This list of rogue waves compiles incidents of known and likely rogue waves – also known as freak waves, monster waves, killer waves, and extreme waves. These are dangerous and rare ocean surface waves that unexpectedly reach at least twice the height of the tallest waves around them, and are often described by witnesses as "walls of water". They occur in deep water, usually far out at sea, and are a threat even to capital ships, ocean liners and land structures such as lighthouses.

Shallow-Water Observations of Rogue Waves, Height Distributions, and Spectral Moments. Abstract Wave height distributions in the shallow nearshore region are mainly inferred from idealized laboratory experiments or numerical studies. Here, we show that these findings do not represent real-world conditions of swell-dominated shallow nearshore regions. Long-term, high-resolution pressure records are converted to surface elevation time series based on a shallow-water nonlinear transfer function. The fixed-point observations cover a wide range of wave nonlinearities, quantified by the Ursell number, 2 < Ur < 245. Wave height distributions, crest height distributions, and spectral moments are in…
