The long and narrow rectangular shape of the Adriatic Sea is the source of an oscillating water motion (called seiche) along the basin's minor axis. [5]The principal oscillation, which has a period of 21 hours and 30 minutes and an amplitude around 0.5 meters at the axis' extremities, supplements the natural tidal cycle, so that the Adriatic Sea has much more extreme tidal events than the rest ...
Venice was hit Sunday by a record third exceptional tide in the same week while other parts of Italy struggled with a series of weather woes, from rain-swollen rivers to high winds to an out-of ...
Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...
Surf forecasting is the process of using offshore swell data to predict onshore wave conditions. It is used by millions of people across the world, including professionals who put their forecasts online, meteorologists who work for news crews, and surfers all over the world.

When a high tide is forecast, compressed air is introduced into the gates to empty them of water, causing them to rotate around the axis of the hinges and rise up until they emerge above the water to stop the tide from entering the lagoon. When the tide recedes, the gates are filled with water again and lowered into their housing.
The most extreme are the spring tides known as the acqua alta (Italian for "high water"), which regularly flood much of Venice. The nearby Marano-Grado Lagoon , with a surface area of around 160 square kilometres (62 square miles), is the northernmost lagoon in the Adriatic Sea and is sometimes called the "twin sister of the Venice lagoon".
