How often do high tides occur during full and new moons?

High tides are influenced by the gravitational forces exerted by the moon and the sun, which reach their peak during the full and new moons. During these lunar phases, the alignment of the Earth, moon, and sun creates stronger tidal forces, leading to the phenomenon known as spring tides.

High tides occur approximately twice during each lunar cycle, about every 29.5 days, with notable high tides coinciding with both the full moon and the new moon. This means that there are typically two occasions—one at the full moon and one at the new moon—each month when high tides are particularly pronounced.

The timing of these high tides is a direct result of the lunar calendar, reinforcing that high tides are indeed experienced about twice each month in relation to the full and new moons. The concept of a lunar cycle is essential in understanding tidal patterns and their correlation with the moon's phases.
