Yes, September suits Venice for travelers who want mild afternoons, a sea still warm enough for the Lido and a calendar with the Regata Storica and the International Film Festival.
The month brings rain on six days, and the Doge’s Palace tours that go behind the scenes are by reservation only, so a wet day works best when it’s already planned around a booked visit.

September is mild. Afternoons reach 75°F (24°C), which is comfortable for walking between squares and canals, and nights drop to 59°F (15°C).
Six days bring at least a little rain. Take a light layer for the evening, when the air cools.
August runs hotter, with highs of 83°F (28°C) and eight hours of sun a day. October is cooler, with highs of 65°F (19°C), seven rainy days and sunshine down to five hours a day. September sits between the two, with enough warmth for the Lido and enough daylight (12 hours 37 minutes in mid-month) for a full day of sights.
What to do in Venice in September
Doge’s Palace and the St. Mark’s Square Museums
The Doge’s Palace is at San Marco 1, and visitors enter through the Porta del Frumento on Piazzetta San Marco. The St. Mark’s Square Museums ticket also covers the Museum Correr, the National Archaeological Museum and the Monumental Rooms of the Marciana National Library. The MUVE APP audioguide is included in the ticket price.
Two special visits, the Secret Itinerary and The Doge’s Hidden Treasures, are by reservation only and take a limited number of visitors. The first covers the rooms where Venetian administration worked, and the second leads through the Doge’s private rooms next to the Basilica. Book them before arriving, and keep them for a gray day.
Campanile, Basilica and the Rialto Bridge
The Campanile elevator gives wide, quiet views over the square. The Basilica visit includes the Pala d’Oro and the museum and loggia with the Horses of Saint Mark, and the mosaics are worth the time.
The Rialto Bridge visit is free and takes about 20 minutes on average. It fits easily between the square and a late lunch.
Murano, Burano and Torcello
On Murano, some of the island’s glassworks let you watch glass-blowing. Burano has the Lace Museum, where lace-makers’ techniques can be watched live by reservation. The long ramp from Burano leads to Mazzorbo and its park.
The Museum Pass also covers the Glass Museum on Murano, the Lace Museum on Burano and the Torcello Museum, which helps if you plan to see all three islands.
The Lido and the International Film Festival
The International Film Festival is held in September, and the Lido is where Venice’s beaches, bicycle touring and lagoon discovery are on offer. With the sea at 73°F (23°C), it’s still a place to spend an afternoon.
Plan the Lido for a day without a tight museum schedule, and bring a swimsuit and a bike-friendly outfit.
The Regata Storica
The Regata Storica is held on the first Sunday of September.
Check the exact day in the calendar for your year before you book, since the first Sunday moves from year to year.
Is Venice busy in September?
Other big dates fall elsewhere in the year: Carnival in February and March, the Festa del Redentore on the third Sunday of July.
The reservation-only visits at the Doge’s Palace are the part to book ahead. The same goes for the lace-makers’ demonstration at the Museo del Merletto, which is by reservation.
Guests in accommodation in the municipality pay a tourist tax, collected by the facility manager. It is calculated by applying the municipal rate to the number of nights per person, and it’s due for a maximum of 5 consecutive nights for non-residents. The separate access fee applies only to the historic city, not the minor islands, and it aims to discourage unplanned day visits.
Can you swim in Venice in September?
The sea near Venice averages 73°F (23°C) in September, which is a monthly average. It’s cooler than August, when the sea averages 78°F (26°C), and warmer than October, when it falls to 66°F (19°C).
The Lido of Venice is the place for beaches, bicycle touring and the lagoon. Venice’s own beaches sit there, and the Lido’s pace suits a swim followed by a bike ride.
What to pack for Venice in September
September asks for light clothes by day and a layer by night, plus something for the rain.
- A light sweater or jacket for evenings, when lows reach 59°F (15°C)
- A compact umbrella or rain jacket, for the six rainy days
- A swimsuit and towel for the Lido, where the sea is 73°F (23°C)
- Sunglasses and a hat for sunny days on the islands.
- Your reservation confirmation for the Secret Itinerary or the Hidden Treasures tour
What to know before visiting Venice in September
It also covers Ca’ Rezzonico, the Museum of Palazzo Mocenigo, Carlo Goldoni’s House, Ca’ Pesaro, MUVEC, the Glass Museum, the Lace Museum, the Natural History Museum, the Fortuny Museum and the Torcello Museum.
If you only want three of those, a single ticket covers the Museum of Palazzo Mocenigo, Ca’ Rezzonico and Carlo Goldoni’s House, valid 3 months for one entry per museum. Palazzo Mocenigo is at Santa Croce 1992 and is the Study Centre for the History of Textile, Costume and Perfume.
Is September a good time to visit Venice?
Yes, September is a good month for travelers who want mild weather, museums and a day on the Lido without August’s heat.
If you want film, choose the festival dates. If you want the Regata Storica, arrive for the first Sunday.
