Science Primer - diurnal tide
https://scienceprimer.com/glossary/diurnal-tide
A tidal pattern characterized by a single tidal cycle of one high tide and one low tide every day.
The orbit of the Moon drives the tidal period*. The Moon goes around the Earth once every 24 hours and 50 minutes resulting in high and low tides occurring about an hour later each day.
Diurnal tide*s are one of the three commonly described tidal patterns. The other two common tidal patterns involve two tidal cycles per day.en
