King Tides Washington 2026 & 2027: Dates for Seattle, Port Townsend and La Push — and Where the Lows Go

Published · 7 min read · every number computed from NOAA predictions

Washington's king tides for the 2026-27 season peak twice: Christmas week, December 23-28, 2026, at La Push and Port Townsend, and January 24-26, 2027 in Seattle. Per NOAA predictions the state's highest high is 13.09 ft MLLW at Seattle (station 9447130) on Monday, January 25 at 7:16 AM. The deepest low you can see in daylight belongs to the outer coast: -1.97 ft at La Push (9442396) on December 23 at dusk.

What makes a tide "king"

Nothing official. NOAA's definition: "A King Tide is a non-scientific term people often use to describe exceptionally high tides." The mechanism behind the biggest ones is a perigean spring tide — in NOAA's words, one that "occurs when the moon is either new or full and closest to Earth." That lineup is not rare: "Typically between 6-8 times each year, the new or full moon coincides closely in time with the perigee of the moon." During any spring tide, "high tides are higher and low tides are lower than average" — the swing works both ways, which is why this page has two halves: the highs people photograph, and the question of whether the matching lows are worth anything.

The same season at all twelve stations we compute is in King Tides 2026 & 2027 Dates. This page is Washington only, and Washington needs its own page because the two halves come apart here in a way they don't in Oregon.

The Washington king tide dates: the season's highest highs

The Christmas run carries the coast and the northern Sound; Seattle's peak waits for late January. Notice the clocks as much as the heights: Puget Sound's biggest highs arrive with morning coffee, between 5:49 and 8:22 AM, while La Push crests near midday — much friendlier light for a photograph.

Station (NOAA id) Highest predicted high Date Time of high Next highest
Seattle (9447130) 13.09 ft Mon, Jan 25, 2027 7:16 AM 13.04 ft Jan 24 · 13.01 ft Dec 26 · 13.00 ft Jan 26 · 13.00 ft Dec 27
Port Townsend (9444900) 9.96 ft Sat, Dec 26, 2026 7:08 AM 9.95 ft Dec 25 · 9.91 ft Dec 27 · 9.83 ft Dec 28 · 9.81 ft Dec 24
La Push (9442396) 11.01 ft Thu, Dec 24, 2026 11:43 AM 10.91 ft Dec 25 · 10.85 ft Dec 23 · 10.79 ft Nov 25 · 10.78 ft Jan 22

Each station's five highest predicted highs of the October 2026 – March 2027 season. Computed 2026-09-04 from NOAA predictions, heights in ft MLLW, times local. Predictions are astronomical forecasts, not observations: a winter low-pressure system or a strong onshore wind can push the actual water level well above these numbers — which is exactly what the photos are for.

Those photos are the point of the Washington King Tides Program, a citizen-science project run by Washington Sea Grant (part of the University of Washington's College of the Environment). Participants photograph waterfront locations in their communities during king tides — ideally spots whose ordinary high tide they know — so the images document where a future, higher sea might reach. Photos go in through the MyCoast website or app. When this page was written on September 4, 2026, the program page had not yet posted 2026-27 photo dates; the NOAA-predicted highs above are the days to watch for.

The honest half: Puget Sound's deep lows are at night

In Oregon, the king-tide highs drain to the season's deepest daylight lows the same afternoon. In Puget Sound they don't. At Seattle (9447130), November and December 2026 have zero daylight low-tide windows — 21 lows below +1.0 ft each month, every one of them after dark. Port Townsend (9444900) is the same: 22 sub-+1.0 ft lows in each of those months, none with usable light.

It isn't that winter water is shallow here; it's that the deep lows and the daylight stop overlapping. Seattle's five deepest daylight lows of the entire king season all crowd into February and March 2027, and the deepest is just -0.65 ft (Thursday, March 25 at 1:45 PM). Compare July: on July 14, 2026, Seattle's daylight low reached -3.80 ft at 11:20 AM — over three feet more reef than anything the king season will show you before sunset. If you tidepool on Puget Sound, king tide season is spectator season, and your dates are in summer. The Puget Sound low tide calendar has the full year's picture.

Station Deepest daylight low, Oct 2026 – Mar 2027 Date Time of low Daylight in window Score
Seattle (9447130) -0.65 ft Thu, Mar 25, 2027 1:45 PM 175 min 57 (Fair)
Port Townsend (9444900) -1.64 ft Wed, Feb 17, 2027 7:06 PM 57 min 55 (Fair)
La Push (9442396) -1.97 ft Wed, Dec 23, 2026 6:03 PM 39 min 59 (Fair)

Computed 2026-09-04 from NOAA predictions. Heights in ft MLLW, times local. Score is Tidewindow's 0-100 rating of depth, daylight and timing; the methodology page shows the formula.

Port Townsend sits between the two regimes: its -1.64 ft on February 17 is real depth, but the low itself lands at 7:06 PM and only 57 minutes of the window are lit. Its most usable king-season window is shallower — -0.77 ft on Monday, February 15, 2027 at 5:04 PM, with 158 daylight minutes, scoring 65 (Good).

The exception: La Push keeps daylight windows all winter

The outer coast never goes fully dark. While Seattle and Port Townsend post zero daylight windows in November and December, La Push keeps 6-7 a month through the winter, and its king-season lows have real depth:

Date Low (ft MLLW) Time of low Walkable window Arrive by Daylight in window Score

Tue, Dec 22, 2026 -1.45 5:15 PM 3:10 – 7:25 PM 4:15 PM 79 min 55 (Fair)

La Push's five lowest daylight lows of the season, computed 2026-09-04 from NOAA predictions for station 9442396. Same conventions as above.

Read the daylight column before the depth column. December 23 is the deepest water of the season, but only 39 of its minutes are lit; January 21 gives up 0.15 ft of depth for more than twice the light, and it is the better trip. That is the winter pattern: show up when the window opens, mid-to-late afternoon, and work the falling tide while you can still see — don't wait for the low itself. No window in these tables reaches the Great band; Washington's king season is played in the Fair-to-Good range, in the last hours of light.

Winter lows come with winter ocean, and the outer coast is the most exposed shore in the state. Predictions are not observations, and swell can erase a calm-water window entirely; what a sneaker wave is, and what the official agencies say about it, is in What is a sneaker wave?.

Where to stand

How to keep these dates

They are months away, which is how they get lost. The Tide Window Finder lists every upcoming daylight window at all three Washington stations with its arrive-by time, and takes a ZIP code to pick the nearest station (the lookup runs in your browser; nothing is sent). The Trip Picker will chain the December 22-23 and January 21-22 La Push windows into a best consecutive-days answer if your travel dates are flexible. And the station picker at the end of this page hands you a calendar feed that puts every Good-or-better daylight window in your calendar app with an arrive-by alarm — subscribe once, and the whole season above is inside its range.

Quick answers

When are the king tides in Washington in 2026 and 2027?

Per NOAA predictions at the three Washington stations Tidewindow computes, the highest highs of the October-to-March season come in two runs: Christmas week (December 23-28, 2026) at La Push and Port Townsend, and January 24-26, 2027 at Seattle. The single highest is 13.09 ft MLLW at Seattle (station 9447130) on Monday, January 25, 2027 at 7:16 AM; La Push (9442396) peaks at 11.01 ft on Thursday, December 24, 2026 at 11:43 AM.

Can you go tide pooling during Washington's king tides?

Mostly no — and that is the honest difference between Washington and Oregon. At Seattle and Port Townsend, November and December 2026 have zero daylight low-tide windows: 21-22 lows below +1.0 ft each month, every one of them after dark. The exception is La Push on the outer coast, which keeps 6-7 daylight windows a month through winter, with lows near -2.0 ft at dusk. Puget Sound's deep daylight lows come back in summer.

What is the deepest daylight low of Washington's 2026-27 king tide season?

-1.97 ft MLLW at La Push (station 9442396) on Wednesday, December 23, 2026 at 6:03 PM — but only 39 minutes of its window are in daylight. The most usable deep window is La Push on Thursday, January 21, 2027: -1.82 ft at 5:50 PM with 82 daylight minutes, scoring 63 (Good). For comparison, Seattle's deepest daylight low of the whole season is just -0.65 ft, on March 25, 2027.

What is the Washington King Tides Program?

A citizen-science project run by Washington Sea Grant, part of the University of Washington's College of the Environment. Participants photograph waterfront locations during king tides to document where future, higher sea levels may reach, and submit the photos through the MyCoast website or app. As of September 4, 2026 the program had not yet posted its 2026-27 photo dates; the NOAA-predicted highs on this page are the dates to watch.
