why does the maximum hight of the tide differ from place to place and day to day?

The tide is governed by the motions of the Moon orbiting Earth, and Earth orbiting the Sun, Each of which has a gravitational influence on the Earth. When the Moon and Sun are in line, (ie) new Moon, the tides are higher than usual.Then, when you take into account the geographical situations along coast lines, like gulfs, inlets, etc. the tidal effects can be more pronounced.

It is the area of land that is underwater for half the day and above water the other half. This is caused by the rise an fall of sea levels due to high and low tides.

The tide is the cyclic rising and falling of Earth's ocean surface caused by the tidal forces of the Moon and the Sun acting on the Earth. Tides cause changes in the depth of the sea, and also produce oscillating currents known as tidal streams, making prediction of tides important for coastal navigation (see Tides and navigation, below). The strip of seashore that is submerged at high tide and exposed at low tide, the intertidal zone, is an important ecological product of ocean tides.\n\nThe changing tide produced at a given location on the Earth is the result of the changing positions of the Moon and Sun relative to the Earth coupled with the effects of the rotation of the Earth and the local bathymetry (the underwater equivalent to topography). Though the gravitational force exerted by the Sun on the Earth is almost 200 times stronger than that exerted by the Moon, the tidal force produced by the Moon is about twice as strong as that produced by the Sun. The reason for this is that the tidal force is related not to the strength of a gravitational field, but to its gradient. The field gradient decreases with distance from the source more rapidly than does the field strength; as the Sun is about 400 times further from the Earth than is the Moon, the gradient of the Sun's field, and thus the tidal force produced by the Sun, is weaker.

its called high tide and low tide it has to do with the gravitational pull on large bodies of water.

Actually only about 2/3 of the tides are from the moon's gravity, and about 1/3 are from the sun's gravity. \n\nThe reason there are about 2 high tides per day, is that the gravity field produced by the sun and the moon is not constant. The farther away from the moon you are, the less the gravity is. So water close to the moon gets pulled away from the earth (the force on the earth is less since the earth is farther away) and it gets pulled up in a pile we call a high tide. On the other side of the earth, the earth is pulled away from the water (since the earth is closer to the moon than the water on that side of the earth), leaving a pile of water on the far side of the earth, which is the other high tide. \n\nIn between these two piles of water, there are places where the water is not getting piled up. We say those places are experiencing a low tide. \n\nIt gets much more complicated than this of course. There are tides in the ground and in the atmosphere, in lakes and in rivers etc. There are places where there is one high tide a day or 3 or more or even no high tides per day (because of the response of the local area to the tidal forcing; governed by the bottom topography, coastline shape, etc). \n\nThere are high tides that are extra high because the sun and the moon line up (spring tides) and high tides that are not so high because the sun and the moon are at right angles, not working together (neap tides). There are ultra high tides when the moon is especially close (proxigean spring tides). There are effects of the other planets like Jupiter   and Mars in the tides. And so on.

try surfrider.com   they may have a link on that site to check out the tide levels/times.

The short answer is, the high and low tides do not happen at the same time everywhere. High and low tides are like waves that travel around the planet. \n\nThe moon is responsible for about 2/3 of the tide, and the sun is responsible for about 1/3 of the tide. There are also effects from the other planets and celestial bodies, but since they are further away and/or smaller, the effects are much less. \n\nThe tides are caused because on one side of the earth, the gravitational pull of the moon (and other bodies) pulls the water away from the earth, and makes a big lump we call a high tide. On the other side of the earth, the earth gets pulled away from the water, leaving another big lump, a slightly smaller high tide. In between, it is low tide. That is why in most places we see 2 tides a day (although in some places there are no tides, or 1 tide a day, or more than 2 a day). \n\nThere are tides in the atmosphere too, and in the ground, as you might expect. It is not just in the water, but we can see the water tides easiest in the oceans and some big lakes.

Depends on where you are. If you live near a body of water, the wind shifts from day to night because of the nature of wind. Air will move from higher pressure to lower, and in the day, the water is colder than the land, so the wind will run to the water. In the night, the water is warmer than the land, so the wind will rush inland. In general, I'd say in the morning, because the sun's rays would heat things up faster, causing higher air pressure, and resulting in wind flow.

Tides are periodic rises and falls of large bodies of water. Tides are caused by the gravitational interaction between the Earth and the Moon. The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon. Another bulge occurs on the opposite side, since the Earth is also being pulled toward the moon (and away from the water on the far side). Since the earth is rotating while this is happening, two tides occur each day. \n\nIsaac Newton (1642 -1727) was the first person to explain tides scientifically. His explanation of the tides (and many other phenomena) was published in 1686, in the second volume of the Principia.

if you check the tide tables printed for your area on the earth you will notice significant differences in the tides all year long. There are 2 lows and 2 highs per day every day, approximately ever 6 hours, alternating high, low, high low. The tide table lists these 4 for you. The lowest lows-highs are known to be during the NEW MOON, esp during winter, but full moons are quite low-high too. So, yes, the moon does exert gravitational pull on the earth and its waters.  \n\nFull moon even affects birth rate (labor), moods, crime. Eclipses are also notorious for its effects on people as well.\n\nTide changes vary from place to place on the earth.  Even a few miles north or south of the site a tide table is made for can affect the results predicted in the little tide booklet. The topography-geology of the bodies of water all over the world also affect this. Some places on the earth go thru MAJOR changes with the tides during these full and new moon phases every day.....Bay of Fundy is one place to look up......tidal change can by 30 feet. If there is a storm, then there is possiblity of even greater tide changes given in the tide tables.

you might want to be more specific with your question, but it sounds like you're referring to the Red Tide.

Mean sea level is a average of all stages of a tide at a particular location.  There are many stages of tide; mean higher high, mean high springs, mean high water, mean high water neaps, mean lower low water, mean low water.  Mean lower water is the datum for nautical charts.  Local tides vary due to local geographic formations and lunar effects.  \n\nThe moon does not affect the water level of lakes since the amount of water is fixed.  Large lakes usually have high volume free flowing sources of water that may add or substract a noticeable quantity which may influenced by the moon.

in Alaska there are some very high tides. Turnagain Arm is famous for it's high tide and incredible tidal bore. The other that I am aware of is of course the Bay Of Fundy, NewBrunswick, Canada.

Tides happen in the atmosphere, and even in the ground itself. We can easily measure them with instruments. The solid earth tide is actually quite substantial, but it is still small enough and slow enough that we do not notice it usually. \n\nThere are definitely tides in lakes and in rivers too. Why would there not be ? \n\nIt should be noted that the tides are NOT because the water is attracted to the sun and moon. Tides are because the gravity field from extraterrestrial bodies (including other planets, not just the sun and the moon) is not constant. On one side of the earth, the force on the water is greater than it is on the earth, so the water gets pulled away from the earth. On the other side of the earth, the force on the water is less than it is on the earth, so the water gets left behind in a pile as the earth gets pulled away from the water. \n\nThis is why there are usually 2 tides per day, although it should also be noted that due to resonance effects, there are places with no tides, places with 1 tide per day, and places with more than 2 tides per day.

The level of the water actually goes up in other places when the water level goes down at your house.  This is what causes the tide to go out.

Tide refers to the water level present in the ocean. It increases depending upon the season such as winter, summer and tropical. These tides levels are categorically watched by meterological dept inorder to protect the seashore areas in lieu of natural calmities such as tsunammi, typhoons etc.\n\nIn terms of shipping, tides are always watched by the captain inorder to move the ship safely saling to avoid grounding in mud.
