Tide table

[1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal curve for the location.

However, successive (semidiurnal) tides are linked to the Moon's orbital period, thus they are approximately 24/27.3 hours later each day or about 50 minutes but many other observations and considerations are required to develop accurate tide tables.

Tide prediction was long beset by the problem of laborious calculations.
