Well, if there's no indication of a tsunami, nor an earthquake in the
oceanbottom; how is the phenomenon Roger described and started this
thread
to be explained? Or is it just imagination?

I still think it's a long wavelelength swell, which weather system
created
it is open to debate.

Yes, I'd agree with that as the only possible explanation. Such swell can
travel vast distances and retain the most important wave features. Swell
waves become very smooth and regular, and lack the irregularities seen in
waves nearer the generating zone. Knowing their frequency/time period
might help confirm that idea.

Thank you, Mike and Graham
Of course I'm not familair with the coast line near Eastbourne nor northern
Cornwall; but is it a bad thought this long wave swell is more obvious in
deep water along the British coastline than the far more shallow North Sea
coasts of Holland and Belgium, with its sandbanks? A swell like this would
disappear in the wide surf. Apart from that a swell coming from the south;
flowing through the Channel and the street of Dover, it would spread out
into the North Sea, losing lots of its amplitude??
Wondering, as I put up the subject in a Dutch/Belgium weatherforum, just to
ask if this phenomenon is known by someone along our coasts, but they
thought I was drunk )
