A spring tide refers to the 'springing forth' of the tide during new and full moon. 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.
From the highest level to the lowest: 1  Highest Astronomical Tide (HAT) â The highest tide which can be predicted to occur. 2  Mean High Water Springs (MHWS) â The average of the two high tides on the days of spring tides. 3  Mean High Water Neaps (MHWN) â The average of the two high tides on the days of neap tides.
