Italy in September: Weather, Harvest, Events and Where to Go (2027)

Italy in September is summer with the edges softened: the sea is still warm, the vineyards are busy with the harvest, and the August crowds thin out week by week. However, the month has two faces, because the first half still feels like high season. So this guide splits September 2027 into early and late, with climate normals, the first-weekend events and where to go.

Italy in September 2027 at a glance

First, here are the dates that shape the month. Some are fixed by tradition, while others come from organizers who had already published them.

In short, the first week is crowded and eventful, and the last two weeks are calmer and cheaper. If you are still choosing a month, our guide to the best time to visit Italy compares the whole year. Also, for the wider season, see Italy in fall.

Italy in September: weather by region

September is warm almost everywhere, although nights start to cool. The figures below are 1991–2020 normals for four airport stations. They come from NOAA’s WMO climate normals and Italian weather-service data (checked September 2026). However, they are rounded averages, not a forecast.

Early versus late September

The averages hide a slide through the month. In fact, the first days often feel like August, while the last week brings fresher mornings. Rain, meanwhile, tends to arrive as short, heavy storms rather than gray days. So a light rain jacket matters more than an umbrella.

The sea and the mountains

At sea level, the water stays warm after the summer, so swimming is easy in the south and on the islands all month. By contrast, the Alps turn crisp. Some high huts and lifts close during the month, so check each one before you plan a mountain day.

Early or late September in Italy?

This is the key decision for a trip to Italy in September. Both halves work, but they suit different travelers.

As a rule, pick early September for the coast and the big events. Then pick late September for vineyards, hill towns and calmer museums. Rates change daily, however, so compare prices for your exact dates rather than trusting averages.

Harvest season: the vendemmia in September

September is the heart of the vendemmia, the grape harvest. Timing, however, moves with the weather each year and with the grape. For example, the Chianti Classico consortium describes its 2023 Sangiovese harvest as starting around September 20 and ending in early October (checked September 2026).

As a result, early grapes and whites come in first, while Tuscan reds follow later in the month. Late reds such as Nebbiolo in Piedmont often wait until October. Keep in mind that small wineries are busy in the cellar during picking, so book tastings ahead.

Wine events in September

In Tuscany, the official Expo Chianti Classico site lists its 54th edition in Greve in Chianti from September 10 to 13, 2026 (checked September 2026). The 2027 dates were not out yet, so check before you plan. Meanwhile, a Chianti wine tour from Florence is the easiest way into harvest country. Our guides to Chianti wine tours and Italian wine regions help you choose an area.

No truffle hunting in Piedmont yet

One thing September does not offer is the white truffle. The Piedmont Region’s truffle calendar bans harvesting of all species from September 1 to 30, and the white truffle opens on October 1 (checked September 2026). So if truffles are the goal, our guide to Italy in October is the better starting point.

Events in Italy in September 2027

Only a few September events had official 2027 dates when checked. So here they are first, followed by the recurring ones. Also, our events in Italy hub adds more as organizers publish them.

Italian Grand Prix at Monza

According to the Autodromo Nazionale Monza, the 2027 Italian Grand Prix runs from September 3 to 5, with a Sprint race (checked September 2026). As a result, hotels in Milan and around Monza book up early that weekend.

Macchina di Santa Rosa in Viterbo

Every year on the evening of September 3, Viterbo carries a tower about 30 meters tall through its old town. The Italian National Commission for UNESCO notes that more than one hundred men carry it on their shoulders, and that UNESCO listed the event in 2013 (checked September 2026). In 2027, September 3 falls on a Friday. For the area, see our Tuscia travel guide.

Regata Storica in Venice

The Regata Storica is traditionally held on the first Sunday of September. First comes a parade of historic boats with crews in period costume, then the races on the Grand Canal. The official Regata Storica site listed the 2026 edition for Sunday, September 6 (checked September 2026). The 2027 date was not published, so check, although the pattern points to September 5.

Venice Film Festival

The festival takes over the Lido in late summer. According to the Biennale, the 2026 edition ran from September 2 to 12 (checked September 2026). The 2027 dates were not yet announced. Meanwhile, the Architecture Biennale runs until November 21, 2027 (checked September 2026). So Venice stays busy all month, and our guide to 3 days in Venice helps you pace the visit.

Jousts and palios

• Giostra del Saracino, Arezzo. The City of Arezzo says the September joust takes place on the first Sunday of the month (checked September 2026). So in 2027, that should be September 5.
• Palio di Asti. The City of Asti listed the 2026 trials and race for September 5 and 6 (checked September 2026). However, the 2027 date was not published.
• San Gennaro, Naples. September 19 is the feast of the city’s patron saint, and in 2027 it falls on a Sunday. Expect crowds around the cathedral.

Museums and free days in September 2027

Two free-entry rules fall inside the month. First, the Domenica al museo program opens state museums for free on the first Sunday of each month (checked September 2026). So in September 2027, that is September 5, the same day as the jousts. Booking applies where required.

Second, the Vatican Museums open free on the last Sunday of the month, in the morning only (checked September 2026). So September 26, 2027 should qualify. Free days bring long lines, however, so a timed weekday ticket is often the better choice. Our guides to Vatican Museums tickets and free museum days in Italy explain the options.

Where to go in Italy in September

September suits almost every region. Still, a few places are at their best now, in the gap between summer crowds and autumn rain.

The Amalfi Coast and Capri

Boats still run their full season. For example, NLG lists its Positano–Capri line from April 1 to November 3, 2026 (checked September 2026). Our guide to Amalfi Coast ferries explains the routes. Then, on the water, compare an Amalfi Coast boat tour or a Capri boat tour with the Blue Grotto.

The Cinque Terre

Late September is a good window for the coastal trails, since the heat eases. In addition, Trenitalia runs the Cinque Terre Express until November 1, 2026 (checked September 2026). Check trail status in our guide to Cinque Terre hiking first. Also, on a calm day, a Cinque Terre boat tour shows the villages from the sea.

Tuscany and the wine country

Late September is harvest time in Chianti and Montalcino. So pair a city stay in Florence with a Montalcino Brunello wine tour. Farther north, similarly, the Veneto hills suit a Prosecco hills wine tour from Venice.

Sicily and Puglia

Finally, the far south keeps its summer warmth, and Palermo’s nights stay near 69 °F. For example, Sicily suits an Etna wine tour from Taormina, since the volcano’s vineyards harvest in the fall. In Puglia, similarly, consider an Alberobello and Matera day trip from Bari.

What to pack for Italy in September

Pack, then, for summer days and cooler evenings:

• Light, breathable clothes, plus a sweater for evenings in the north.
• Also, a thin rain jacket for short storms.
• Comfortable walking shoes for cobblestones and vineyard paths.
• Sunscreen, sunglasses and a hat, since the sun is still strong.
• A scarf or top that covers shoulders for churches and the Vatican.
• Finally, a swimsuit, because the sea stays warm all month.
