For example, SW'ly winds associated with a
major hurricane off the mid-Atlantic coast of the USA will produce a swell that
reaches Cornwall from WNW.

I once spent an entire day at Praa Sands waiting for an ex hurricane swell, forecast to arrive late morning. The early fast moving & clean waves are often best. On this occasion only 3-4' or so but perfect for surfing & bodyboarding. It was well forecast on the models, I met a chap who'd come from Bristol.
