In Biarritz, the postcard of August turns into an action film: under the effect of the ex-hurricane Erin, a cyclonic swell drives giant waves of 4 to 5 meters towards the coast. The Submersion wave alert system is activated, red flags hoisted and beaches closed, while the peak is expected between 7 PM and 8 PM at high tide. A fascinating spectacle… to be admired from solid ground.
Biarritz is experiencing an exceptional episode: giant waves of 4 to 5 meters are crashing in the middle of the season, a consequence of a cyclonic swell generated by the ex-hurricane Erin. The town hall activates its Submersion wave alert system, the closed beaches display the red flag, and the terraces as well as the seaside equipment are protected. The peak is expected between 7 PM and 8 PM with a high tide and a high coefficient, while the lifeguards keep watch and seasoned surfers are already eyeing Guéthary and the legendary Belharra. A fascinating spectacle, as much as a real danger, that revives memories of great submersions.
An ocean under the effect of Erin: when the swell crosses the Atlantic
Having left the shores of the American east coast, the ex-hurricane Erin has headed towards Europe, transforming into a vast depression that lashes the open sea. The result: a wave engine in the open sea, with sustained winds producing a long, powerful, and perfectly aligned cyclonic swell to strike the Basque Coast. This is not the swell of an ordinary August afternoon: it is an energetic package, coming from afar, that knows how to find bays and breakwaters at their most vulnerable moments.
Timings, areas, and key figures of a much-anticipated peak
Along the entire coastline, from the Basque Coast to Charente-Maritime, the maximum intensity is expected between 7 PM and 8 PM, synchronized with a high tide at a strong coefficient (close to 86). It is on the Basque fringe that the swell should fully manifest, with waves locally reaching 4 to 5 meters. In certain passes and constricted areas, backwash can amplify the amplitude and surprise well beyond the high-water line.
Wave-submersion alert: the municipal plan accelerates
The city has activated its graduated system from 1 to 6 for the risk of submersion waves: level 3 in the morning, then escalating to level 4 from 5 PM. The goal: anticipate, protect, restrict if necessary. This protocol, usually reserved for winter swells, is being invoked for the first time in the heart of the peak season, a testament to the magnitude of the episode.
Closed beaches, red flag hoisted: safety before the spectacle
The red flag flies all day long. Translation: no swimming, no bodyboarding, no paddle, no water entry, even “just to see.” The lifeguards patrol and remind the daring of the rules, as a set can come in unexpectedly and throw a swimmer onto the rocks or pull them out to sea by a very strong rip current.
Terraces covered, sandbags, and mechanical shovel maneuvers
Terraces of cafes, beachfront restaurants, municipal pool, tourist train running along the ocean, and surf schools: everything is at a standstill. On the Grande Plage, a true ballet has taken place: mechanical shovels, big bags filled with sand, barriers hastily set up. A paradoxical scene under a serene sky and a sometimes smooth sea during the day, while the evening promises breaking waves capable of spraying the platform.
Submersion: a word that recalls salty memories
The imperial city has not forgotten the damage caused by a series of waves along the shore a few years ago. More recently, passersby were knocked over by a wave that breached the wall near the Rock of the Virgin. The message is simple: even far from the water, even behind a parapet, a submersion wave can surprise and disrupt.
Experienced surfers: between fascination and red line
Discussions are lively among enthusiasts: a meeting at Guéthary, where the big surf spots have their regulars, and the fantasy of Belharra, that liquid mountain nestled three kilometers off the coast of Saint-Jean-de-Luz. However, this episode remains unprecedented for summer, and restrictions apply. To dream without daring the danger, one can explore the best surf spots around the world and prepare, in peace, for the next epic session.
Useful advice for a thundering coastline
Stay away from rock formations, breakwaters, and ends of promenades, avoid selfies on the quay, and refrain from family proximity games: the sea always wins. If you observe the spectacle, position yourself at a height and respect safety perimeters. Drivers, park away from the seaside fronts. And if you crave the salty air, prefer a walk on the heights rather than at the water’s edge.
City atmosphere: between postcard and heralded crash
Holidaymakers sprawled on their towels, sun high, sea almost docile… and, a few meters away, municipal machines building makeshift ramparts. Biarritz lives a scene worthy of a film: the before, peaceful, and the after, orchestrated by a swell waiting only for the right tide phase to show its power. A forecaster from Météo-France explains it: the encounter between a powerful swell and a well-aligned tide is the perfect equation for a spectacular episode.
To prolong the escape without taking risks
If the ocean demands a step back, the desire for escape can be satisfied differently. Head towards ideas for beaches, landscapes, and delights for inspiration without getting wet, an adventure in Andalusia, Morocco, or Portugal when the trade winds are gentler, or even the discovery of the Maldives and their activities to cultivate the passion for blue. Lovers of preserved coves will cast an eye towards the hidden creeks of the pink granite coast, perfect for dreaming of the open sea… from a peaceful shore.
