasing budget prices and don't mind gray skies. Hotels drop rates by 40%, but some restaurants close, and the tower climb gets cancelled in bad weather. December through February sees frequent rain.
