Attica

Attica is the Greek peninsula that runs from the Corinth canal in the west out to Cape Sounion at the south-eastern tip, with Athens at its centre and the port of Piraeus on its southern coast facing the Saronic Gulf. The tide here is the small Mediterranean signal characteristic of the eastern basin: mean range at Piraeus is about 0.15 metres, with spring tides reaching close to 0.25. The astronomical signal is small enough that meteorological tide — pressure changes from passing weather systems, the meltemi etesian wind in summer, sirocco events in winter — typically dominates day-to-day water-level variation. The Saronic Gulf island chain (Aegina, Salamis, Hydra, Spetses) and the Cyclades further south all run the same near-flat tidal regime. What matters more on a practical level is current at narrow passages and the boat-traffic surge inside Piraeus harbour. Solunar fishing windows and the tradition of reading the moon for octopus and squid fishing remain part of the local tide-time interest, even where the height swing itself is tiny. Open-Meteo Marine drives the gridded predictions on this site; the Hellenic Navy Hydrographic Service is the authoritative Greek tide source.
