Seattle is semidiurnal — paired highs (9.8 and 11.3 ft today) and paired lows of similar size. This is a big-tide station: an average swing this week moves 8.5 ft, so the water line, current and structure change dramatically through a single cycle. A 12.4 ft swing — Seattle's biggest this table — runs from the 10:04 AM low on Wed Sep 9 into the next high. Seattle tops out at 11.6 ft (Fri Sep 11 6:04 PM) and bottoms at -1.0 ft (Tue Sep 8 9:12 AM).
