The highest tides, called spring tides, are formed when the earth, sun and moon are lined up in a row. This happens every two weeks during a new moon or full moon. Smaller tides, called neap tides, are formed when the earth, sun and moon form a right angle.
A perigean spring tide occurs when the moon is either new or full and closest to Earth. Often between 6-8 times a year, the new or full moon coincides closely in time with the perigee of the moon — the point when the moon is closest to the Earth. These occurrences are often called ‘perigean spring tides.
Why does full moon cause higher tides?
When the moon is full, it is on the opposite side of the Earth from the sun. The opposing gravitational pull of the moon and sun causes the most extreme tides of the lunar cycle, with high tides reaching about two feet higher than they do during other parts of the month .
Why are there high tides during a full moon?

Tide-generating forces are also enhanced when the moon is directly overhead at the equator, part of a cycle lasting 27.2 days Spring tides are always higher at these times of year.
What is the relationship between the Moon and tides?
High 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.
The tides are the result of the moon exerting its gravitational force on the ocean and bulging it both toward and away from the moon. The tide is higher, the ocean is higher, at the location closest to the moon and on the opposite side of the Earth. As the Earth rotates, the position relative to the moon changes, so the bulge moves.
Why does the Moon have more effect on tides?
The ocean tides on earth are caused by both the moon’s gravity and the sun’s gravity. Even though the sun is much more massive and therefore has stronger overall gravity than the moon, the moon is closer to the earth so that its gravitational gradient is stronger than that of the sun.
