September is when Milan wakes back up. The city effectively shuts down for August, with whole neighborhoods going quiet as Milanese families head to Sardinia, Liguria, or the Dolomites. By the first week of September, the lights come back on. Restaurants along Naviglio Grande that pulled their shutters down on August 1 start serving again. The energy in Brera shifts from sleepy to purposeful. And then, typically around the third week, Settimana della Moda takes over and the entire city tilts toward fashion.
The weather tends to cooperate more than you might expect. Highs average 24.5°C (76°F), which feels like the comfortable tail end of summer without the sticky 30°C heat of July and August. Mornings in Parco Sempione carry a crispness that was not there 4 weeks ago. That said, September does see its share of rain, averaging around 82mm across roughly 8 days. The pattern tends to be sharp afternoon downpours rather than all-day gray, so plan outdoor time for the mornings. By evening, temperatures drop toward 15.9°C (61°F), and you will want a light jacket for aperitivo on the canal.
Think of it as two Septembers. The first half still carries a late-summer calm, with reasonable hotel rates and easy restaurant reservations in neighborhoods like Porta Romana and Isola. The second half belongs to the fashion world. Hotel prices near the Quadrilatero della Moda can double during Fashion Week, and the sidewalk tables at Giacomo Caffè on Via della Spiga fill with editors and buyers. If you are not attending shows, early September is the better bet for value and elbow room.
Why visit in September
- Temperatures drop from the 30°C summer peak to a comfortable 24.5°C (76°F) average, making walking the city pleasant again after July and August's heat
- The cultural season restarts. Teatro alla Scala begins its autumn programme, galleries in Brera reopen after August closures, and Fondazione Prada typically launches new exhibitions
- Settimana della Moda (Milan Fashion Week) in the third or fourth week brings a charged, photogenic atmosphere to the city center, even if you are not attending shows
- MITO SettembreMusica stages free and ticketed concerts in churches, courtyards, and concert halls across Milan and Turin throughout the month
- The first porcini mushrooms of the season arrive from the pre-Alpine forests north of Bergamo, and restaurants across the city put risotto ai funghi porcini on their menus
Worth knowing
- September averages around 82mm of rainfall across 8 days, not extreme by Milan standards but enough that you should expect at least a couple of sudden, heavy afternoon downpours
- Hotel prices rise noticeably during Fashion Week, with rates near Via MonteNapoleone and Porta Nuova reaching 2 to 3 times their normal level
- The Gran Premio d'Italia at Monza (typically the first or second Sunday) floods Milan's hotels and transit with F1 fans, adding to the Fashion Week price pressure later in the month
- Po Valley humidity sits at 73% on average, which can make the 24°C afternoons feel warmer and stickier than the number suggests
Best for
Think twice if
September sits at the seam between summer and autumn in Milan. Early in the month you might still get warm, bright afternoons that feel like late August. By the final week, the light changes and the air carries a coolness after sunset that signals autumn. Rain is a factor but not a dominant one. At around 82mm across 8 days, September is moderate compared to the wetter months of October and November, when Milan typically sees 100mm or more. The pattern tends to be clear mornings followed by heavy afternoon showers that blow through in 30 to 45 minutes. Humidity hovers around 73%, which makes the midday hours feel warmer than the thermometer reads. Fog, Milan's signature weather, has not yet settled in. That is more of an October and November phenomenon.
Seasonal caution
- Afternoon thunderstorms in the Po Valley can arrive fast and drop heavy rain in a short window. Lightning is common during September storms, so move indoors if you hear thunder while walking in Parco Sempione or along the Navigli canals

Headline events
Settimana della Moda di Milano (Milan Fashion Week)
Third or fourth week of September (typically runs Tuesday to Monday, roughly September 17-23)
One of the Big Four fashion weeks alongside Paris, New York, and London. Major Italian and international houses show their spring/summer collections in venues across the city, from the Palazzo Reale to converted industrial spaces in Tortona. The surrounding events, parties, and pop-ups transform Brera, Porta Nuova, and the Quadrilatero della Moda for roughly 6 days.
Best things to do in September
Attend a MITO SettembreMusica concert
cultureThis month-long music festival spans Milan and Turin with a programme of over 100 concerts. Performances happen in churches, palazzi courtyards, the Conservatorio di Milano, and smaller venues across both cities. The repertoire ranges from baroque chamber music to contemporary composition, with several free performances each week.
MITO SettembreMusica runs exclusively in September, with concerts scheduled nearly every evening throughout the month.Booking tipFree concerts fill up fast. Arrive 30 to 45 minutes early for unreserved seating at the more popular church venues like San Marco and Santa Maria dei Miracoli.
Walk the Navigli canals in the early-autumn light
sightseeingThe Naviglio Grande and Naviglio Pavese are lined with bars, vintage shops, and small galleries. September's lower angle of afternoon sunlight throws long shadows across the water and the pastel-colored buildings along the Alzaia Naviglio Grande. The stretch between the Darsena and the Vicolo dei Lavandai is roughly 2 km.
The 24°C average makes walking comfortable again after summer's 30°C heat, and the canal-side restaurants have reopened after August closures.Visit the Pinacoteca di Brera
cultureMilan's most important art gallery reopens fully after the slower August period. The 38 rooms house Mantegna's Dead Christ, Raphael's Marriage of the Virgin, and Caravaggio's Supper at Emmaus. The Palazzo di Brera also holds the Orto Botanico, a small botanical garden tucked behind the gallery that is particularly pleasant in September's warmth.
The gallery's autumn exhibition programme typically launches in September, and the summer crowds thin out noticeably in the first 2 weeks.Booking tipBook timed entry online to skip the ticket queue, which can reach 20 to 30 minutes on weekends.
Day trip to Monza for the Italian Grand Prix
sportThe Autodromo Nazionale di Monza sits inside the Parco di Monza, roughly 20 km northeast of Milan's city center. The circuit has hosted F1 since the inaugural 1950 season, making it one of the oldest venues on the calendar. Race weekend turns the park and the town of Monza into a sea of red Ferrari flags and tifosi chanting.
The Gran Premio d'Italia is traditionally held on the first or second Sunday of September. The 2025 race was on September 7.Booking tipGeneral admission tickets sell out months ahead. The S7 suburban train from Milano Centrale to Monza takes about 15 minutes, but expect heavy crowding on race day.
Explore the Fondazione Prada
cultureRem Koolhaas's complex in Largo Isarco includes a converted 1910 gin distillery, a gold-leaf-clad haunted house, and a permanent installation by Robert Gober. The Fondazione typically opens its autumn exhibitions in September, and Bar Luce, designed by Wes Anderson, sits inside the complex.
New autumn exhibitions tend to open in September, and the outdoor spaces of the complex are comfortable to explore at 24°C.Booking tipWeekday mornings see the lightest foot traffic. The complex is large enough that even moderate weekend crowds spread out across its buildings.
Aperitivo crawl through Isola and Porta Nuova
food_and_drinkThe Isola neighborhood, north of Porta Garibaldi station, has become one of Milan's liveliest aperitivo zones. Via Borsieri and Via Pastrengo are lined with small bars that serve drinks with generous plates of stuzzichini. Porta Nuova's towers and the Biblioteca degli Alberi park sit within a 10-minute walk.
Bars reopen their outdoor terraces after August closures, and the 16°C evenings are warm enough to sit outside without needing a heavy coat.Booking tipMost aperitivo spots do not take reservations for the bar area. Arrive by 18:30 to get an outdoor table on Via Borsieri.
Browse the antiques market on Naviglio Grande
shoppingThe Mercatone dell'Antiquariato runs along the Alzaia Naviglio Grande on the last Sunday of each month. Roughly 400 vendors set up stalls selling vintage furniture, old prints, ceramics, jewelry, and mid-century modern pieces. The market stretches about 2 km from the Darsena toward the western edge of the canal.
The September edition tends to draw strong vendor turnout after the August break, and the weather is reliably comfortable for a morning of outdoor browsing.Booking tipArrive before 09:00 if you want first pick at the better stalls. The market runs until about 18:00.
Visit Leonardo's Last Supper at Santa Maria delle Grazie
cultureLeonardo da Vinci's 1495-1498 mural in the refectory of Santa Maria delle Grazie remains one of Milan's most visited works. Entry is limited to groups of roughly 25, with each group given 15 minutes in the refectory. The fresco measures approximately 4.6 by 8.8 meters on the north wall.
September bookings are slightly easier to secure than peak summer months, though you still need to reserve weeks in advance. The cultural season restart brings extended opening hours on some evenings.Booking tipTickets open about 2 months in advance on the official site. Check for cancellations if your preferred date is sold out, as slots tend to reappear in the final week before a visit date.
What to eat in September
In season: fruit
Fichi (late-season figs)
The second crop of figs (fioroni come first in June) reaches its peak sweetness in September. You will find them at market stalls across the city, often paired with prosciutto crudo or served with soft cheese like stracchino. The late-season fruit tends to be smaller and more concentrated in flavor than the June harvest.
Uva fragola (strawberry grape)
These small, intensely aromatic grapes appear briefly at outdoor markets in September. The name comes from their strawberry-like sweetness. They grow across Lombardy and the Veneto, and the season typically lasts only 3 to 4 weeks.
On menus now
Risotto ai funghi porcini
The signature early-autumn primo in Milan. Fresh porcini sliced thick and stirred through Carnaroli rice with butter and Parmigiano. Every trattoria in the city puts some version on its menu the moment the mushrooms arrive, usually by the second week of September.
In markets
Funghi porcini
September marks the start of porcini season in Lombardy. The mushrooms arrive from forests in the valleys north of Bergamo and Brescia, and they show up at markets like Mercato Comunale on Via Fauché within days of foraging. The scent is unmistakable, earthy and faintly sweet.
Zucca (winter squash)
Mantuan pumpkin starts arriving at Milanese markets toward the end of September. It shows up in tortelli di zucca, the filled pasta from Mantova that pairs sweet squash with crushed amaretti and mostarda. Worth noting that the dish tends to appear on menus in Navigli and Brera before it becomes a full autumn staple in October.
Regular events in September
Gran Premio d'Italia (Italian Grand Prix)
Formula 1 race at the Autodromo Nazionale di Monza, 20 km from Milan. One of the fastest circuits on the calendar, with an average lap speed above 250 km/h. The tifosi atmosphere in the grandstands and the post-race track invasion are distinctive to Monza.
First or second Sunday of SeptemberMercatone dell'Antiquariato del Naviglio GrandeFree
Monthly antiques and vintage market along the Alzaia Naviglio Grande, with roughly 400 vendors stretching 2 km along the canal. Furniture, prints, ceramics, jewelry, glassware.
Last Sunday of SeptemberMITO SettembreMusica
Month-long classical and contemporary music festival shared between Milan and Turin, with over 100 concerts in churches, courtyards, conservatories, and concert halls. A mix of free and ticketed performances.
Throughout SeptemberLa Scala autumn season preview
Teatro alla Scala typically begins its autumn concert and ballet programme in September, ahead of the main opera season that opens on December 7 (Sant'Ambrogio). Early-season performances often include symphonic concerts by the Filarmonica della Scala.
Mid to late SeptemberBest places this September
Duomo di Milano
landmarkMilan's Gothic cathedral took nearly 6 centuries to complete (1386-1965). The rooftop terraces offer views across the Po Valley to the Alps on clear September mornings, and the 135 spires are best seen in the slanting autumn light. The Madonnina statue at the top stands 108.5 meters above the piazza.
Centro StoricoNaviglio Grande
neighborhoodThe oldest of Milan's navigli, completed in 1272 to transport marble from Lake Maggiore for the Duomo's construction. The canal runs 50 km from the Ticino river to the Darsena basin. In September the waterside restaurants and bars are open again after their August break, and the evening passeggiata along the Alzaia picks up.
NavigliQuadrilatero della Moda
shoppingThe rectangle formed by Via MonteNapoleone, Via della Spiga, Via Manzoni, and Corso Venezia. During Fashion Week, this is the epicenter. Even outside the shows, the window displays at Prada, Versace, and Armani's flagship stores change for the new season. The 18th-century palazzo facades along Via della Spiga are worth the walk regardless of fashion interest.
Centro StoricoParco Sempione
parkThe 47-hectare park behind the Castello Sforzesco. In September, the plane trees start to turn, and the lawns fill up again after the empty August weeks. The Arco della Pace at the northwest end frames a clear view back to the Castello. The park holds the Triennale design museum and the Torre Branca, a 108-meter steel observation tower built in 1933.
SempioneFondazione Prada
museumRem Koolhaas's 2015 conversion of a 1910 gin distillery in Largo Isarco. The complex spans 19,000 square meters across 7 buildings, including the gold-leaf Haunted House and a permanent Robert Gober installation. Bar Luce, designed by Wes Anderson to resemble a classic Milanese cafe, is inside.
Porta RomanaPinacoteca di Brera
museumMilan's premier art collection, housed in the 17th-century Palazzo di Brera. 38 rooms hold works by Mantegna, Raphael, Caravaggio, Bellini, and Hayez. The Orto Botanico behind the palazzo is a 5,000-square-meter garden open to visitors.
BreraCimitero Monumentale
landmarkMilan's monumental cemetery, opened in 1866, functions as an open-air sculpture museum. The Famedio entrance hall houses the tombs of Alessandro Manzoni and other notable Milanese figures. The cemetery covers 250,000 square meters and contains works by Medardo Rosso and Adolfo Wildt among hundreds of private family monuments.
Porta VoltaBiblioteca degli Alberi
parkThe 9-hectare park in the Porta Nuova district, designed by Petra Blaisse, opened in 2018. It sits beneath the Bosco Verticale towers and the UniCredit Tower (231 meters, Milan's tallest building). In September, the park hosts outdoor yoga sessions, film screenings, and small concerts as part of the BAM cultural programme.

Insider tips
The rooftop terraces of the Duomo are best visited in the first hour after opening, around 09:00. By midday, the queue for the stairs can stretch 30 minutes or more, and the elevator line is typically longer still. On clear September mornings, you can see the Monte Rosa massif from the top.
Milan's aperitivo tradition is more than a drink. Many bars in Navigli and Isola serve a generous spread of small dishes with each drink order, enough that you might not need a full dinner afterward. The ritual typically starts around 18:00 and runs to 21:00.
The Quadrilatero della Moda becomes a street-style photography zone during Fashion Week. Even if you have no connection to the shows, walking Via della Spiga and Via MonteNapoleone during the third week of September feels like watching a live fashion editorial.
The Darsena, the old port basin where the Naviglio Grande meets the Naviglio Pavese, was restored in 2015 for Expo Milan. The area around it has a small outdoor market on weekend mornings that sells local cheese, salumi, and bread from Lombardy producers.
If you are visiting the Last Supper, the Basilica di San Maurizio al Monastero Maggiore is a 5-minute walk away on Corso Magenta. It is sometimes called Milan's Sistine Chapel for its 16th-century frescoed interior, and it sees a fraction of the tourist traffic.
ATM (Azienda Trasporti Milanesi) runs Milan's metro, trams, and buses. A contactless bank card works directly on the turnstiles and validators, no need to buy a separate ticket. The system charges per ride.
Avoid these mistakes
- Assuming all of September is Fashion Week. The shows run for roughly 6 days in the second half of the month. The first 2 weeks of September are calmer, less expensive, and easier to navigate.
- Booking a hotel near Via MonteNapoleone during Fashion Week without checking the dates. Rates in that area can reach 2 to 3 times their normal level during show week, while neighborhoods like Città Studi and Porta Romana stay closer to baseline.
- Skipping reservations at popular restaurants in the first week of September. The city reopens from August holidays all at once, and locals who have been away for a month flood their favorite spots. Trattorie in Brera and the Navigli fill up fast.
- Wearing open sandals or smooth-soled shoes on a rainy day. Milan's stone sidewalks and cobblestone streets in the Navigli and Brera districts get genuinely slippery when wet. Closed-toe shoes with rubber soles save you the worry.
- Planning a day trip to Lake Como on a Monday. Several villas, including Villa del Balbianello and Villa Carlotta, close on Mondays. The train from Milano Centrale to Varenna takes about an hour, so it is an easy trip, but check opening days first.
Practical tips for September
Milan's metro (M1 through M5) covers the main tourist areas efficiently. Line M1 (red) connects the Duomo to Cadorna (for the Last Supper area) and beyond. Line M2 (green) reaches Porta Genova for the Navigli. Most central attractions sit within a 20-minute walk of each other, and September's 24°C average makes walking the easiest way to navigate. For the Monza Grand Prix, take the S7 suburban train from Milano Centrale, roughly 15 minutes, but expect heavy crowds on race day. Book Last Supper tickets at least 6 to 8 weeks ahead. September is a transition month for restaurant hours. Some places that kept reduced August schedules may not return to full service until the second week. If a restaurant's Google listing says it is open but the door is locked, check for a handwritten sign noting the riapertura date. Tipping is not expected in Milan, though rounding up or leaving a few coins is appreciated at trattorias. A coperto (cover charge) of a few euros per person appears on most restaurant bills and is standard, not a scam.
FAQ
Is September a good time to visit Milan?
September is one of the better months for Milan. The 24.5°C average high is comfortable for walking, the cultural season restarts after the August shutdown, and the city has a purposeful energy that feels different from the tourist-heavy summer months. The main tradeoffs are Fashion Week pricing in the second half and the occasional afternoon thunderstorm. If you time it for the first 2 weeks, you get pleasant weather, reopened restaurants, and moderate hotel rates.
How much does Fashion Week affect hotel prices in Milan?
Significantly, but it depends on location. Hotels near the Quadrilatero della Moda and Porta Nuova can see rates reach 2 to 3 times their normal level during the roughly 6-day show period, typically in the third or fourth week of September. Neighborhoods further from the center, like Città Studi, Porta Romana, and Lambrate, see smaller increases. Booking early September avoids the spike entirely.
Does it rain a lot in Milan in September?
September averages about 82mm of rain across roughly 8 days. That is moderate by Milan standards, less than October or November. The pattern tends to be clear mornings with sharp afternoon downpours lasting 30 to 45 minutes. Mornings are usually the best window for outdoor sightseeing, and a compact rain jacket handles the storms better than an umbrella.
Can I visit Lake Como as a day trip from Milan in September?
Easily. Trains from Milano Centrale reach Varenna in about an hour, and Bellagio and Menaggio are accessible by ferry from there. September weather at Lake Como tends to be warm and clear, around 22 to 24°C, with thinner crowds than July and August. Check villa opening days before you go. Villa del Balbianello and Villa Carlotta close on Mondays.
What food is in season in Milan in September?
Porcini mushrooms are the headliner. They arrive from the pre-Alpine forests north of Bergamo in early September and appear on nearly every trattoria menu as risotto ai funghi porcini within days. Late-season figs hit their sweetest point. Mantuan pumpkin starts showing up toward month's end, bringing tortelli di zucca with it. Uva fragola, small strawberry-scented grapes, have a brief 3 to 4 week window at outdoor markets.
Do I need to book Last Supper tickets in advance for September?
Yes. Advance booking is necessary, typically 6 to 8 weeks before your visit. Each time slot admits roughly 25 people for a 15-minute viewing. September is somewhat easier to book than peak summer, but popular time slots still sell out weeks ahead. Check for cancellation openings in the final days before your preferred date, as returned tickets do appear.
