October is a great time to visit Italy, as the weather is generally mild and pleasant. In the north, temperatures range from 44 to 64 degrees Fahrenheit, so it's wise to bring some warm clothing. Central Italy sees temperatures between 56 and 71 degrees, while the south is slightly warmer with temperatures between 66 and 74 degrees. Rain is common throughout the country, so don't forget to pack a raincoat or umbrella.
The rolling hills of Crete Senesi are particularly beautiful in October, and you may even find some warm days and almost empty beaches in the south.
