About tides at Lisbon (Tagus mouth)

The Tagus opens to the Atlantic at Cascais and runs deep into the city of Lisbon, with the tide pushing well past the 25 de Abril bridge before it loses force. Mean range at the river mouth is about 2.4 metres, semidiurnal, with two highs and two lows about twelve and a half hours apart. Spring tides reach close to 3.5 metres at Cascais and the lower estuary; neaps drop near 1.5 metres. The river current adds to the ebb, sometimes notably so, and the morning land breeze in summer can bend the surface against an incoming tide. For anyone walking the riverside in Belém, paddleboarding from Algés, or watching the surf at Costa da Caparica across the bay, the timing of the swing matters. Caparica's beach narrows on the high — sand width can shrink by 30 m or more — and widens again on the low. Predictions on this page come from Open-Meteo Marine, a gridded global model. Useful indication for planning, but not navigation-grade — the Portuguese hydrographic institute (Instituto Hidrográfico) operates the authoritative gauges and publishes tide tables for the Tagus.

Common questions about tides at Lisbon (Tagus mouth)

When is the next high tide at the Tagus mouth?
The hero block shows the next high tide at the lower Tagus near Cascais in local Lisbon time. The 7-day table covers daily extremes for both ends of the swing. Note that high water at Lisbon city centre (Cais do Sodré) lags the river mouth by 30–60 minutes depending on river discharge.
What's the typical tide range at Lisbon?
Mean range is about 2.4 metres at the Tagus mouth. Spring tides — around new and full moons — push toward 3.5 metres, the biggest tides on the Iberian Atlantic coast. Neap tides compress the swing to around 1.5 metres. The big swings of the year happen at the equinoxes when astronomical forcing is strongest.
Where do these tide predictions come from?
Open-Meteo Marine, a global ocean-grid model (MeteoFrance SMOC, 0.08 degree). Gridded model output — useful for planning around the Tagus, but not navigation-grade. For the authoritative Portuguese tide data including the official Lisbon and Cascais gauges, see Instituto Hidrográfico (IH) tide tables.
Why does the tide affect Costa da Caparica's beach width?
Caparica is a long open Atlantic-facing beach with a relatively gentle slope, so the difference between high and low water shifts the waterline horizontally by 30 m or more on a typical day, and further on spring tides. Strong onshore swell and wind setup can make the high look bigger still. Walk the beach at low water for the widest sand.
Is this safe to use for navigation?
No. For piloting on the Tagus or the Portuguese coast, use Instituto Hidrográfico's authoritative tide tables and chart products plus the latest navigational warnings. Open-Meteo's gridded predictions are useful general planning data, not a navigational source.
