Common Questions About Coronation Island, AK Tides

Show All
When is the lowest tide this week in Coronation Island, AK?

The lowest tide this week in Coronation Island, AK is -3.0 ft on Wednesday, Jul 15 at 8:06 am.

When is the highest tide this week in Coronation Island, AK?

The highest tide this week in Coronation Island, AK is 12.4 ft on Wednesday, Jul 15 at 1:15 am — worth noting for launching your boat and being alert for possible high tide flooding.

What time does the tide turn (slack tide) in Coronation Island, AK today?

Slack tide in Coronation Island, AK is approximately 3:46 pm — midway between the next high and low tide, when tidal current is weakest. This is the preferred window for boat crossings, underwater visibility, and fishing in areas with strong currents.

Is this week a spring tide or neap tide in Coronation Island, AK?

Coronation Island, AK is currently in a spring phase. Tonight's moon is 1% 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 near their weekly maximum.

What datum are Coronation Island, AK 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 Coronation Island, AK?

Tide predictions for Coronation Island, AK 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 Coronation Island, AK?

Tide data for Coronation Island, AK is sourced from NOAA Station #9450829. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=9450829.

What time is high tide in Coronation Island, AK today?

High tides in Coronation Island, AK today: 1:12 pm (9.2 ft).

What time is low tide in Coronation Island, AK today?

Low tides in Coronation Island, AK today: 6:32 am (-2.5 ft), 6:20 pm (3.2 ft). The 6:32 am low of -2.5 ft is a minus tide — water below the MLLW reference datum, which can expose tidepools, mudflats, and shellfish beds not normally accessible.

What is the tidal range in Coronation Island, AK today?

Today's tidal range in Coronation Island, AK is 11.7 ft — the difference between the day's highest and lowest water level. This month's average daily range is about 10.8 ft, so today's swing is above-average.

What is the moon phase in Coronation Island, AK tonight?

Tonight the moon over Coronation Island, AK is New Moon (1% illuminated). This places Coronation Island, AK in a spring tide cycle, so tidal ranges are near their weekly maximum this week.

What type of tides does Coronation Island, AK have — semi-diurnal, diurnal, or mixed?

Coronation Island, AK 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.
