Seattle Tide Chart: Widest Difference Between Two Daily Low-to-High Rises
The answer
In NOAA's 30-day Seattle, Washington sequence, 2026-11-28 has the widest difference between its two listed low-to-high rises: 13.33 ft (4.064 m). The first change is 15.61 ft and the second is 2.28 ft.
How it was calculated
This analysis compares the two same-pattern, consecutive tide changes that NOAA lists on each station-local date.
It uses only NOAA's published turning points and does not interpolate an unlisted tide height or time.
This is a planning aid from predictions, not observed water levels or a safety forecast.
