The minor periods start with the soaring and placing with the moon and its period is somewhere around one hour.
Tide movement information is mostly witnessed on nautical charts, offered being a table of circulation speeds and bearings at hourly intervals, with independent tables for spring and neap tides.

An extra complication for Prepare dinner Strait's movement pattern is that the tide on the north aspect (e.g. at Nelson) follows the common bi-weekly spring–neap tide cycle (as uncovered along the west facet from the place), even so the south side's tidal pattern has just one cycle monthly, as on the east aspect: Wellington, and Napier.
