About South Yarmouth, Bass River tides
South Yarmouth, Bass River is a NOAA subordinate station (8447504): NOAA predicts its times and heights from Boston (8443970) with offsets for this spot, so treat them as a close guide rather than an exact prediction. 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, South Yarmouth, Bass River has two highs and two lows on 26 days and three turns on 4 days, and the daily range runs from 1.9 to 3.8 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 South Yarmouth, Bass River is about 56°F, from NDBC buoy 44020, 13 mi away, at 1:00 PM 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.
