Massive Wave in The Pacific Was The Most Extreme 'Rogue Wave' on Record
Researchers say buoy data show rogue waves are far rarer and more extreme than models predict, with a possible early-warning signal in 75% of cases.
- In November 2020, a freak wave off British Columbia lifted a lone buoy 17.6 meters high. Physicist Johannes Gemmrich from the University of Victoria explained, "Proportionally, the Ucluelet wave is likely the most extreme rogue wave ever recorded."
- Scientists define a rogue wave as any wave more than twice the height of surrounding waves. The Draupner wave in Norway previously set the standard at 25.6 meters tall, with neighbors only 12 meters high.
- MarineLabs deployed dozens of buoys to monitor deep-sea hazards, capturing an event thought to occur only once every 1,300 years. The company noted these "walls of water" can make rogue waves incredibly dangerous to marine operations.
- Researchers from the University of South Florida published a new analysis in February 2026 identifying a potential early-warning sign for rogue waves. They found a sharp dip in wave correlation often precedes a rapid rebound right before a wave hits.
- A 2020 study predicted that wave heights in the North Pacific will increase with climate change, suggesting the Ucluelet wave may not hold its record for long. This raises long-term risks for coastal communities.

In November 2020, off the coast of Canada, a solitary wave exceeding the height of a four-storey building arose in the North Pacific, a phenomenon of extreme rarity, which only occurs statistically once every 1,300 years.
In November 2020, an extraordinary natural phenomenon occurred off the coast of Vancouver Island, Canada, and could have gone almost unnoticed. The sudden...
The giant wave in the Pacific came out of nowhere and threw a sea buoy at the heights, leaving many people mouth-open with the size of the event. This water wall on the coast of Canada became the most extreme record of history and proved that the sea hides absurd mysteries. What makes this giant wave...
In November 2020, a spectacular ocean anomaly occurred off British Columbia, lifting a buoy at nearly 18 metres in height. This four-storey "water wall" has just been confirmed as the most extreme scelerate wave ever recorded in proportion to its immediate environment. Although the phenomenon is ...
