The Most Extreme Rogue Wave Ever Recorded—Captured Off the Coast of Canada

Off the coast of Canada, the most extreme rogue wave ever recorded was captured. In November 2020, a colossal and unexpected wave surged off the coast of Vancouver Island, Canada, capturing the attention of scientists worldwide. The most extreme rogue wave ever recorded in terms of proportionality, this one near Ucluelet, British Columbia, reached a staggering height of 17.6 meters (58 feet).

What Is a Rogue Wave?

Rogue waves, also known as freak or killer waves, are unusually large and sudden waves that appear unexpectedly on the ocean's surface. They are typically more than twice the height of surrounding waves and can be extremely dangerous due to their unpredictability. Rogue waves can occur far from the shore and are caused by wind and ocean currents, in contrast to tsunamis, which are caused by seismic activity. Victoria Buzz+1Victoria Buzz+1

The Record-Breaking Wave

On November 17, 2020, a MarineLabs sensor buoy located approximately 7 kilometers (4.3 miles) off the coast of Ucluelet recorded a rogue wave measuring 17.6 meters in height. At the time, the surrounding sea state had average wave heights of about 6 meters, making this rogue wave nearly three times the size of its neighbors. This event was deemed a once-in-1,300-year occurrence by researchers at the University of Victoria, who analyzed the data from the buoy.

Scientific Significance

The study, published in Scientific Reports, highlighted the rarity and magnitude of the Ucluelet rogue wave. Lead researcher Dr. Johannes Gemmrich noted that such extreme rogue waves are rarely observed directly, especially in high sea states. The Ucluelet wave's disproportionate size compared to surrounding waves set a new benchmark for understanding these phenomena.

Implications for Marine Safety

While the rogue wave occurred offshore and caused no damage, its occurrence underscores the potential dangers rogue waves pose to maritime activities. Their sudden appearance and immense power can be perilous for vessels, especially those operating near coastal areas. The data collected from such events are crucial for improving early warning systems and enhancing the safety of maritime operations.

Conclusion

The rogue wave recorded off the coast of Vancouver Island in 2020 stands as a testament to the ocean's unpredictable and formidable nature. Its unprecedented size and the circumstances of its occurrence provide valuable insights into the dynamics of rogue waves and their potential impact on marine environments. Continued research and monitoring are essential to better understand these phenomena and mitigate their risks to maritime safety.

The Building Blocks of a Monster Wave The rogue wave off the coast of Ucluelet wasn’t just big—it was statistically outrageous. At 17.6 meters (58 feet) tall, the wave towered over the sea state, where typical wave heights were closer to 6 meters. That’s like a six-story building suddenly rising from the sea and then vanishing in moments.

This wave's extreme proportionality was more than just its size. According to researchers, it was about three times the height of its surrounding waves—qualifying it as one of the most disproportionate rogue waves ever recorded. Scientists use this ratio to define a rogue wave, which typically has a height at least 2.2 times higher than the average waves in the area. How Did We Even Catch It?

A sensor buoy operated by MarineLabs Coastal Observations, a Canadian technology company specializing in coastal data monitoring, captured the wave. The network of buoys is part of a growing trend of smart ocean technology that collects real-time data on the state of the sea. Scientists are now able to detect these anomalies in close to real time, something that wasn't possible until a few decades ago. This is made possible by GPS tracking sensors and high-frequency sampling sensors. Without ever putting a ship in danger, scientists were able to gain unprecedented insight into this rogue wave by measuring it digitally rather than using the human eye. Not Just a Freak Occurrence

Though this wave has been deemed a once-in-1,300-years event statistically, rogue waves themselves may not be as rare as once believed. Over the course of many centuries, sailors have told tales of bizarre waves that would "come out of nowhere" and slam into even the most seaworthy vessels. These stories were often dismissed as maritime myths—until hard data like the Ucluelet wave proved otherwise.

In fact, one of the first scientifically recorded rogue waves occurred in 1995, when an oil platform in the North Sea registered a 25.6-meter wave (the famous "Draupner wave"). That was a turning point that brought rogue waves closer to scientific reality than they had ever been before. Could it occur once more? Absolutely. Because of this, research in this area is moving quickly. Climate change, shifting wind patterns, and more frequent extreme weather events are likely to influence the formation of rogue waves. Areas like the North Pacific—especially off the coast of British Columbia—are particularly vulnerable due to strong currents and storm systems.

Researchers hope that with a growing network of smart buoys and machine learning models, they’ll eventually be able to predict rogue wave hotspots and warn ships in advance. For now, detection remains the best tool in the fight against these oceanic giants.

The rogue wave off Ucluelet was a spectacular reminder of just how little we know about.
