Seattle runs mixed-semidiurnal water: two highs and two lows daily, unequal by ~2.6 ft between successive highs this week. This is a big-tide station: an average swing this week moves 7.3 ft, so the water line, current and structure change dramatically through a single cycle. A 13.6 ft swing — Seattle's biggest this table — runs from the 2:59 AM low on Sat Oct 31 into the next high. Seattle tops out at 11.7 ft (Thu Nov 5 1:56 PM) and bottoms at -2.0 ft (Sat Oct 31 2:59 AM).
