Together, the gravitational pull and the centrifugal force are responsible for creating the two major tidal bulges on the earth. The height of rising water (high tide) varies appreciably depending upon the position of sun and moon with respect to the earth. At depths, currents are generally slow with speeds less than 0.5 knots. However, it gets minimised by the suns force that counteracts it, When the moons orbit is nearest to the earth it is known as perigee. When the highest point of the wave, also known as the crest, reaches the coast, it is called a high tide.
