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.
