The beaches of Quequén woke up covered by enormous amounts of sea foam after the intense storm that affected the Buenos Aires coast. The phenomenon extended over several kilometers and transformed the coastal landscape into an unusual scene that quickly went viral on social media.
On Saturday morning, locals and tourists walked along the coast to observe the phenomenon generated after the passage of an extratropical cyclone that caused strong gusts of wind, intense rains, and swells over the Atlantic.
Additionally, the extreme weather conditions particularly affected towns between Mar del Plata and Necochea, where large waves, flooding, and damage were recorded in various urban and coastal sectors.
While the rain persisted, numerous videos showed how the wind lifted the foam and carried it across streets and beaches, creating striking images that caught attention throughout the region.
A natural phenomenon driven by strong waves
The sea foam forms naturally when the ocean concentrates organic matter such as remnants of algae, mineral salts, proteins, and other compounds present in the water.
In this case, the intense movement generated by the cyclone agitated large amounts of organic matter accumulated in the sea. As a result, the waves incorporated air into that mixture and created extensive layers of foam along the coast.
Moreover, the combination of swells, persistent wind, and strong waves favored the expansion of the phenomenon towards urban areas near the beach. The gusts even caused part of the foam to be carried through the air for several hours.
Experts indicate that such episodes are usually temporary and do not pose toxic risks to people. However, their appearance reflects the intensity of the meteorological conditions that affected the Buenos Aires Atlantic coast.
The impact of storms on the Buenos Aires coasts
The extreme weather phenomena are increasingly concerning in coastal cities due to the impact they have on beaches, infrastructure, and marine ecosystems.
The southeasters, extratropical cyclones, and intense swells accelerate coastal erosion processes and alter the natural dynamics of the beaches. Additionally, large waves can carry sediments, debris, and organic matter to the surface.
In various localities along the Buenos Aires coast, the recent storms caused flooding, damage to homes, and complications in urban sectors near the sea. This is compounded by the increasing vulnerability of the coasts to the rise in extreme weather events.
Therefore, environmental specialists emphasize the importance of strengthening coastal adaptation strategies, dune conservation, and ocean monitoring to reduce risks and protect marine ecosystems.
What is sea foam and what factors generate it?
The sea foam is a natural phenomenon that appears when the water concentrates high amounts of organic compounds produced by algae, plankton, and marine microorganisms. These substances act as foaming agents when the sea is intensely agitated.
One of the main factors for its occurrence is strong waves. The waves break the algae and mix air with the suspended organic matter, forming bubbles that accumulate on the surface and reach the coast.
Additionally, strong winds and swells help expand the foam over beaches and nearby urban sectors. Storms and extratropical cyclones often enhance this process due to the violence of the water movement.
Environmental factors also influence, such as the sea temperature, the presence of nutrients, and the accumulation of organic remnants. Under certain conditions, these elements can favor more abundant and visible sea foam episodes, especially after intense storms.
