For obvious reasons, try to time your forays with the 6-hour intervals in this diurnal tide
NSW is subject to a diurnal tide
that has a maximum range of about 1.
Several other interesting contrasts exist among regional tides, in the Gulf of St Lawrence, when the High Water of a diurnal tide coincides with one of the two High Waters of the semidiurnal tide, the Higher High Water of the day is higher than the Lower High Water, assuming that the semidiurnal tide dominates at the location.
The result is that the semidiurnal tide is scarcely noticeable in this area, and so the diurnal tide becomes dominant.
The two semidiurnal Low Waters will occur when the diurnal tide is at Mean Water Level, resulting in two Low Waters of equal height.
However, the peak of the diurnal tide would be around 9:00 hours, with HLW about 6:00 hours and HHW around noon.
In part, the salinity levels in these lakes are maintained because of changes in water level caused by variable barometric pressures responding to cycles longer than the semidiurnal and diurnal tide
In order for true diurnal tide conditions to exist, the amplitude of the diurnal tide must be two to four times larger than the semidiurnal tide, depending on the time relationship between the two.
However the diurnal tides probably will not be altered when progressing into the estuaries.
Most of us have heard of the very high tides in the Bay of Fundy where the water level changes by about 50 feet during diurnal tides
and would agree this is probably the best place in the world for tidal power.
This produces major changes in the lunar diurnal (once a day) tides, and so is important at places such as Victoria, where diurnal tides
This correlation strongly suggested a relationship between Puerto Rico seiche activity and the astronomical tides, specifically the semidiurnal tides because only they, and not the diurnal tides
, are tied to the moon's phases.
