Next king-tide window
- 23 Dec 2026 through 24 Dec 2026. Peak 11.35 ft on the station datum at 24 Dec 2026, 08:29 local time (NOAA lst/ldt), 1.83 ft above MHHW.
- 1 Aug 2027. Peak 11.34 ft on the station datum at 1 Aug 2027, 21:02 local time (NOAA lst/ldt), 1.82 ft above MHHW.
Prediction span stored from NOAA: 27 Sep 2026 through 28 Sep 2027. Datum STND, feet.
A king-tide window is a run of days when the NOAA predicted high is within 0.10 ft of the highest predicted high in the stored span (the next 366 days). The band only groups those highs. It is not a NOAA flood threshold and not a forecast that a street will flood.
High-tide flooding
NOAA's annual outlook for meteorological year 2026 projects 11 to 15 minor high-tide flood days at this station. That range is the published projection minus one standard deviation through plus one standard deviation. Calculated 24 Jun 2026. Method: Quadratic with ENSO Sensitivity.
The peak predicted high in the next window is 11.35 ft on the station datum. NOAA's NOS minor flood threshold is 11.38 ft on the station datum (1.86 ft above MHHW). The predicted high is below that threshold. A tide prediction is not the water level on the day.
High-tide flooding in this outlook means days NOAA projects will reach the NOS minor flood threshold at the station. NOAA does not name streets, neighborhoods, or a depth on land in the products we store. We do not add any.
