SPRING AND NEAP CYCLE

Cycle dates near Seattle, WA

Next spring tide on Sun 03 May (range 3.9m / 12.6ft). Last neap on Sun 26 Apr. Next neap on Fri 08 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

EDITORIAL

About tides at Seattle, WA

Seattle sits on Elliott Bay, where Puget Sound's inland-sea tide reaches the city after rolling in from the Strait of Juan de Fuca. The gauge is at Pier 36, and the tide signature here is a textbook example of an amplified mixed semidiurnal pattern — mean range about 2.3 metres, with the daily lower low and higher high often three metres or more apart. The pattern is two highs and two lows of unequal size each day, and the asymmetry is sharp: the morning low and the evening low can differ by a metre, and the same for the highs. That changes the day for anyone walking the waterfront, kayaking out of Alki, or watching boats lock through Ballard. The lowest lows of the month — clustering around new and full moons, especially in summer afternoons — pull water off the inner-shelf flats at Lincoln Park and Discovery Park, opening the rocky intertidal for hours. Predictions on this page come from NOAA CO-OPS station 9447130. Pacific storm systems in winter can lift water levels 20–30 cm above predicted, and a strong south wind down the Sound can add to that on top of spring tide.

COMMON QUESTIONS

Tide questions about Seattle, WA

When is the next high tide at Seattle?

The hero block shows the next high tide at the Pier 36 gauge in local Pacific time, height above MLLW. The 7-day table breaks out all daily extremes — note that Puget Sound's mixed semidiurnal pattern produces a sharp asymmetry, with the lower low often more than a metre below the higher low in summer.

Why is the tide range so big at Seattle?

Puget Sound is a long, deep inland sea connected to the Pacific via the Strait of Juan de Fuca. The tidal wave that enters the strait amplifies as it propagates inland, so the range at Seattle (about 2.3 metres mean) is roughly twice what you'd see on the open Washington coast. Olympia at the head of the Sound runs higher still.

When are the best lowest-tide windows for shoreline exploring?

Seattle's lowest-low tides cluster around new and full moons, with the biggest summer-afternoon lows at Discovery Park, Lincoln Park, and the West Seattle shoreline. The lower of the two daily lows is what to watch — when it falls below 0 metres MLLW, intertidal shelf opens up that's covered the rest of the month. The 7-day table on this page flags each day's lowest predicted tide.

Where do these tide predictions come from?

NOAA CO-OPS station 9447130, Seattle (Pier 36). NOAA's harmonic predictions for Puget Sound stations are calibrated against decades of gauge data at each location. Accuracy is high under normal weather; storm surge and strong wind setup down the Sound can shift actual water level by 20–30 cm or more.

Is this safe to use for navigation?

No. For piloting in Puget Sound use NOAA's authoritative tide and current products and USCG notices. Currents at the Tacoma Narrows, Deception Pass, and Agate Pass are some of the strongest in the lower 48 — those are real-time navigational decisions, not tide-table decisions.
