Does Venice smell? Yes, but also no.

The real answer is that it can sometimes smell, but it rarely does. I live near Venice and have been there countless times. I think the canals have smelled twice in all of those times, only in a couple of areas, and only during the hottest months. After the tide started moving, the smell went away.

Truth be told, it’s not the canals that smell. It’s when the dogs urinate on the walls and it doesn’t rain for a while. Some of the out-of-the-way alleys and streets can get a bit ripe due to the number of dogs.

So, there’s your answer but if you’re curious to learn more, read on for the rest of the article. It might not be the most glamorous subject, but it is a question I get a lot, and I thought it best to clear things up because Venice is so worth it.

Key Takeaways

  • Venice’s unique smell is partly due to its sewage system and stagnant water in the canals, which is particularly noticeable near the water and during high sewage strain times, but efforts are ongoing to improve it.

  • The summer heat exacerbates odors in Venice by accelerating the decay of organic material, but responsible tourist behavior regarding waste can help alleviate the problem.

  • Venice’s air quality can be affected by the decay of organic material in canals, posing health risks like respiratory issues; swimming in canals is illegal due to safety concerns, but seafood is generally safe due to strict quality controls.

Does Venice Really Smell That Bad?

So, what actually causes Venice’s smell and is it that bad?

The key contributors to Venice’s distinct smells are its unique sewage system and stagnant water in the canals. However, this doesn’t mean that the entire city stinks. The Venice smell bad perception is more noticeable when walking near the canals, and can be heightened during times of increased strain on the sewage system. In general, Venice smells are a mix of these factors, but not all areas of the city have a strong odor.

Now, let’s delve deeper into these elements to comprehend their contribution to Venice’s distinct smell.

The Role of Canals

The city’s canals of Venice, which heavily influence the overall aroma, serve vital purposes in transportation and waste management. However, shallow canals and slow water flow lead to poor water circulation, which plays a part in the creation of unpleasant odors.

During periods of low boat traffic, the stagnant nature of the canal water can intensify the city’s odor. Additionally, pollution from boats, including the release of fuel and oil into the canal water, contributes to the degradation of water quality, affecting Venice’s aromatic environment.

Tides and Their Impact

In addition to the canals, tides too have a significant impact on managing the city’s odors. Here’s how:

  • High tides help push cleaner Adriatic sea water into the lagoon

  • This dilutes and displaces stagnant water and sewage present in the canals

  • It helps manage and mitigate unpleasant odors over time.

However, during times of low tide or events like acqua alta, the inefficiencies of Venice’s sewage system become more evident, leading to a heightened perception of odor. But, fear not! The smell produced by the canals is typically a temporary concern, thanks to the twice-daily tidal exchange.

The Sewage System: A Unique Challenge

The city’s distinct sewage system is a direct contributor to Venice’s characteristic foul odor. The system discharges wastewater from septic tanks into the canals, which influences the city’s overall scent profile. The liquid waste includes household and industrial wastewater, contributing to the smell when emptied into the canals.

However, Venice is not turning a blind nose to the problem. Efforts to upgrade the sewage system have been undertaken, with modern septic tanks installed in newer buildings, and plans to overhaul the entire city’s system. But until these efforts fully bear fruit, the city remains’ aroma, with its distinct city smells, carries a hint of its sewage challenge.

Gatoli and Septic Tanks

Historically, Venice employed a brick sewer system, known as ‘gatoli’, for waste disposal. These ‘gatoli’ channeled sewage directly into the city’s canals, contributing to the odors historically associated with Venice.

However, Venice’s sewage system has come a long way since the days of ‘gatoli’. Now, septic tanks are mandatory in buildings across the city, which has helped reduce the intensity of the city’s smell.

Waste Management Efforts

Acknowledging the need for enhancement, Venice has initiated significant efforts to minimize the presence of garbage on its streets. In 2016, the city introduced a new waste collection system that includes door-to-door garbage pickup and boats equipped with trash compactors. This system now services around 99% of Venice’s historic center.

These waste collection boats handle various types of waste, including organic waste, and have staff to ensure proper sorting. Venice encourages tourists to engage in responsible waste disposal, reducing the overall waste and helping maintain the city’s charm.

Summer Season and Its Effects

Despite being a year-round destination, Venice faces distinct challenges during the summer season. The summer heat, which can reach up to 95 F (35 C) or above, accelerates the decay of organic material in the water, resulting in the emission of foul-smelling gases.

Combined with the influx of tourists, the summer months can exacerbate the city’s unpleasant smell. Some factors that contribute to the occasional bad smell during the summer season include:

  • More waste

  • Faster decay

  • Potential algae buildups

  • Poor water circulation in the canals

Algae Blooms and Hot Weather

Venice experiences a humid subtropical climate with hot and humid summers, which provides an environment conducive for algae growth. Algae buildup is one of the most common scents in Venice during periods of hot weather and little rain, resulting in an algae smell.

Nevertheless, the intensity of the smell in Venice fluctuates with weather conditions, being especially noticeable in specific areas during times of the year when the summer heat accelerates decay processes.

Tourist Behavior and Waste Production

Tourists in Venice play a significant role in waste production, generating more than twice the average per capita waste compared to residents. This increase in waste production, along with improper disposal practices, can exacerbate the odor problem in Venice during the busy summer season.

However, by disposing of waste correctly and refraining from littering, visitors to Venice can play a crucial role in preventing the intensification of unpleasant smells. So, next time you visit, remember: your actions matter!

Navigating Venice’s Scents: Tips for Visitors

Having demystified Venice’s unique aroma, let’s discuss how to ensure your visit to the city is as enjoyable as possible. Did you know that the time of your visit can significantly impact your scent experience? Visiting during spring and fall may offer a more comfortable experience as the odors are typically less pronounced compared to peak summer months.

In addition to choosing the right time to visit, consider staying in an area closer to the sea for fresher air, seek out well-ventilated areas for breaks, and use a scarf or mask if necessary. Remember, your trip to Venice is about more than just the smell – it’s about experiencing the beauty, history, and culture of this unique city.

Best Times to Visit

Choosing the right time to visit is one of the best ways to enjoy Venice without the stronger odors. August in Venice is marked by heat, humidity, and mosquitoes, making it a less desirable month for visitors.

September, on the other hand, offers more pleasant weather and typically sees fewer tourists, contributing to lesser canal odors. October is favored as an ideal time to visit Venice, as the cooler weather reduces the intensity of any unpleasant smells, offering a more agreeable experience.

So, if you’re planning a trip to Venice, consider timing your visit to make the most of your experience.

Responsible Tourism Practices

While timing is indeed important, your behavior as a visitor also has a significant impact on preserving Venice’s environment. By choosing sustainable accommodation, supporting local businesses, and reducing plastic waste, you can contribute to the city’s preservation.

Follow the #EnjoyRespectVenezia campaign guidelines to aid in preserving Venice’s environmental and artistic heritage. Small actions can result in big changes, so remember to respect Venice’s social etiquette and explore less-frequented neighborhoods and the broader Veneto region for a more genuine experience.

Health and Safety Concerns

Although Venice’s unique aroma is intriguing, it’s equally important to consider its implications on health and safety. The decay of organic material in Venice’s canals adversely affects air quality, releasing foul-smelling gases with potential health effects. Some of the potential health effects include:

  • Respiratory issues

  • Allergic reactions

  • Eye and throat irritation

  • Headaches

It is important to be aware of these potential health effects when visiting Venice and take necessary precautions.

However, Venice does not ignore these concerns. Waste management initiatives in Venice aim to reduce garbage sent to incineration plants, which is expected to decrease CO2 emissions affecting air quality. Moreover, consuming seafood from reputable restaurants in Venice is generally safe, as it is sourced from the cleaner waters of the Adriatic Sea.

Swimming Safety

The allure of cooling off in Venice’s iconic canals, including the Grand Canal, might be strong, especially on sweltering summer days. However, swimming in Venice’s canals is discouraged primarily because of the water’s poor quality. In fact, it’s top of the list for rules in Venice to abide by.

Not only is the water quality poor, but swimming in the canals is also prohibited due to dangers such as water traffic from gondolas and motorboats, as well as the unsanitary water conditions. Violating the ban on swimming can result in legal repercussions, including a €350 fine and potentially being removed from the city.

Seafood Safety

For seafood enthusiasts, Venice is a veritable delight. Venice is known for its fresh seafood, and you might be wondering if it’s safe to eat. Rest assured, controls on seafood quality in Venice are stringent, reducing the risk of consuming contaminated seafood from the lagoon.

Venice takes proactive measures to ensure seafood safety, such as monitoring the presence of toxins from Dinophysis spp. through high-resolution mass spectrometry. Moreover, the harvesting of clams is forbidden in areas of the western lagoon near industrial plants to prevent potential risks associated with contamination.


We’ve come a long way from the common misconception of Venice as a stinky city. As we’ve discovered, Venice’s unique scent profile is a complex mix of its unique sewage system, stagnant canal water, and the influence of tides.

But remember, the occasional whiffs of unpleasant smells are part of Venice’s charm, telling the tale of its rich history and unique environment. So, the next time you visit Venice, embrace its unique smells, respect its heritage, and immerse yourself in the sensory experience of this beautiful city.
