Another type of tide, the neap tide, occurs twice per month. However, this tide type occurs when the Moon's and Sun's gravitational forces form a 90-degree angle with respect to the Earth. Neap tides happen during the first and third quarter moons.

When the gravitational pull of the moon and Sun are at right angles to each other, the daily tidal variations on the Earth are at their least (Figure 8r-3). These events are called neap tides and they occur during the first and last quarter of the moon. Figure 8r-3: Forces involved in the formation of a neap tide.
