Common Questions About Port Protection, Prince of Wales Island, AK Tides

Collapse All
When is the lowest tide this week in Port Protection, Prince of Wales Island, AK?

The lowest tide this week in Port Protection, Prince of Wales Island, AK is -0.4 ft on Sunday, Sep 13 at 9:02 pm.

When is the highest tide this week in Port Protection, Prince of Wales Island, AK?

The highest tide this week in Port Protection, Prince of Wales Island, AK is 12.8 ft on Monday, Sep 14 at 3:07 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 Port Protection, Prince of Wales Island, AK?

Port Protection, Prince of Wales Island, AK is currently in a spring phase. Tonight's moon is 8% 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 Protection, Prince of Wales 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 Protection, Prince of Wales Island, AK?

Tide predictions for Port Protection, Prince of Wales 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 Protection, Prince of Wales Island, AK?

Tide data for Port Protection, Prince of Wales Island, AK is sourced from NOAA Station #9451095. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=9451095.

What time is high tide in Port Protection, Prince of Wales Island, AK today?

High tides in Port Protection, Prince of Wales Island, AK today: 2:30 am (12.3 ft), 2:37 pm (13.1 ft). The 2:37 pm high of 13.1 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 Protection, Prince of Wales Island, AK today?

Low tides in Port Protection, Prince of Wales Island, AK today: 8:30 am (0.6 ft), 9:02 pm (-0.4 ft). The 9:02 pm low of -0.4 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 Port Protection, Prince of Wales Island, AK today?

Today's tidal range in Port Protection, Prince of Wales Island, AK is 13.4 ft — the difference between the day's highest and lowest water level. This month's average daily range is about 11.7 ft, so today's swing is above-average.

What is the moon phase in Port Protection, Prince of Wales Island, AK tonight?

Tonight the moon over Port Protection, Prince of Wales Island, AK is Waxing Crescent (8% illuminated). This places Port Protection, Prince of Wales Island, AK in a spring tide cycle, so tidal ranges are near their weekly maximum this week.

What type of tides does Port Protection, Prince of Wales Island, AK have — semi-diurnal, diurnal, or mixed?

Port Protection, Prince of Wales 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.
