Neap Tide

When the Sun and Moon are not aligned, neap tides take place. During the moon's quarter phases the sun and moon work at right angles, causing the bulges to cancel each other. They occur when the gravitational forces of the Moon and the Sun are perpendicular to one another (with respect to the Earth), producing a smaller difference between high and low tide. Needless to say, these tides are fairly weak.
