Ever Hear of a Cross Sea?

Posted by Kyle Brookings on Sunday, February 17, 2019

A cross sea appears as squares in the ocean.

A cross sea has a large amount of directional spreading. This may occur when water waves from one weather system continue despite a shift in wind.

Waves generated by the new wind run at an angle to the old, creating a shifting, dangerous pattern.

Two weather systems that are far from each other may create a cross sea when the waves from the systems meet, usually at a place far from either weather system. Until the older waves have dissipated, they create a perilous sea hazard.
