High tides, strong winds, and the full moon can occasionally flood the enchanting historic center of Venice, creating the famous acqua alta.
This natural event happens mostly from autumn to spring, though not every day, and it’s simply part of the city’s unique rhythm.
When the water rises, the lower streets and squares become harder to walk through. Visitors slip on waterproof overshoes or rubber boots, or stroll along elevated walkways made of sturdy iron frames topped with thick wooden planks. As the tide increases, the space beneath some bridges becomes too low for boats and gondolas to pass, so even their routes shift with the water.
A citywide siren announces the arrival of high tide. It may last several hours, but it’s completely safe and offers a fascinating glimpse into daily life in Venice.
The tide rises and falls every six hours, and as soon as the water recedes, the streets open up again and the city returns to normal.
Enjoy Venice in every one of its moods — even when it’s shimmering under a thin layer of water.
