If you’re planning a trip to Venice and you’ve heard about flooding in the city, you might be wondering: Does Venice experience flooding? Should I be worried? Will it ruin my trip?
The short answer is: yes, Venice does experience flooding, especially in the autumn and winter months. This phenomenon is known as “acqua alta” — or “high water” — and it’s part of the city’s unique relationship with the lagoon. But the long answer is much more reassuring: acqua alta is manageable, often short-lived, and rarely a reason to cancel or avoid visiting Venice.
In fact, knowing how it works — and having local support if it happens during your trip — can turn it into an opportunity to experience Venice like a true insider.
Let’s explore what acqua alta really is, how it affects daily life, and how Tour Leader Venice can help you find the best solutions, whether you’re joining a Venice walking tour, a Venice boat tour, or just trying to get to your hotel.
What Is Acqua Alta?
Acqua alta literally means “high water” in Italian, and it refers to temporary flooding events that occur when the tide in the Venetian Lagoon rises above normal levels. These events are influenced by a mix of natural factors:
-
The lunar cycle
-
Wind direction (particularly the scirocco from the south)
-
Atmospheric pressure
-
Heavy rainfall
-
Seasonal water levels in the Adriatic Sea
When all these align — typically in autumn and winter — the sea pushes into the lagoon and water levels rise, sometimes spilling into the lowest parts of the city.
When Does Flooding Happen in Venice?
Flooding in Venice usually occurs from October to January, with November being the most common month for acqua alta. But not every tide is extreme, and only the lowest areas, such as Piazza San Marco, get affected most often.
Fun fact: Venice has a complex tide forecasting system that locals check daily, just like the weather. If the forecast predicts high water above a certain threshold, warning sirens sound throughout the city — and the city reacts quickly.
How High Does the Water Get?
Water levels in Venice are measured relative to the average sea level at Punta della Salute. Here’s a general idea of what different acqua alta levels mean:
-
Up to 80 cm: Normal high tide, no major problems.
-
80–100 cm: Minor flooding in low-lying areas.
-
100–110 cm: Some areas flood, including Piazza San Marco.
-
110–130 cm: More widespread flooding, but still manageable.
-
Above 130 cm: Serious flooding, usually rare and short-lived.
Keep in mind: a 100 cm tide doesn’t mean the whole city is underwater — it just means water may cover some streets or squares in the lowest points of Venice.
How Does the City Handle It?
Venetians have been living with acqua alta for centuries — and they’ve developed ways to adapt quickly. Here’s how Venice responds:
1. Raised Walkways (Passerelle)
When acqua alta is forecasted, the city quickly installs temporary raised walkways across affected areas. These metal and wooden platforms let people walk above the water. You’ll often see them in key areas like St. Mark’s Square, Rialto, and popular tourist routes.
2. Tide Alerts
You’ll hear siren alerts if high tide is expected above 110 cm. These sirens follow a pattern of tones indicating the expected height — locals recognize the meaning immediately.
If you have a smartphone, you can download apps or use websites like hi.venezia.it for real-time updates.
3. Boot Sales
During acqua alta, shops sell waterproof boot covers and plastic overboots. You can also rent them at some hotels or even borrow them from locals — Venetians are used to helping!
What Happens During Acqua Alta for Tourists?
If you’re visiting Venice during a high tide, your experience will change slightly — but not necessarily in a bad way. In fact, it can be quite charming if you’re prepared. Here’s what to expect:
-
Tourist attractions stay open: Most museums, churches, and landmarks (including the Doge’s Palace and St. Mark’s Basilica) remain open. Tours may shift start points, but they go on.
-
Raised walkways make movement possible: You won’t be wading through waist-deep water — you’ll be walking on elevated paths.
-
Photos become magical: Reflections of the basilica in the flooded square make for unforgettable pictures.
-
Boats keep running: Water taxis and Venice boat tours continue operating unless conditions are extreme.
What If I Have a Tour Booked During Acqua Alta?
At Tour Leader Venice, we monitor tide levels daily. If flooding is forecasted, we:

What About Transportation During High Water?
Getting around during high water can be confusing, but you won’t be stranded:
Vaporetto (Water Buses)
These generally keep running, though stops in flood-prone areas (like San Marco) may be temporarily suspended.
Water Taxis
Most operate normally, but boarding and docking might shift to higher platforms or safer piers.
Walking
With the raised walkways and helpful signs, you’ll be able to reach most places — slowly, but surely. And with Tour Leader Venice, we’ll guide you personally if you’re unsure.
