Venice is a unique travel destination known as the city of canals. Due to them, the humidity tends to be high throughout the year. During the winter, the night-time drop in temperature causes mists to hover over the canals. It is a wonderful sight appreciated by many photographers!
In the autumn and winter months, Venice weather is susceptible to flooding. This phenomenon, known as Acqua Alta, often occurs in November. Acqua Alta directly links to the tides of the Venetian Lagoon. It lasts only a few hours but can create inconveniences, such as flooding in the lower areas of Venice. When Venice floods, the calle (or the squares) also flood, making it difficult to get around the city on foot. By definition, high water occurs when the level is more than 90 cm or 35.4 inches above sea level. When the tide is higher than usual, the city sirens warn the population 3-4 hours in advance. It is best to plan your Venice itinerary with Acqua Alta in mind.
