Spring Tides occur during two phases, full and new moon. This is because the moon earth and sun are aligned during both of these phases. It is opposite during neap tide, in whâ¦ich the moon and sun meet at a right angle on earth, which means the moon during neap tide is at the first or third (last) quarter phase.
A spring tide is a common historical term that has nothing to do with the season of spring. Rather, the term is derived from the concept of the tide springing forth.. Spring tides occur twice each lunar month all year long without regard to the season. Neap tides, which also occur twice a month, happen when the sun and moon are at right angles to each other.
