The coastal and oceanic conditions off of northern Peru create a “dreamland for surfers.”
The waters off the Pacific coast of northern Peru routinely build what has been called the world’s longest wave. There’s no way to know for sure, but the seemingly endless waves that roll up to the fishing town of Puerto Malabrigo (Chicama) are legendary among surfers. While some famous wave breaks around the world can be ridden for seconds, the breaks at Chicama can be ridden for minutes.
The swells responsible for Chicama’s famous waves are visible in this image, acquired on March 23, 2021, with the Operational Land Imager (OLI) on Landsat 8. Notice the row after row of the waves neatly lining up as they approach the coast.
According to Andrew Thomas, an oceanographer at University of Maine and ex-surfer, the swell is generated by storm systems and weather fronts hundreds to thousands of miles away in the Pacific Ocean—and occasionally the Southern Ocean. As the waves propagate across the open water, waves of similar wavelengths (and speed) become sorted and start to travel together. “Because the coast of Peru is very deep,” Thomas said, “these large swells will continue their journey until very close to shore.”
