Re: Tide article

It seems to me that these 'co-tidal plots', animations and such are
demonstrating that there IS a strong correlation between the moons
'location' and local tides.

EVERY location in the ocean has a strong moon driven component to
it's tidal variations. Sure,
not MANY locations have the IDEAL correlation of a high tide
occurring at the time when the moon is directly overhead (or 180
degrees away from overhead). But EVERY location has a stong 12.4 hour
component to it's tides. It's the PHASE of the correlation that seems
to vary wildly.

Or so it seems to ME!

Moon frequencies and local tidal frequency ie high water does not occur at
a constant regular interval -- I would like to say "anywhere" but I
don't really know that that is precisely true.
The NewZeland site plots the main Moon component, M2.

However, in addition to the above, you are quite correct that there is --
again I would like to say "never" -- a correlation of the position of the
Moon with local high water.
