Interesting, much overlooked and so far as I know, still unexplained
natural phenomenon.

Assuming that you are referring to the first paragraph on that page, I
think this would be the effect of the sea breeze, caused by the land
heating up faster than the sea during the day and cooling down faster at
night.

But a phenomenon with such a mild(ish) induction process would be
quickly over ridden by a more persuasive set-up such as a weakish Low or
a moderate High.

The paragraph reads:

Says Westy: "...and they expect the wind to flow the same way near the
shore as it does a mile or so out. They don't know that wind always
favours the shore at right angles."

(Author's note: This is also true. Wind, whether off shore or onshore,
if blowing at an angle to the shore, always tends to shift and head
directly into or out from the straight line of the shore.)

I believe the same is true of breakers. I think that such a tendency can
build up to give the phenomenon where every so many waves, there is a
much larger one.

(Each wave hits the shore and is reflected at a slightly more open
angle. Every 7 to 12 or so waves the swell and its counter are in
harmony. Not too sure about that explanation.)


The way I read that is that no matter what the cause of the wind, the
tendency is for it to flow perpendicular to the shoreline.

First of all is this really so?

If it is then how is that accomplished? The phenomenon you describe is
one caused by temperature differences causing pressure changes
especially noticeable between day and night.

At sea the wind direction is some 15 degrees off the heading to or from
the centre. Presumable the way land interferes stops that being as true?
Local warm/cool spots, altitude changes, barriers and whatever?
