Next spring tide on Sat 02 May (range 2.4m). Last neap on Mon 27 Apr. 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.

Casablanca fronts the Atlantic on Morocco's central coast, the country's largest city and its working economic capital with the busiest port in the Maghreb on the broad sandy bay just south of the Bouregreg river mouth at Rabat. The Hassan II Mosque sits on a platform built directly out into the surf at the western edge of the city corniche, with the prayer-hall floor laid above the breaking Atlantic so that the architectural intent draws on the Quranic verse about God's throne above the waters; the platform is a tide-cycle landmark in itself, with the swell breaking against the seaward esplanade at every flood. The tide here is a moderate semidiurnal signal that the open Atlantic delivers cleanly to the African shore: mean range at the Casablanca port gauge is about 2.3 metres, climbing past 3.6 metres on the largest spring tides and dropping near 1.3 on neaps. The pattern is two highs and two lows of comparable size about twelve and a half hours apart. The country's long Atlantic-facing coast runs an open-ocean swell regime that builds the famous Moroccan surf culture — Anchor Point and Boilers up the coast at Taghazout further south are the marquee waves, but Casablanca's Dar Bouazza, Bouznika, and the Mohammedia beachbreak all hold their own days and the right swell turns the Aïn Diab corniche into a working surf coast. The historical context that anyone reading the Casablanca tide table sooner or later collides with is the 1755 Lisbon earthquake — the magnitude-8.5 event that levelled Lisbon also generated a transoceanic tsunami that reached the Moroccan coast within an hour, and contemporary records describe wave heights at Salé and Casablanca exceeding ten metres. The same fault system remains active and the long Atlantic-facing coastline remains a recognised tsunami risk zone with the Centre National pour la Recherche Scientifique et Technique (CNRST) operating the surveillance network. The working container traffic at the port handles the bulk of the country's trade and tide-time matters for the dredged-channel approach windows; the long sand at Aïn Diab, the surf at Dar Bouazza, the corniche running west toward Mohammedia, and the medina-edge fishing port all read the table for different windows. Open-Meteo Marine drives the gridded predictions on this page; for authoritative Moroccan tide data, the Service de l'Hydrographie et de la Cartographie Marocain publishes the official tide tables and operates the port reference gauge.
