The best time of the year to visit Florence, Italy, is April through May and September through mid-October. These months provide the most comfortable overall weather while having smaller crowds than what you’ll find during the peak summer travel season.Summer in Florence gets too hot, and the locals typically take a month-long vacation in August, meaning the month is not an ideal time of year to go. Visiting during the winter can be a budget-friendly option, but it can get a bit cold and rainy at times.
