I’m will be in Florence next year

The historical averages for the end of March are18-19C (9C at night). This year it was only 16C on the 27th, but 27C on the 30th. The overnight temperatures varied from 2C to 13C. I would need a coat!

I would definitely recommend bringing a coat and scarf as the temperature tends to really vary. You'll want to layer up in case it gets warm during the day and bring waterproof shoes as that is typically a rainy time. It's a nice period to be here though :)
