Detailed explanation-1: -Spring tides occur on full moon and new moon when the Sun, the Moon and the Earth are in straight line. Neap tides, on the other hand, occur when the Sun and the Moon are at right angle to each other.
Detailed explanation-2: -When the sun, moon and Earth are all lined up, the sun’s tidal force works with the moon’s tidal force. The combined pull can cause the highest and lowest tides, called spring tides. Spring tides happen whenever there is a new moon or a full moon and have nothing to do with the season of spring.
Detailed explanation-3: -When the sun, moon and the earth line up in a straight line, the gravitational forces of the moon and the sun combine to pull the water on the earth much more than just the moon pulling the water alone. This kind of a tide is called a spring tide.
