Unusual tides here
We flag a predicted high at or above 5.2 ft MLLW (0.5 m above mean higher high water (MHHW), NOAA's national proxy for minor high-tide flooding, because NOAA lists no station threshold). We flag a predicted low at or below −1.0 ft MLLW. Mean higher high water is 3.6 ft.
No predicted tide in the next few days crosses either line.
Official sources
Predictions are astronomical tides. Wind and pressure can move the real water level a foot or more. NOAA's sensor here read 4.0 ft at 4:42 PM.
