The three warmest cities in Italy are Messina, Agrigento, and Reggio Calabria.
Italy is one of the warmest countries in Europe and one of the most popular choices to seek summer sun or go for a quick winter getaway. When you visit Italy, you can count on a warm welcome. With fabulous food, medieval charm, and beautiful coastal areas such as the globally known Amalfi Coast, Italy attracts millions of visitors (some of whom end up moving to the country).
In this article I’ll share with you my list of the warmest Italian cities with at least 50,000 residents. I’ll cover the top 10 in more detail and then present the entire ranking in a table with 125 major cities in the country.
