When the Moon is in its first quarter and third quarter phases, the gravitational forces of the Sun and the Moon pull at 90 degree angles from one another. This means that when the Moon is in its first quarter and third quarter phases, —

• high tides are at their lowest levels.

• high tides are experienced worldwide at the same time.

• low tides are experienced worldwide at the same time.

• low tides are at their lowest levels.
