A Coruña, Galicia tide times

The hero block shows the next high tide at A Coruña in local Madrid time (CET in winter, CEST in summer). The 7-day table covers all four daily extremes. Galicia's tide arrives at the open coast first and propagates inland up the rías; high water at the head of a ría typically lags the open coast by 30 to 60 minutes.

Mean range at the harbour is about 2.7 metres, the largest in Spain. Spring tides push close to 4 metres at the equinoxes, neaps drop close to 1.2 metres. The Iberian Atlantic runs larger swings than the Mediterranean side because the open Atlantic tide propagates cleanly to this coast — the Mediterranean sees almost no astronomical tide because the basin is nearly enclosed.

Open-Meteo Marine, a global ocean-grid model (MeteoFrance SMOC, 0.08 degree resolution). Useful for general planning around the harbour and the city beaches, but not navigation-grade. For authoritative Spanish tide data, Puertos del Estado runs the official Galician gauge network including A Coruña and Vigo.

A ría is a drowned river valley — a coastal inlet flooded by sea-level rise. Galicia is famous for them. Tide propagates into a ría from the open coast as a free wave, the height typically grows slightly on the way upstream because the channel narrows, and the timing lags the open coast by 30 to 60 minutes depending on the ría's length. The Rías Baixas (Vigo, Pontevedra) and Rías Altas (A Coruña, Ferrol) each behave like a tide-amplifier on the way in.

No. For piloting in or out of A Coruña harbour, working the rocky cliff coast at the Costa da Morte, or harvesting percebes on the cliff bases use Puertos del Estado's authoritative tide tables, the Instituto Hidrográfico de la Marina chart products, and the latest Spanish coastguard notices. The Costa da Morte name is not idle — the cliff-base shore breaks hard on a westerly swell and is a working hazard, not a planning matter.
