During the moon's quarter phases the sun and moon work at right angles, causing the bulges to cancel each other. The result is a smaller difference between high and low tides and is known as a neap tide. Neap tides are especially weak tides. They occur when the gravitational forces of the Moon and the Sun are perpendicular to one another (with respect to the Earth). Neap tides occur during quarter moons.

Neap tides are the less than average tides that occur during the first and third quarters of the moon.

Neap tides are when the rise and fall is at it's smallest. Spring tides are the opposite, with the highest high and a lowest low. Tidal current speeds increase accordingly with spring tides.

They are caused by the conjunctions of nearby gravitational bodies, mainly the sun and moon. If those act in unison it is a spring tide. Sun and moon at 90 degrees gives a neap. Sun and moon in the same azimuth/position gives the highest spring, when opposite also gives a spring because the earth is round so both 'pull' on the same axis, giving two bulges and dips (high & low tide).

There is a cycle between spring and neap tides of around two weeks. 'Equinoxial' springs are the highest (spring and autumn) which is where the term came from.

During the first quarter of the moon the moon and sun appear to be

at a 90 degree angle.At this time the sun's tidal influence cancels the moon's.

The tide then has a minimum range. I used to call them wimpy tides.

Neap tides are the tides that occur when the moon's phase is first quarter or third quarter. Since the sun, earth and moon form a 90° angle at those times, the sun reduces the moon's effect on the tides, so the difference between low tide and high tide is lowest during neap tide. The opposite of neap tide is spring tide (the name has nothing to do with the season), which happens when the moon's phase is full or new. The difference between low tide and high tide is greatest during spring tide due to the sun and moon working together on the tides.

A tide that occurs when the difference between high and low tide is least; the lowest level of high tide. Neap tide comes twice a month, in the first and third quarters of the moon.

A neap tide is when the moon is 90 degrees left or right to the Sun and they are both causing conflict on which gravitational force is stronger.
