New York Harbor In most places in the world, tidal currents flood (come in) until high tide and then ebb (go out) until low tide. Not so in New York Tide Wheel Harbor. Depending on the location, the average tidal current lag-- the gap between high or low water and the beginning of the flood or ebb-- can be as much as two hours and 45 minutes. High Tide at the Battery Devised by boatbuilder Don Betts, the tide wheel is a simple means of gauging the tidal current lag on the waterways surround- ing Manhattan. To use it, find the time of high tide at the Battery r No for the date you’re interested in, then spin the inner ‘clock’ wheel ive rt until that time lines up with the arrow at the top of card. The outer R h n F rings tell you the direction of flow at any given time on any of o rth Floo lo s o d o Manhattan’s three ‘rivers.’ N iver Sout d R h F d The tide wheel is only an approximate guide.
