Most extreme rogue wave on record

From Kottke:

This video is a simulation of a rogue wave 58 feet tall recorded by a buoy off the coast of Vancouver Island in 2020.

For centuries, rogue waves were considered nothing but nautical folklore. It wasn't until 1995 that myth became fact.

On the first day of the new year, a nearly 26-meter-high wave (85 feet) suddenly struck an oil-drilling platform roughly 160 kilometers (100 miles) off the coast of Norway.

At the time, the so-called Draupner wave defied all previous models scientists had put together.

Since then, dozens more rogue waves have been recorded (some even in lakes), and while the one that surfaced near Ucluelet, Vancouver Island was not the tallest, its relative size compared to the waves around it was unprecedented.

Scientists define a rogue wave as any wave more than twice the height of the waves surrounding it.

The Draupner wave, for instance, was 25.6 meters tall, while its neighbors were only 12 meters tall.

In comparison, the Ucluelet wave was nearly three times the size of its peers.

Watching the video is surprising... the wave you think is the tall one isn’t and when it comes, you're like, ok, WOW.
