the simplest way to explain is:
kite when the tide is running opposite to the wind. you figure out the rest, it's not that hard.

that is ok if you want to kite straight downwind and into the beach once because when you kite back out you are kiting with the tide

if you were kiting straight downwind then you would be going AGAINST the tide. amd if you were kiting with the tide you would have to go straight upwind (cant do that)
when you're kiting you would be going 90 / 90.
this is at a rivermouth!

all good mate!

maybe i should say water height and not tide as they are not one and the same.

Tides are the rising and falling of Earth's ocean surface caused by the tidal forces of the Moon and the Sun acting on the oceans. Tidal phenomena can occur in any object that is subjected to a gravitational field that varies in time and space, such as the Earth's land masses. (see Other tides).
en.wikipedia.org/wiki/Tide

You still sure storm surge 'has an effect' on tide? Or 'water height' perhaps?

Reading comprehension may help here.
pat said "tide predictions are correct to the minute", I responded by pointing out they are not always right. In practice: atmospheric conditions effect them and in some places and at some times the effect can be significant. Hence when a sea breeze causes a dramatic effect or change on the atmospheric conditions; huge air masses descend over the deep oceans, as they cool their weight per volume changes [volume remains constant, temperature decreases and pressure increases, resulting in it weighing more] and due to the intermittent nature of the coast line[Being a convergence zone between pressure extremities]: wind, pressure and tidal movement; fluctuations in the water level arise.

The only thing I was saying to start with was people may see the correlation between what appears to be the changing of the tide and the bringing of a seabreeze and believe it to be true when the cause and effect are reversed. This in no way answers the original question as to whether it causes the seabreeze but that is a well documented event that is being diluted with examples from other countries that do take tide into effect such as in Florida where the Gulf stream has a considerable hold over the seabreeze.



BTW; Thanks for the personal attacks on my Dad, Yes, he is going back to uni but it's actually because he's on the staff, more in a honorary position though. He was the guy who that the group that got the glory for finding the Sydney contracted to do the survey and get the images from two thousand and something meters it sits at. But hell, I don't know anything about digging holes so I shouldn't comment on this at all anyway.
