Boston is semidiurnal — paired highs (8.8 ft today) and paired lows of similar size. This is a big-tide station: an average swing this week moves 9.1 ft, so the water line, current and structure change dramatically through a single cycle. A 10.0 ft swing — Boston's biggest this table — runs from the 1:32 AM high on Sat Aug 1 into the next low. Boston tops out at 10.4 ft (Thu Aug 6 5:41 PM) and bottoms at 0.2 ft (Sat Aug 1 7:49 AM).
