When is the highest tide this week in Port Beauclerc, Kuiu Island, AK?

The highest tide this week in Port Beauclerc, Kuiu Island, AK is 13.1 ft on Thursday, Aug 13 at 1:11 am — worth noting for launching your boat and being alert for possible high tide flooding.

What time does the tide turn (slack tide) in Port Beauclerc, Kuiu Island, AK today?

Slack tide in Port Beauclerc, Kuiu Island, AK is approximately 12:34 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 Port Beauclerc, Kuiu Island, AK?

Port Beauclerc, Kuiu Island, AK is currently in a spring phase. Tonight's moon is 20% 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 Port Beauclerc, Kuiu 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 Port Beauclerc, Kuiu Island, AK?

Tide predictions for Port Beauclerc, Kuiu 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 Port Beauclerc, Kuiu Island, AK?

Tide data for Port Beauclerc, Kuiu Island, AK is sourced from NOAA Station #9451082. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=9451082.

What time is high tide in Port Beauclerc, Kuiu Island, AK today?

High tides in Port Beauclerc, Kuiu Island, AK today: 10:15 am (8.5 ft), 9:10 pm (11.8 ft). The 9:10 pm high of 11.8 ft is notably higher than the other — known as diurnal inequality, common on coasts influenced by lunar declination.

What time is low tide in Port Beauclerc, Kuiu Island, AK today?

Low tides in Port Beauclerc, Kuiu Island, AK today: 3:29 am (0.1 ft), 2:54 pm (4.4 ft).

What is the tidal range in Port Beauclerc, Kuiu Island, AK today?

Today's tidal range in Port Beauclerc, Kuiu 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 11.5 ft, so today's swing is typical.

What is the moon phase in Port Beauclerc, Kuiu Island, AK tonight?

Tonight the moon over Port Beauclerc, Kuiu Island, AK is Waning Crescent (20% illuminated). This places Port Beauclerc, Kuiu Island, AK in a spring tide cycle, so tidal ranges are near their weekly maximum this week.

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

Port Beauclerc, Kuiu 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.
