When is the lowest tide this week in Astoria (Port Docks), OR?

The lowest tide this week in Astoria (Port Docks), OR is 0.1 ft on Wednesday, Sep 23 at 5:58 am.

When is the highest tide this week in Astoria (Port Docks), OR?

The highest tide this week in Astoria (Port Docks), OR is 7.1 ft on Thursday, Sep 17 at 5:27 pm — worth noting for launching your boat and being alert for possible high tide flooding.

Is this week a spring tide or neap tide in Astoria (Port Docks), OR?

Astoria (Port Docks), OR is currently in a transitional phase. Tonight's moon is 31% illuminated. Spring tides (largest swings) occur near new and full moons; neap tides (smallest swings) occur near first and third quarter moons. Tidal ranges this week are shifting between spring and neap.

What datum are Astoria (Port Docks), OR tide heights measured from?

Tide heights on this page are measured from Mean Lower Low Water (MLLW), the U.S. NOAA standard. A height of 0 ft represents the 19-year average of each day's lower low tide. Negative values indicate a "minus tide" — water levels below that long-term reference.

What factors can affect the tide predictions for Astoria (Port Docks), OR?

Tide predictions for Astoria (Port Docks), OR come from NOAA's harmonic analysis and are typically accurate within about ±10 minutes on timing and ±0.5 ft on height. Actual water levels can deviate further due to sustained winds, atmospheric pressure changes, river flow, and storm surge. During major weather events, be sure to check US Harbors weather pages for factors that could impact tidal predictions.

Which NOAA station provides tide data for Astoria (Port Docks), OR?

Tide data for Astoria (Port Docks), OR is sourced from NOAA Station #9439023. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=9439023.

What time is high tide in Astoria (Port Docks), OR today?

High tides in Astoria (Port Docks), OR today: 5:37 am (5.8 ft), 4:50 pm (7.5 ft). The 4:50 pm high of 7.5 ft is notably higher than the other — known as diurnal inequality, common on coasts influenced by lunar declination.

What time is low tide in Astoria (Port Docks), OR today?

Low tides in Astoria (Port Docks), OR today: 10:59 am (2.4 ft).

What is the tidal range in Astoria (Port Docks), OR today?

Today's tidal range in Astoria (Port Docks), OR is 5.1 ft — the difference between the day's highest and lowest water level. This month's average daily range is about 7.6 ft, so today's swing is below-average.

What is the moon phase in Astoria (Port Docks), OR tonight?

Tonight the moon over Astoria (Port Docks), OR is Waxing Crescent (31% illuminated). This places Astoria (Port Docks), OR in a transitional tide cycle, so tidal ranges are shifting between spring and neap this week.

What type of tides does Astoria (Port Docks), OR have — semi-diurnal, diurnal, or mixed?

Astoria (Port Docks), OR has mixed tides — two high tides and two low tides per day with noticeably different heights — common on the U.S. West Coast.

US Harbors Tidal Data

The data in our tide charts, tide tables, and tide graphs is provided by NOAA and others. These predictions are derived mathematically from numerous inputs, including data from historical tide stations and nearby locations where sensors are actively recording. As shown in the tide graph at the top of this page, “Predicted” tides (blue) are what forecasting models expect to happen. “Observed” tides (red) are those recorded by local sensors in real time, overlaid on the predictions for direct comparison. We display Observed water levels for a select group of harbors including Portland, Maine, where a physical sensor monitors water levels in real time.
