Can there be 4 tides a day?
This can cause higher vertical displacements, and at some places 1 , 3 or 4 tides a day instead of 2. The Earth's diameter relative to the Earth-Moon separation viz 12000 km : 380 000 km. (Therefore stronger tide producing effect [2.2x more effective than the Sun] in spite of its much weaker gravitational pull.)

Why are there so many tides?
The moon's gravitational pull on the Earth and the Earth's rotational force are the two main factors that cause high and low tides. The side of the Earth closest to the Moon experiences the Moon's pull the strongest, and this causes the seas to rise, creating high tides.
Why are the tides so high right now 2021?
Tides will increase leading up to and after the June 21 summer solstice, due to the position of the sun relative to the earth's equator. Mean sea level is typically higher in the late spring due to changing weather patterns and increasing water temperatures.

This is because the moon orbits the Earth in the same direction that the Earth rotates on its axis.
Why are the tides so big in England?
As the Earth rotates on its axis, the changing gravitational pull from the Moon powers two giant waves flowing around the coast of Britain.
