- High water lunitidal interval. The high water lunitidal interval (or high water interval) is the time interval between the moon’s transit and the next high water.
- Mean lunitidal interval.
- Interval (hrs) = M2 phase (degrees) x M2 period (hrs) / 360 (degrees)
- Please note:

The right hand side of the clock is marked “hours until low tide” and has a count-down of hours from 5 to 1. The number pointed to by the hand gives the time “until” the (lunar) low tide.
How do you calculate high tide time?
The rule of twelfths works like this; take the difference in height between the high and low tide on that day, and divide that by 12 equal chunks.
