Tides- How do they work?

High tide will be expressed as a positive number, which indicates how high above the average low water mark the tide will be at its greatest height. A high tide of 7.0, for example, means that at its highest, the water will be 7 feet above the average low water mark.


Low tide will be expressed as a small number, sometimes a negative number. This number indicates the relationship between the water depth at its lowest ebb and the average low water mark. A low tide of 1.5 means the lowest tide will be 1.5 feet above the average low water mark.

 

Negative low tides are known as “minus tides” and are typically shown in red font as a negative number. A minus tide of -1 means the low tide will be one foot below the average low water mark.)
