When is the lowest tide this week in Steamboat Bay, Noyes Island, AK?

The lowest tide this week in Steamboat Bay, Noyes Island, AK is -2.0 ft on Thursday, Aug 13 at 7:49 am.

When is the highest tide this week in Steamboat Bay, Noyes Island, AK?

The highest tide this week in Steamboat Bay, Noyes Island, AK is 11.3 ft on Friday, Aug 14 at 2:00 am — worth noting for launching your boat and being alert for possible high tide flooding.

What time does the tide turn (slack tide) in Steamboat Bay, Noyes Island, AK today?

Slack tide in Steamboat Bay, Noyes Island, AK is approximately 11:01 am — 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 Steamboat Bay, Noyes Island, AK?

Steamboat Bay, Noyes Island, AK is currently in a spring phase. Tonight's moon is 2% 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 Steamboat Bay, Noyes 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 Steamboat Bay, Noyes Island, AK?

Tide predictions for Steamboat Bay, Noyes 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 Steamboat Bay, Noyes Island, AK?

Tide data for Steamboat Bay, Noyes Island, AK is sourced from NOAA Station #9450578. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=9450578.

What time is high tide in Steamboat Bay, Noyes Island, AK today?

High tides in Steamboat Bay, Noyes Island, AK today: 1:13 am (11.6 ft), 2:14 pm (10.2 ft). The 1:13 am high of 11.6 ft is notably higher than the other — known as diurnal inequality, common on coasts influenced by lunar declination.

What time is low tide in Steamboat Bay, Noyes Island, AK today?

Low tides in Steamboat Bay, Noyes Island, AK today: 7:49 am (-2.0 ft), 7:59 pm (1.0 ft). The 7:49 am low of -2.0 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 Steamboat Bay, Noyes Island, AK today?

Today's tidal range in Steamboat Bay, Noyes Island, AK is 13.7 ft — the difference between the day's highest and lowest water level. This month's average daily range is about 9.9 ft, so today's swing is above-average.

What is the moon phase in Steamboat Bay, Noyes Island, AK tonight?

Tonight the moon over Steamboat Bay, Noyes Island, AK is New Moon (2% illuminated). This places Steamboat Bay, Noyes Island, AK in a spring tide cycle, so tidal ranges are near their weekly maximum this week.

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

Steamboat Bay, Noyes Island, AK has semi-diurnal tides — two high tides and two low tides roughly every 24 hours and 50 minutes, with similar heights.

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.
