When do spring tides occur?

Twice a month, the tides rise to their highest point and then plummet to their lowest point. Spring tides have the greatest difference between high and low water, whereas neap tides have the smallest difference. Here we talk in detail about spring tides and When do spring tides occur?

What are Tides?
Tides are high waves of water that travel across seas surface. In other words, the rising and falling of layers of water on sea surface comprise tides. They are primarily caused by the gravitational attraction of the moon and sun on the ocean. The tides are affected by both the moon and the sun, but because the moon is considerably closer to the earth it has more than double the influence of the sun.

Spring tides
A spring tide is often known as a King Tide. The tides of spring aren't called for the season. This is spring in the sense that it has sprung forth, burst forth, and risen. So, every month, spring tides deliver the most severe high and low tides. They always happen every month around the full and new moons. Average tidal ranges are somewhat larger during full or new moons when the Earth, sun, and moon are approximately aligned. This happens twice a month. When the moon lies exactly between the Earth and the sun, it seems young (dark). When the Earth lies between the moon and the sun, the moon looks full.  The gravitational attraction of the sun is reinforced by the gravitational pull of the moon on Earth when there is a new and full moon. It causes the seas to expand a little more than usual. This indicates that high tides are higher and low tides are lower than usual. As a result, the height of high tide which is what a spring tide is rises.  Because the earth is so huge, the gravitational force on the side of the earth closest to the moon is larger than the pull on the side farthest from the moon.

When do spring tides occur?
Regardless of the season, spring tides occur twice a month throughout the year. When the sun, moon, and earth are all aligned, spring tides occur. The rising and falling of ocean tides are mostly caused by the moon and sun. It happens soon after each full and new moon. Spring tides occur 36 to 48 hours after the full or new moon, and at nearly the same time of day for any particular place, due to the regular movements of the sun, moon, and earth. Spring tides aren't all the same size. The equinoxes which are March 21 and September 21, when day and night are of equal duration throughout the planet produce significantly larger springs.  

There are two high tides and two low tides per day in many areas. Although, it is not the case everywhere. The height difference between high and low tides fluctuate as the moon fluctuates from new to full and back to new. The rising and falling of ocean tides are mostly caused by the moon and sun. The height of the tides and their change in time for any specific area on Earth's surface are influenced by the shape of a beach. It is also influenced by the angle of the shoreline leading up to your beach, a larger coastline and the surrounding ocean currents and winds.
