Favorite thing: If I had the choice of being in Florence in summer or winter, the end of November, December would win hands down. It might be a little chilly (sometimes very chilly) in the morning and evenings, but Florence in all it's Christmas glory is enough to warm you up and refresh your view of beauty. There is a buzz in the air and a sense of anticipation each dusk and evening as people, mostly locals, rush around the centre with their hands full of shopping bags. They start to put out the Christmas lights at the end of November and the city centre becomes even more special.
First, I am a cold weather person by nature, meaning I would much rather freeze than sweat. That is why I loved Florence so much. I got to tour the city twice, once in October and again in February. I cannot even imagine being in line for the Uffizi in August, with the multiple hour wait, heat and general icky feeling. October was really manageable lines and cool weather, but my favorite was February, when there were zero lines, cold, crisp weather and a general lack of tourists in my way.
I know most people's vacation dates are set to be in the summer, but if you prefer colder weather, less waiting, and "truer" Florence life, come in the winter time.
High season: May - September
Shoulder season: October-November & March- May
Low Season: December-February
Give yourself at least five days here. Especially if you have any interest in art history. Take your time, and make an itinerary. There is a tremendous amount of things to see.
Fondest memory: The Churches of Florence are the most beautiful. Each has it's own individual charachter.
