When is the lowest tide this week in Adak Island, AK?

The lowest tide this week in Adak Island, AK is -1.1 ft on Saturday, Oct 3 at 5:29 am.

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

The highest tide this week in Adak Island, AK is 4.2 ft on Friday, Oct 2 at 8:18 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 Adak Island, AK?

Adak Island, AK is currently in a neap phase. Tonight's moon is 58% 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 minimum.

What datum are Adak 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 Adak Island, AK?

Tide predictions for Adak 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 Adak Island, AK?

Tide data for Adak Island, AK is sourced from NOAA Station #9461380. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=9461380.

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

High tides in Adak Island, AK today: 8:18 pm (4.2 ft).

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

Low tides in Adak Island, AK today: 4:36 am (-1.0 ft). The 4:36 am low of -1.0 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 Adak Island, AK today?

Today's tidal range in Adak Island, AK is 5.2 ft — the difference between the day's highest and lowest water level. This month's average daily range is about 3.6 ft, so today's swing is above-average.

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

Tonight the moon over Adak Island, AK is Third Quarter (58% illuminated). This places Adak Island, AK in a neap tide cycle, so tidal ranges are near their weekly minimum this week.

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

Adak Island, AK has diurnal tides — one high tide and one low tide per day, roughly every 24 hours and 50 minutes.

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.

Quietly Sophisticated: The Hood 42 LM

By US Harbors At first glance, the Hood 42 LM might be confused for a boat that worked the Maine coast fifty years ago, but upon further inspection, the fifteen coats of Epifanes varnish over mahogany and custom-cast bronze hardware reveal that this boat was built for cruising.
