The phenomenon of high tides is such a common experience that the Venetians have come to accept them without any big fuss. It has been possible to see gondolas on the Square or even beneath the arcades.
If you are caught by high waters, under no circumstances be tempted, even if you see others doing so, to remove your shoes and walk barefoot. As soon as possible wash your feet and shoes carefully under plenty of fresh running water because the floodwater is saline.
Everyone knows that Venice is drowing. If few years ago high water was a dangre only few times a year - now it changes for worse. Sometimes in the evening you can see water on the street that goes along San Marco place.
Venice is sinking!!!!It is said it sinks at a rate of about 10 inches a century! Be sure to visit!!! I doubt in our lifetime, it will be gone..but they do experience problems with flooding. In the winter ,they experience'acqua alta' or the 'high water' and the streets get flooded. When this happens, elevated wooden planks are erected to make sidewalks at the more frequented areas.
During full moon and high tide, water bubbles up through Venice sewers flooding areas including St. Marks Square. While I watched the beautiful full moon and listened to outdoor concerts, water crept silently closer to my feet.
Don't make the same mistake I did, that is, waiting until the last minute to purchase gifts. I went back to town the next day, hoping to go back to some of the shops I had seen, and explore the rest of the city when it flooded! Granted, it was the rainy season, and it was a full moon, but I was not prepared for so much water! Fortunately, we found a store that was selling garbage bags to be used as boots. It worked, for a little while, but then the water became so high in some places that it was thigh-boots or nothing!
In winter (oct-jan) it's possible to see this phaenomenon:you just have to buy some plastic boots in shoeshops.S.Marco place is one of the lower parts of Venice so, when the High water comes,it's really high and often your boots are not sufficient.In this picture you can see a part of S.Marco place and you see that my boots weren't tall enough!I think it's fun for a tourist,it's so for me too!!
Lorenzoh and me.
Although when we were in Venice the weather was very pleasant, I understand it can flood due to high tides. I don't think this stops the tourists but obviously it would be better to be prepared for it in case you arrived and it was flooded.
Be careful by the places on the shore of the sea!
The stairs are slippery and the water is malodorous and dirty.
Go not too near; it is dangerous to fall into the water!
If you are there at high tide you will find lots of the streets and piazze flooded. There are lots of shops that sell boots to wear just for this purpose.
St. Marks square has a tendency to become flooded, usually between January and March. Be forewarned and prepare yourself. I would bring some appropriate footwear.
