King tide dates are set by the moon. The new and full moons that fall nearest the moon’s closest approach to Earth bring the biggest predicted tides, so the same few dates recur from coast to coast. Across all 179 stations the peak dates shared most widely this season are November 25, 2026 (113 stations), December 24, 2026 (71 stations) and October 27, 2026 (56 stations).

The calendar

King tide dates by coast, October 2026 to March 2027

Each row is a run of dates on which a coast’s NOAA stations reach the highest predicted tides of their season. The station count says how many of the coast’s stations have a king tide window peaking on those dates. The highest column names the station whose peak stands furthest above its own mean higher high water, with the predicted height and time. Every figure traces to a NOAA prediction row and to the station’s published datums, and each station page lists all of its windows with the moon phase and the live National Weather Service product for its zone.

The heights are NOAA’s predictions of the astronomical tide. Wind, barometric pressure and river flow raise or lower the real water level on the day, and the National Weather Service’s coastal flood product for the zone is the authority on whether water is expected over land.

Every station

How far above normal each station’s season peak reaches

One dot per NOAA harmonic station, coloured by how far its highest predicted tide of the season stands above mean higher high water at that station. The darkest dots this season sit in Alaska (Homer, +4.2 ft) and, in the lower 48, at Eastport, ME (+2.5 ft). Hover or tap a dot for the station’s season high and first window; click it for the tide chart.

Size

Season October 2026 to March 2027. Each dot is one NOAA harmonic prediction station, coloured by how far its highest predicted tide of the season stands above mean higher high water (MHHW), the average of each day’s higher high tide at that station. Measuring against MHHW compares each station with its own ordinary high, so 2 ft above MHHW means the same thing in Alaska and in Florida even though their tide ranges differ tenfold. Heights are NOAA’s astronomical predictions; the National Weather Service issues the coastal flood products for each zone, and every station page shows them live.

The term

What a king tide is

NOAA’s National Ocean Service: “A King Tide is a non-scientific term people often use to describe exceptionally high tides.” It adds that “Higher than normal tides typically occur during a new or full moon and when the Moon is at its perigee, or during specific seasons around the country.” Perigee is the moon’s closest approach to Earth in its monthly orbit; when it lines up with a new or full moon, the sun and moon pull together on a moon that is also nearer than usual, and every coast gets the biggest predicted tides of its year.

On these pages a king tide is the highest predicted tide NOAA publishes for a station from October 1, 2026 to March 31, 2027. Each station gets up to three windows: the season’s highest predicted high, extended to the consecutive days whose highest tide stays within 0.3 ft of it, then the next highest outside that run, then the next. The dates cluster on the full moons of late October, late November, late December and late January this season, and the calendar above shows which of those each coast shares.

Tidal flooding in Miami during the October 2016 king tides, when exceptionally high astronomical tides met rain and onshore wind. The prediction is the tide; the weather is what put the water this deep. “Miami tidal flooding with rain at high tide during king tides 02” — B137 — CC0

Sunny day tidal flooding on a street in Miami’s Edgewater district at the morning high tide on October 17, 2016, during that autumn’s king tides. No rain and no storm: the predicted tide alone put water in the road, which is what a peak well above MHHW looks like on a low shoreline. “Edgewater 23 Street tidal flooding October 17 2016 morning high tide 11” by B137, CC0

How to read the numbers

Feet above MLLW. NOAA measures every tide prediction from mean lower low water, the long term average of the lower of each day’s two lows, which is also the zero on NOAA’s nautical charts. A 7.2 ft king tide at San Francisco means the water stands 7.2 feet above that average lowest level.

Above MHHW. Mean higher high water is the long term average of the higher of each day’s two highs at a station. A peak 1.4 ft above MHHW is 1.4 feet higher than an ordinary day’s higher high tide there, which is the number to look at when comparing stations: a 12 ft tide is an ordinary afternoon at Eastport, Maine and a rare event at Galveston, but 2 ft above MHHW means the same thing at both.

The window. The highest predicted tide of the season, plus the consecutive days around it whose highest tide stays within 0.3 ft. The peak date and time are the single highest prediction inside it, in station local time, and the moon column is the phase at that instant.

The NWS line. Every state and station page checks the National Weather Service for a Coastal Flood Advisory, Watch, Warning or Statement covering the station’s public forecast zone and shows the product by name, with a link, when one is active. The prediction says how high the astronomical tide reaches; the product says what NWS expects the water to do over land on the day.

A full moon over the sea at Coruripe, Brazil; the physics is the same on every coast. Full and new moons bring the spring tides, and the ones that fall nearest the moon’s perigee bring the king tides, which is why the moon column beside each peak reads Full Moon or New Moon so often. “Full Moon Over the Sea” by Alfredo J G A Borba, CC BY-SA 4.0

King tide dates by state

Each state page lists every NOAA station on that coast with its first king tide window and its season high above MHHW, links each one to its tide chart, and shows the National Weather Service coastal flood products active for the state’s zones right now.
