The term 'acqua alta’ (Italian for ‘high water’) commonly refers to the exceptional tidal peaks, which occur periodically in the northern Adriatic Sea, especially in the Venetian Lagoon, and cause flooding. The phenomenon occurs above all in the autumn-spring and with particular meteorological conditions when the sirocco winds coming from the Otranto channel prevent the regular flow of water, or when the bora winds obstruct the outflow of the lagoons and of the rivers of the Veneto coast. The population is alerted when this is forecast.

Surveys and official communications are handled by the ICPSM of the Municipality of Venice (Istituzione Centro Previsione e Segnalazioni Maree).

Based on the updated tide levels received from the ICPSM, AVM/Actv Navigation Operating Center applies an Operative Plan well in advance of the tide levels being reached to guarantee safe waterborne services. In the event of high tide levels, AVM/ACTV will apply changes to the waterborne public transport routes to guarantee a service, except in the case of exceptional tides.  Nevertheless, any assessment to continue the trip safely is always at the discretion of the master of the vessel as well as any consequent restrictions along the route with respect to the rescheduled timetables.

AVM/Actv will inform of any changes to the services through the corporate social media channels @muoversivenezia, the user-info panels at the waterbus stops, through the DIME call center 041 041 and the Infomobilità page.
