About Brant Rock, Green Harbor River tides
Brant Rock, Green Harbor River is a NOAA harmonic tide station (8446009): its predictions come from the tidal constituents NOAA derived from water levels measured at this spot. Heights are in feet above MLLW (Mean Lower Low Water), the datum of US nautical charts, so they line up with charted depths.
In the next 30 days, Brant Rock, Green Harbor River has two highs and two lows on 26 days and three turns on 4 days, and the daily range runs from 6.3 to 12.8 ft. That is a semidiurnal tide: two highs and two lows a day, each pair close in height.
Use the curve above to time a harbor entrance, a beach walk, fishing a moving tide or clearing a shallow bar, and remember that wind, air pressure and river flow can push the real water level above or below the prediction. The daily tidal range in the tables shows how much water moves each day: bigger ranges around the new and full moon mean stronger currents.
The latest water temperature near Brant Rock, Green Harbor River is about 55°F, from NDBC buoy 44013, 18 mi away, at 7:10 AM EDT. Water temperature shapes where fish hold and feed, and tells you what to wear in the water, so check it alongside the tide before you head out.
