In 2026, July and August remain the most crowded months in Florence, Italy. These months coincide with the peak of international summer vacations and school breaks, leading to overwhelming tourist numbers and 2–3 hour lines at major sites like the Uffizi Gallery and Accademia. August is particularly intense; while it is a peak travel month, many local Florentines leave for their own vacations during the "Ferragosto" period (mid-August), which can mean fewer local shops and restaurants are open despite the massive crowds. June and September are also highly congested "high season" months. For those wishing to avoid the peak "crush," visiting during the shoulder seasons of April, May, or October provides a more balanced experience with manageable crowds and pleasant weather. If your goal is to avoid crowds entirely, the "low season" from November to March is best, though you will trade the warm weather for shorter days and occasional Tuscan fog and rain.
