The ocean's way of reminding beachfront property it's technically renting.
means The point when the rising sea reaches its highest level on the shore before turning back, pulled by the gravity of the moon and sun.
from Straightforward Old English stock: 'tide' is from 'tīd,' which simply meant 'time' or 'a point in time' (you still hear the ghost of that sense in words like 'Yuletide' and 'eventide'). Sailors and shore-dwellers needed a word for the sea's regular comings and goings, and since those comings and goings happened on a schedule, 'tide' — time itself — got borrowed to name them. 'High' just does its plain job, marking the peak of that cycle.
