If you're looking for a warm and sunny destination in Italy during the month of October, then you should head south. Southern Italy is the warmest part of the country during this time of year, with temperatures ranging from 66 to 74 degrees Fahrenheit. Matera is a unique city in Italy, but its climate can be unpredictable. While September may still be hot and summery, October usually marks the start of fall, with temperatures dropping across the peninsula and a greater chance of rain.
It's important to be prepared for all types of weather when visiting Italy in October. You'll need sunglasses and an umbrella handy, just in case. Northern Italy, including the Milan region, experiences average temperatures between 44 and 64 degrees Fahrenheit. Be sure to pack some warm sweaters or sweatshirts if you're visiting the mountains or northern cities.
Central Italy, including Rome, has temperatures that range between 56 and 71 degrees. Although Europeans tend to avoid the beaches during this time of year (they think it's too cold and they've already had their beach vacation in August), visitors from colder climates will love finding warm days and almost empty beaches. Two other must-see places in Trieste are Piazza Unita d'Italia, probably the most beautiful square in Italy that opens up to the Adriatic Sea, and Miramare Castle, located right on the coast.
