When is the lowest tide this week in Plymouth, MA?

The lowest tide this week in Plymouth, MA is -0.6 ft on Monday, Jul 13 at 4:58 am.

When is the highest tide this week in Plymouth, MA?

The highest tide this week in Plymouth, MA is 11.6 ft on Sunday, Jul 12 at 10:19 pm — worth noting for launching your boat and being alert for possible high tide flooding.

What time does the tide turn (slack tide) in Plymouth, MA today?

Slack tide in Plymouth, MA is approximately 2:14 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 Plymouth, MA?

Plymouth, MA is currently in a transitional phase. Tonight's moon is 62% 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 Plymouth, 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 Plymouth, MA?

Tide predictions for Plymouth, 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 Plymouth, MA?

Tide data for Plymouth, MA is sourced from NOAA Station #8446493. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=8446493.

What time is high tide in Plymouth, MA today?

High tides in Plymouth, MA today: 4:19 am (9.8 ft), 4:50 pm (9.7 ft).

What time is low tide in Plymouth, MA today?

Low tides in Plymouth, MA today: 10:53 am (1.0 ft), 11:18 pm (1.4 ft).

What is the tidal range in Plymouth, MA today?

Today's tidal range in Plymouth, MA is 8.8 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 below-average.

What is the moon phase in Plymouth, MA tonight?

Tonight the moon over Plymouth, MA is Third Quarter (62% illuminated). This places Plymouth, MA in a transitional tide cycle, so tidal ranges are shifting between spring and neap this week.

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

Plymouth, MA 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.
