The amount of tides in a day is 2 tides per day.
Although in reality in a 24 hour day period there are in total of 4 tides which are 2 high tides and 2 low tides.
Because the earth rotates through two tidal “bulges” every lunar day, we experience 2 high and 2 low tides every 24 hours and 50 minutes.
The different types of tides include.
Diurnal Tide.
A diurnal tide has one episode of high water and one episode of low water each day.
Semi-diurnal Tide.
A semi-diurnal tide has two episodes of equal high water and two episodes of low equal water each day.
Mixed Tide.
Meteorological Tide.
The first of them is the value awarded to the height of the tide and is the one reflected in the tide tables.
The second is the lunar phase and is directly related to the average activity of fish in the solunar charts.
High tides and low tides are caused by the moon.
The moon's gravitational pull generates something called the tidal force.
The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon.
These bulges of water are high tides.
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun, and the rotation of the Earth.
Tide tables can be used for any given locale to find the predicted times and amplitude.
