Casablanca-Settat

Casablanca-Settat fronts the Atlantic on Morocco's central coast from the Bouregreg river mouth at the Rabat boundary in the north south through Casablanca's working port and the long sand-and-cliff coast at Mohammedia, Dar Bouazza, and Tamaris toward the El Jadida line. 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 Mohammedia all hold their own beach-break days. The 1755 Lisbon earthquake generated a transoceanic tsunami that struck the Moroccan coast within an hour, and historical records describe wave heights at Salé and Casablanca exceeding ten metres — the same event that levelled Lisbon also rearranged the Moroccan littoral. The working port at Casablanca handles the bulk of the country's container traffic and tide-time matters for the dredged-channel approach windows; the open-ocean swell across the harbour entrance and the long sand at Aïn Diab read the table for different windows.
