tidal day

Every tidal day (just over 24 hours) the bay experiences two flood and two ebb tides.

Also called tidal day.

Tides in Puget Sound are of the mixed type with two high and two low tides each tidal day.

Also, the difference in speed between the two flood tidal currents, or the two ebb currents of each tidal day.

Mean diurnal high water inequality and mean diurnal low water inequality are half the average differences between the two high waters and the two low waters respectively, of each tidal day over a 19 year period (see epoch).
