When the Moon waxes, high tide is about 5 hours prior to low; when it wanes, high tide is some 7 hours prior to low; this figure is adjusted by three factors: the age of the moon, its distance from the earth, & the strike of the coastline or other geographic features. Also, the actual time is dependent upon the time of meridian transit.: M+ 4sine( angle between Sun & Moon), if waxing before First Quarter, or waning before the Last Quarter,, this is the low tide, five hours earlier is the high; if waning before the Last Quarter or waxing before the First Quarter, subtract five hours from the result to get the High tide, then add 7 hours to the High to get Low. The adjustment for moon's distance is at most 58 minutes; coastal strike is one hour for every 15 degrees from true north. This will not give an exact result, but it will be close enough.

∙ 8y agoThe gravity of the Moon and Sun cause 'bulges' of water on either side of the Earth. As the Earth turns on its axis, any given place will pass under a bulge roughly twice a day. It's not exactly 12 hours, because in the time between one high tide and the next, the Moon has moved a little in its orbit.http://scijinks.jpl.NASA.gov/tides/

∙ 8y agoWe get two high and low tides because the Earth rotates through the places where the Sun's and Moon's gravity cause the water to be deep and shallow.

How many high and low tides occur in one day?
6. There are 12 hours between high tides and low tides occur "exactly" halfway between them.
Does high tides and low tides happen every day?
No, not at all. Tides are caused by the gravitational pull of the moon and the sun on the earth's waters. The earth rotates once every 24 hours and the earth/moon system rotates roughly once every 27 days. The complex interaction between the two creates a pattern that repeats roughly every 24 hours and 50 minutes. In other words, the whole pattern of high and low tides shifts by a bit under an hour every day. But there's still more: Within that pattern there oscillations that produce two different high and two different low tides every day, so there's about 6 hours and 12 minutes between any pair of high and low tides.
How many low tides happen at a given coast in any 24-hour period?
Up to 2 low-tides. It depends upon the alignment of the Sun and the Moon, the tides, the state of the ocean and the shape of the coastline. Some areas are semi-diurnal, with two high tides and two low tides. Other areas can receive a mixed tide, which is one low tide and one high tide per day.
How regularly do tides change?
There are generally two high and two low tides during each 24 hour period, so there would "usually" be four changes per day.There are two low, and two high tides every Lunar day. A lunar day is the time it takes a fixed spot on the earth to rotate from beneath the moon, and to reach the moon again.
How fast tides come in and go out?
While local geographic conditions can make for unique situations, in general there are two high tides and two low tides each day, space roughly six hours apart. So if there's a high tide at noon, there will be a low tide at 6PM, high tide at midnight, and low tide again at 6AM. I said roughly because the moon is moving around the earth once every 28 days, so the high and low tides time move, on average, a bit under an hour each day.
Why are there usually two high tides and two low tides eachday?
Each tides last 6 hour.
How many high happen at a given coast in any 24 hour period?
The high tides change approximately after every 12 hours depending with the season.
How many high tides happen at a given coast in an 24 hour period?
Only2 high tides happen a day

Do tides occur the same time every day?
No, not at all. Tides are caused by the gravitational pull of the moon and the sun on the earth's waters. The earth rotates once every 24 hours and the earth/moon system rotates roughly once every 27 days. The complex interaction between the two creates a pattern that repeats roughly every 24 hours and 50 minutes.

What causes the earth is have tides?
The cause of Earth's tides is gravitational pull from the Moon and the Sun. The Moon's influence on the tide is far, far, stronger than the Sun's, however. The gravity pulls up on the water on the part of the Earth closest to the Moon, as well as causing a bulge on the exact opposite part of the bulge. As the Earth rotates, the location of high tide moves around the world. In every 24 hour cycle, or every full rotation of Earth, there are two high tides and two low tides.

How many high tides happen at a given coast in any 24 hour period?
Two highs and two lows in 24 hours and about 52 minutes, on the average.Depending on local conditions, most places experience two high and one low or two low and one high tide in a 24 hour period.
