October is a great month to visit Italy and enjoy the warm weather, especially in the south. The average temperatures for October in cities and vacation spots across Italy are listed below in both Celsius and Fahrenheit. In northern Italy, temperatures start to rise in spring, from the mid-fifties to the mid-seventies. However, it is still recommended to wear layers in case of colder periods.
Meanwhile, rainfall increases in the south, but temperatures remain warmer. Two of the must-see places in Trieste are Piazza Unita d'Italia, which is considered one of the most beautiful squares in Italy that opens up to the Adriatic Sea, and Miramare Castle, which is located in an impressive spot right on the coast. Overall, the best time to visit Italy is during spring and autumn when temperatures are pleasant and there are fewer people.
