Definition
Expressed as a set, the true direction toward which the water flows, and a drift or rate in knots. It is periodic and predictable, reversing or rotating over the tidal cycle, and is distinguished from ocean currents, which are largely non-tidal. Rates are strongest in constrictions and over headlands, and off north-west Europe can exceed 8 knots at springs in places such as the Pentland Firth.
