How fast a 100-metre ocean swell travels
earth life
In deep water a wave's speed grows with its wavelength: c = √(gλ/2π). A 100 m swell moves at about 12.5 m/s — long waves outrun short ones and arrive first. Worked & sealed by the engine — c = √(9.81·100 / 2π) ≈ 12.5 m/s. [HOLDS; open the seal to re-check.]
