Algiers, Algeria – Coastal communities across Algeria are on alert as the National Meteorological Office (ONM) issued a yellow-level warning on Monday, October 27, 2025, cautioning of significant wave activity along a large swathe of the nation’s Mediterranean coastline. The alert, signaling a heightened risk of marine hazards, spans the entire coastal stretch from El Kala, near the Tunisian border, to Beni Saf in the west, close to the border with Morocco. This extensive warning covers a substantial portion of Algeria’s northern seaboard, encompassing numerous heavily populated cities and vital port infrastructure.
The ONM’s advisory indicates that the high waves are expected to persist throughout Monday and into Tuesday morning, potentially impacting maritime activities, fishing operations, and coastal infrastructure. Residents and visitors in the affected areas are urged to exercise extreme caution near the shoreline and to avoid engaging in water sports or any activity that could expose them to the dangers of the rough seas.
The yellow-level warning signifies a moderate risk of hazardous weather conditions. While not as severe as orange or red alerts, it still necessitates vigilance and preparedness, particularly for those whose livelihoods or recreational activities are closely tied to the sea. The ONM regularly monitors weather patterns and issues alerts to provide timely warnings to the public and relevant authorities, enabling them to take appropriate preventative measures.
“We are closely monitoring the situation and advising all coastal communities to remain vigilant,” stated a spokesperson for the ONM. “The high waves pose a risk to small vessels, swimmers, and individuals near the coastline. We urge everyone to heed the warnings and avoid unnecessary risks.”
The potential consequences of high wave activity can include coastal erosion, damage to seawalls and other protective structures, and disruption to maritime traffic. Fishing boats are particularly vulnerable, and many fishermen along the affected coastline have reportedly suspended their operations for the duration of the alert. Ports are also implementing safety protocols to ensure the secure berthing of ships and the safe handling of cargo.
The ONM’s warning comes at a time when Algeria’s coastal regions are experiencing increased tourism activity. With mild autumn weather prevailing, many Algerians and foreign visitors are drawn to the beaches and coastal resorts. However, the presence of high waves underscores the importance of prioritizing safety and adhering to official advisories. Local authorities are stepping up patrols along beaches and promenades to warn people of the potential dangers and to enforce restrictions on swimming and water sports.

Beyond the immediate risks to human safety, the high wave activity could also have longer-term environmental implications. Increased erosion can damage coastal ecosystems, leading to habitat loss and impacting biodiversity. Rising sea levels, exacerbated by climate change, are already contributing to coastal erosion in many parts of the world, and events like this serve as a reminder of the vulnerability of coastal communities to the impacts of changing weather patterns.
The Algerian government has invested significantly in coastal protection measures in recent years, including the construction of seawalls, breakwaters, and other infrastructure designed to mitigate the effects of erosion and storm surges. However, the effectiveness of these measures is constantly being tested by the forces of nature, and ongoing monitoring and maintenance are essential to ensure their continued performance.
The ONM is expected to provide updated forecasts and warnings as the situation evolves. Residents and visitors in coastal areas are encouraged to stay informed by monitoring official weather reports and following the advice of local authorities. The current alert serves as a reminder of the power of the sea and the importance of respecting its forces, particularly in vulnerable coastal environments.
This event also highlights the growing need for improved coastal management strategies and increased investment in climate change adaptation measures. As global temperatures continue to rise and sea levels continue to climb, coastal communities around the world will face increasing challenges in protecting their populations, infrastructure, and natural resources. Algeria, with its extensive coastline and growing coastal population, is no exception. A proactive and comprehensive approach to coastal management is essential to ensure the long-term sustainability of the nation’s coastal regions. The current weather event provides a stark reminder of the urgency of addressing these challenges.
The alert remains in effect until further notice, and the ONM is urging continued vigilance and caution among all those living or working near the Algerian coast. Updates will be provided as new information becomes available.
