Quizplus · Accepted Answer

Spring tides occur approximately twice a month, at every full and new moon, because these are the times when the Sun, Moon, and Earth are aligned, leading to the greatest gravitational pull on the oceans. This results in the highest high tides and the lowest low tides, known as spring tides. Since there are roughly 12 full moons and 12 new moons each year, this leads to about 24 to 26 spring tides annually, depending on the lunar cycle.
