Dead low tide is a term used to describe the lowest point of the low tide cycle. It is also known as the lowest ebb or the lowest tide. In some coastal regions, it is referred to as the neap tide. Other synonyms for dead low tide include the low water mark or low tide level. Some people also use the term low water spring, although this is technically incorrect as spring tides refer to the greatest difference between high and low tide rather than the actual occurrence of low tide. While these terms differ, they all refer to the same phenomenon: the minimum point of the tide cycle.
