Common Questions About Portland, ME Tides

Collapse All
Is this week a spring tide or neap tide in Portland, ME?

Portland, ME is currently in a spring phase. Tonight's moon is 81% 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 Portland, ME 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 Portland, ME?

Tide predictions for Portland, ME 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 Portland, ME?

Tide data for Portland, ME is sourced from NOAA Station #8418150. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=8418150.

What is the moon phase in Portland, ME tonight?

Tonight the moon over Portland, ME is Waxing Gibbous (81% illuminated). This places Portland, ME in a spring tide cycle, so tidal ranges are near their weekly maximum this week.

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.

A researcher in a U.S. Coast Guard helicopter first spotted the entangled humpback anchored to the bottom about 20 miles off the Oregon Coast. The whale’s white pectoral flipper extends underwater to the lower left, while white baleen outlines its open lower jaw at bottom right. The entanglement left the whale’s mouth stretched permanently open, making it unable to feed. Photo collected in partnership with Oregon Coast Aquarium, Oregon State University Marine Mammal Institute and Cascadia Research Collective.

NOAA's GOES West satellite captured this image of three tropical cyclones — Hurricanes Fausto and Genevieve and Typhoon Dolphin — swirling simultaneously in the Pacific Ocean. The image was taken on Tuesday, July 27, at 3:30 PM PDT/ 22:30 UTC. None of the three tropical cyclones made landfall in the United States. Fausto contributed to high surf conditions in Hawaii, and Genevieve also brought high surf to southern California. Typhoon Dolphin continued its track west toward Asia.
