When is the lowest tide this week in Port Tobacco River, MD?

The lowest tide this week in Port Tobacco River, MD is 0.1 ft on Thursday, Aug 13 at 11:08 am.

When is the highest tide this week in Port Tobacco River, MD?

The highest tide this week in Port Tobacco River, MD is 1.8 ft on Wednesday, Aug 12 at 3:58 am — worth noting for launching your boat and being alert for possible high tide flooding.

What time does the tide turn (slack tide) in Port Tobacco River, MD today?

Slack tide in Port Tobacco River, MD is approximately 9:35 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 Port Tobacco River, MD?

Port Tobacco River, MD is currently in a transitional phase. Tonight's moon is 22% 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 Port Tobacco River, MD 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 Tobacco River, MD?

Tide predictions for Port Tobacco River, MD 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 Tobacco River, MD?

Tide data for Port Tobacco River, MD is sourced from NOAA Station #8578769. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=8578769.

What time is high tide in Port Tobacco River, MD today?

High tides in Port Tobacco River, MD today: 12:37 pm (1.4 ft).

What time is low tide in Port Tobacco River, MD today?

Low tides in Port Tobacco River, MD today: 6:34 am (0.4 ft), 6:10 pm (0.4 ft).

What is the tidal range in Port Tobacco River, MD today?

Today's tidal range in Port Tobacco River, MD is 1.1 ft — the difference between the day's highest and lowest water level. This month's average daily range is about 1.5 ft, so today's swing is typical.

What is the moon phase in Port Tobacco River, MD tonight?

Tonight the moon over Port Tobacco River, MD is Waning Crescent (22% illuminated). This places Port Tobacco River, MD in a transitional tide cycle, so tidal ranges are shifting between spring and neap this week.

What type of tides does Port Tobacco River, MD have — semi-diurnal, diurnal, or mixed?

Port Tobacco River, MD 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.
