Plymouth is semidiurnal — paired highs (8.7 ft today) and paired lows of similar size. This is a big-tide station: an average swing this week moves 8.9 ft, so the water line, current and structure change dramatically through a single cycle. A 9.8 ft swing — Plymouth's biggest this table — runs from the 1:39 AM high on Sat Aug 1 into the next low. Plymouth tops out at 10.5 ft (Thu Aug 6 6:01 PM) and bottoms at 0.5 ft (Sat Aug 1 8:12 AM).
