Next spring tide on Sat 02 May (range 0.9m). Next neap on Tue 28 Apr.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

Venice sits in a 550 km² lagoon at the head of the Adriatic, separated from the open sea by a chain of three barrier islands — the Lido, Pellestrina, and the Cavallino-Treporti littoral. The tide here is the largest in the Mediterranean by some distance and the defining feature of the city's life. Mean range at the Punta della Salute gauge in central Venice is about 0.6 metres, climbing close to 0.9 metres on the largest spring tides. The pattern is semidiurnal, two highs and two lows about twelve and a half hours apart. The lagoon connects to the open Adriatic through three inlets — the bocche of the Lido, Malamocco, and Chioggia — and the MOSE flood barriers across each can be raised when surge events threaten central Venice. The phenomenon of acqua alta is the city's signature tidal event: when a spring tide coincides with low atmospheric pressure and a sustained sirocco wind from the south, water levels stack significantly above the predicted high. The November 2019 acqua alta peak ran about 187 cm above the local datum — the second-highest on record after the 194 cm event of November 1966 that flooded over 80% of the historic centre. The November 12, 2019 event flooded San Marco, damaged churches, mosaics, and ground-floor businesses across the city. Walkways flood, raised passerelle go up, and the bell of St Mark's campanile rings warning.
