When is the lowest tide this week in Bay Shore, NY?

The lowest tide this week in Bay Shore, NY is 0.3 ft on Tuesday, Sep 15 at 8:07 pm.

When is the highest tide this week in Bay Shore, NY?

The highest tide this week in Bay Shore, NY is 1.1 ft on Wednesday, Sep 16 at 2:27 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 Bay Shore, NY?

Bay Shore, NY is currently in a transitional phase. Tonight's moon is 21% 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 Bay Shore, NY 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 Bay Shore, NY?

Tide predictions for Bay Shore, NY 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 Bay Shore, NY?

Tide data for Bay Shore, NY is sourced from NOAA Station #8515102. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=8515102.

What time is high tide in Bay Shore, NY today?

High tides in Bay Shore, NY today: 1:13 am (1.1 ft), 1:40 pm (1.2 ft).

What time is low tide in Bay Shore, NY today?

Low tides in Bay Shore, NY today: 7:33 am (0.2 ft), 8:07 pm (0.3 ft).

What is the tidal range in Bay Shore, NY today?

Today's tidal range in Bay Shore, NY is 1.0 ft — the difference between the day's highest and lowest water level. This month's average daily range is about 1.0 ft, so today's swing is typical.

What is the moon phase in Bay Shore, NY tonight?

Tonight the moon over Bay Shore, NY is Waxing Crescent (21% illuminated). This places Bay Shore, NY in a transitional tide cycle, so tidal ranges are shifting between spring and neap this week.

What type of tides does Bay Shore, NY have — semi-diurnal, diurnal, or mixed?

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.
