Ciao Bello! If you’re thinking about visiting Italy in September, you’re in luck. September is a pleasant time to go for a couple of weeks to the land of pasta and pizza. The summer heat is starting to dwindle and the cold autumnal briskness has yet to arrive. September has near-perfect weather. 

The best part is Italy is a place for lovers. Whether you go to Venice or Florence, Rome or Naples, you will find romance wherever you go. Every winding walk is enchanting. Every monument or cultural site is awe-inspiring. Hiking through Italy’s natural parks is also breathtaking. The best is you can capture those moments all on camera.

So let’s take a look at the average temperatures, humidity, and rainfall for the month. We’ll also add some fun things to do and eat while you’re in Italy.

Average Temperature in Italy

Because Italy is such a big country and its climates are very different, Northern Italy, which is more of a continental and mountainous region, is not the same as Southern Italy, which has more of a Mediterranean climate. When it comes to September, the average temperature for Northern Italy ranges from a high of 75 degrees Fahrenheit (24 degrees Celsius) to a low of 55 degrees Fahrenheit (13 degrees Celsius). Southern Italy, on the other hand, tends to be much warmer. The average temperature ranges from a high of about 80 degrees Fahrenheit (27 degrees Celsius) to a low of about 70 degrees Fahrenheit (21 degrees Celsius). 

Sunrise is around 7:00 a.m. and sunset is at around 7:30 p.m., which gives you about 12 hours of daylight. That’s plenty of time to explore the Italian cultural sites and eat delicious pasta.

The Hottest Temperature on Record

The world is getting warmer. The weather is getting more drastic. For Italy, the summer means intense heat. The recent years have been hotter than usual, with 2023 breaking records. In September, things start to cool down. However, the hottest temperature in September ever recorded was in San Severo in September 1946, with a whopping 114 degrees Fahrenheit (45 degrees Celsius).

September in Italy is known to be a pleasant month. It’s not as hot as the summer months and it’s not as cold as January and February. It’s truly a perfect time to visit. But like in any other place, some anomalies do happen. The coldest temperature in September ever recorded was -6.2 degrees Fahrenheit (-21.2 degrees Celsius) on September 17, 2022, in Monte Rosa.

Unfortunately, this extreme weather will only increase as climate change continues to affect the world’s climate and weather patterns. This in turn will affect human and animal life. Scientists have already been seeing the effects of extreme weather when it comes to agricultural production in Italy.

Rainfall and Humidity in September

September is not prone to much rain. Italy is mostly a dry country during the summer months and so there isn’t much humidity. The average amount of rain in September is about three inches and even less in the Southern half of the country. With an average of six to seven rainy days in the whole month, September is quite dry. 

UV Index in September

Italy is located in southern Europe, which means it gets more sun than northern European countries. Because September is a hotter month, the sun does shine quite brightly during the daylight hours. In September, Italy has a UV Index of 6. This means that the sun can harm your skin in a short time.

To protect yourself from the sun’s harmful ultraviolet rays, you must wear sunscreen. You should also wear a hat for extra protection, as well as loose clothing to avoid getting overheated.

Natural Disasters in September

Italy has had its share of natural disasters before. From volcanoes erupting to earthquakes, Italy is not immune. Many of these natural disasters happened in other months. Although rain is not common in September, an anomaly did hit central Italy in 2022. There was a heavy downpour in the region of Marche, causing flash floods throughout the area.

Visiting Italy in September

There are many things to do in Italy. You can go to Rome and visit the Colosseum, the Trevi Fountain, and other cultural sites. There’s also an art history tour in Florence you can visit. Perhaps you can hit the beach on the Amalfi Coast near Naples or delight yourself with romantic walks along the canals of Venice. Whatever you decide to do, there is something in Italy for everyone.

If September is when you’re visiting Italy, then there are still many things you can do. Some of them are quite different from your typical touristic activities. If wine tasting and grape harvesting are on your bucket list, then September is a perfect time to check it off. Harvest time is usually in September or October of every year. Besides the nature walks you can take in Tuscany, the best part about going to Italy in the ninth month of the year is the possibility of dining at a charming restaurant located in a piazza. 

Things to Eat and Drink in Italy

If there’s one thing Italy is most famous for, it’s food. It has been exported throughout the world. There are Italian restaurants aplenty in any country you go to. It’s a cuisine that is easy to make in nearly any kitchen in the world.

There are so many pasta dishes and pizzas to try while you are in Italy. After all, you will get to try the authentic versions. Perfect for September is ordering truffle pasta with porcini mushrooms. That sounds absolutely delicious! For those healthier people out there, you can always get eggplant parmesan or risotto alla zucca (butternut squash risotto). 

When it comes to drinking, coffee in the morning is key if you want to be an authentic Italian during your trip. For your lunch or dinner, make sure to accompany your scrumptious meal with a glass of red or white wine. Italy is the biggest wine producer in the world, after all.

Fun Facts About Italy

The Trevi Fountain, Italy

There is a myth surrounding the Trevi Fountain. If you throw one coin, you’ll return to Rome. You’ll fall in love with an Italian if you throw two coins. And if you throw three coins, you will marry that Italian.

  • Benito Mussolini was the country’s fascist dictator from 1925 to 1945.
  • Tourists throw about 3,000 euros per day into the Trevi Fountain, which amounts to one million euros (it’s all donated to charity).
  • Even though we don’t know if William Shakespeare ever visited Italy, 13 of his plays are set in the country.
  • Italy has three active volcanoes — Mount Etna, Mount Vesuvius, and Mount Stromboli.
  • About 65 million tourists head to Italy every year, making the country the fifth most visited in the world.
  • Pizza was invented in Naples around the early 1700s.

Conclusion

Italy in September is pleasant and won’t affect your travel plans at all. The summer heat is subsiding, which means you will get sun, but it won’t be that hot. This makes it a perfect time to enjoy the cities of Italy, lay out on the beach or even take a boat ride in Lake Como

Because Italy is one of the top-visited countries in the world, you won’t run out of things to do. You can visit the beautiful natural parks Italy has to offer or the rich cultural sites in every city. Maybe, you’ll even fall in love on a canal bridge in Venice. Your time in Italy will be one to remember!
