Common Questions About Westport Harbor, MA Tides

Collapse All
When is the lowest tide this week in Westport Harbor, MA?

The lowest tide this week in Westport Harbor, MA is 0.4 ft on Wednesday, Sep 23 at 12:18 pm.

When is the highest tide this week in Westport Harbor, MA?

The highest tide this week in Westport Harbor, MA is 2.8 ft on Thursday, Sep 17 at 1:12 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 Westport Harbor, MA?

Westport Harbor, MA is currently in a transitional phase. Tonight's moon is 30% 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 shifting between spring and neap.

What datum are Westport Harbor, MA 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 Westport Harbor, MA?

Tide predictions for Westport Harbor, MA 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 Westport Harbor, MA?

Tide data for Westport Harbor, MA is sourced from NOAA Station #8447975. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=8447975.

What time is high tide in Westport Harbor, MA today?

High tides in Westport Harbor, MA today: 12:23 pm (3.1 ft).

What time is low tide in Westport Harbor, MA today?

Low tides in Westport Harbor, MA today: 5:19 am (0.4 ft), 6:09 pm (0.7 ft).

What is the tidal range in Westport Harbor, MA today?

Today's tidal range in Westport Harbor, MA is 2.7 ft — the difference between the day's highest and lowest water level. This month's average daily range is about 3.1 ft, so today's swing is typical.

What is the moon phase in Westport Harbor, MA tonight?

Tonight the moon over Westport Harbor, MA is Waxing Crescent (30% illuminated). This places Westport Harbor, MA in a transitional tide cycle, so tidal ranges are shifting between spring and neap this week.

What type of tides does Westport Harbor, MA have — semi-diurnal, diurnal, or mixed?

Westport Harbor, MA 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.
