The highest spring tides (equinoctial springs) occur at the equinoxes.
How do spring tides affect the tides?
During spring tides, since the Moon and the Sun are aligned, they exert gravitational force on the tides at the same time and in the same direction. However, when the Sun and Moon are at right angles to each other during quarter moons, the forces of gravity partially cancel each other out.
