MLWS (Mean Low Water Springs)
Return To Index
MLWS (Mean Low Water Springs), is a tidal term used in navigation and nautical charts to describe the average height of the low waters that occur during the spring tides (the tides with the greatest range, happening every fortnight near new or full moon) over a long period, typically 19 years.
Key Details about MLWS:
Definition: It is the average height of two successive low waters during the 24-hour period of spring tides.
Context: It is one of the various chart datums used to determine the low-water reference level for nautical charts.
Significance: MLWS gives a good indication of the lowest level of the water surface under normal weather conditions, making it crucial for determining safe depths for anchoring or navigating, particularly in shallow areas.
