Plymouth is semidiurnal — paired highs (9.9 and 11.1 ft today) and paired lows of similar size. This is a big-tide station: an average swing this week moves 10.1 ft, so the water line, current and structure change dramatically through a single cycle. A 11.5 ft swing — Plymouth's biggest this table — runs from the 11:45 PM high on Thu Sep 10 into the next low. Plymouth tops out at 11.1 ft (Thu Sep 10 11:45 PM) and bottoms at -0.4 ft (Fri Sep 11 6:03 AM).
