The Direction générale de la météorologie (DGM) has issued a high-level maritime advisory warning of significant oceanic instability and hazardous swell conditions across Morocco’s primary Atlantic and Mediterranean coastlines. Beginning the afternoon of Wednesday, January 28, a powerful meteorological disturbance is expected to catalyze a period of pronounced volatility, characterized by dangerous wave heights and robust wind speeds that could complicate maritime logistics and coastal operations. This shift in atmospheric pressure is projected to impact the kingdom’s critical maritime corridors, necessitating heightened vigilance from commercial shipping interests, port authorities, and coastal infrastructure managers.
The most severe impact is anticipated along the Atlantic littoral, stretching from the northern hub of Tangier southward to the industrial and tourism centers of Agadir. In this expansive zone, the DGM forecasts swell heights originating from the west and northwest to fluctuate between 6 and 7 meters. Such magnitudes represent a substantial risk to near-shore activities and deep-sea transit alike, likely prompting a reassessment of docking schedules and safety protocols at the nation’s major Atlantic gateways. The peak of this oceanic surge is expected to manifest during the overnight hours of Wednesday, creating a particularly challenging environment for nighttime navigation and port security.
Concurrently, the strategic Strait of Gibraltar, a vital artery for global trade and transcontinental connectivity, will not be spared from this atmospheric event. Forecasters anticipate waves ranging from 4 to 5 meters in the Strait, while the Mediterranean coastline—extending from Al Hoceima to Saïdia—is set to experience swells between 3 and 4.5 meters. These conditions are further exacerbated by a significant tidal cycle scheduled for Wednesday and Thursday, with high tide levels projected to reach between 3 and 3.5 meters along the Atlantic front. The convergence of peak swell activity and elevated tides introduces an increased risk of coastal erosion and potential localized flooding in low-lying maritime zones.
Adding a layer of complexity to the navigational outlook, strong to locally intense wind gusts are forecasted to sweep across the region. These winds, predominantly originating from the west and southwest, will affect the Atlantic coast from Tangier to Safi, as well as the Strait of Gibraltar and the Mediterranean shores. The synergy between high-velocity gusts and extreme wave heights creates a high-risk environment for all maritime sectors. However, current modeling suggests that this period of instability will be relatively short-lived; the DGM anticipates a gradual moderation of conditions and an overall improvement in the maritime climate beginning Friday, allowing for a phased resumption of standard coastal and industrial operations.
