The angler tradition that rates each day for fish-bite likelihood using moon transits and rise/set. One to five stars, not a scientific forecast.

Cycle dates near Astoria (Columbia River), OR

Next spring tide on Fri 01 May (range 2.9m / 9.6ft). Last neap on Sun 26 Apr. Next neap on Sat 09 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.

About tides at Astoria (Columbia River), OR

Astoria sits on the south bank of the Columbia River near its mouth, where the second-largest river by volume in the United States meets the Pacific across one of the most dangerous bar crossings in North America. The tide gauge at the Tongue Point pier reads a complicated signal: the open-Pacific mixed-semidiurnal tide pushing inland against the river's seaward current. Mean range at Astoria is about 2.4 metres, climbing past 2.9 on spring tides. The pattern is mixed semidiurnal, two highs and two lows of unequal size each day, the bigger swing falling on the lower-low water. The Columbia Bar at the mouth — between the south jetty at Fort Stevens and the north jetty across in Washington — is the ship-traffic chokepoint, and the rip and breaking water at the bar on a strong ebb against an incoming Pacific swell is what the Coast Guard's motor lifeboat school exists to train against. Photographers on the Astoria Riverwalk and bird-walkers at the Trestle Bay reserve at the Lewis and Clark NWR read the table for the lowest lows and the calm slack-water windows. Predictions on this page come from NOAA CO-OPS station 9439040. Pacific storm surge in winter can lift water levels 20 cm or more above predicted; the table assumes calm.

Tide questions about Astoria (Columbia River), OR

When is the next high tide at Astoria?
The hero block shows the next high tide at the Tongue Point gauge in local Pacific time. The 7-day table covers all four daily extremes. River discharge from the Columbia adds a non-tidal component to actual water levels, especially during spring runoff in May and June; harmonic predictions describe the astronomical tide only.
What's the typical tide range at Astoria?
Mean range at Astoria is about 2.4 metres, climbing past 2.9 metres on spring tides and dropping near 1.6 on neaps. The river-mouth amplifies the open-Pacific signal modestly; further inland up the Columbia toward Vancouver and Portland the range damps significantly as the river takes over from the tide.
Where do these tide predictions come from?
NOAA CO-OPS station 9439040 at Tongue Point, just east of Astoria. NOAA's harmonic predictions resolve both the astronomical tide and the long-period river-cycle component. Accuracy is navigation-grade under normal weather. The Columbia Bar's pilots maintain their own real-time current and surge information for ship traffic, which is the authoritative source for crossing decisions.
When are the lowest lows for the Trestle Bay flats?
The lowest lows — minus tides below MLLW — cluster around new and full moons, especially late autumn through early spring. The 7-day table flags each day's lowest predicted tide. Trestle Bay and the broader Lewis and Clark NWR flats open up best at the bottom of these cycles, exposing mudflats that hold dunlin, plovers, and the occasional sandhill crane in passage.
Is this safe to use for navigation?
No. The Columbia Bar is one of the most heavily piloted ship channels in North America for a reason. For any small-craft transit of the bar use the Coast Guard's bar restrictions, NOAA's authoritative chart products, and the latest pilot-station information. The breaking water on a strong ebb against incoming Pacific swell is real and lethal; this site is a planning tool, not a crossing decision.
