When is the lowest tide this week in Aransas Pass, TX?

The lowest tide this week in Aransas Pass, TX is -0.1 ft on Sunday, Aug 23 at 6:33 pm.

When is the highest tide this week in Aransas Pass, TX?

The highest tide this week in Aransas Pass, TX is 1.4 ft on Saturday, Aug 22 at 4:27 am — worth noting for launching your boat and being alert for possible high tide flooding.

What time does the tide turn (slack tide) in Aransas Pass, TX today?

Slack tide in Aransas Pass, TX is approximately 11:04 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 Aransas Pass, TX?

Aransas Pass, TX is currently in a transitional phase. Tonight's moon is 65% 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 Aransas Pass, TX 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 Aransas Pass, TX?

Tide predictions for Aransas Pass, TX 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 Aransas Pass, TX?

Tide data for Aransas Pass, TX is sourced from NOAA Station #8775241. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=8775241.

What time is high tide in Aransas Pass, TX today?

High tides in Aransas Pass, TX today: 3:45 am (1.4 ft).

What time is low tide in Aransas Pass, TX today?

Low tides in Aransas Pass, TX today: 4:44 pm (-0.1 ft). The 4:44 pm low of -0.1 ft is a minus tide — water below the MLLW reference datum, which can expose tidepools, mudflats, and shellfish beds not normally accessible.

What is the tidal range in Aransas Pass, TX today?

Today's tidal range in Aransas Pass, TX is 1.5 ft — the difference between the day's highest and lowest water level. This month's average daily range is about 1.3 ft, so today's swing is typical.

What is the moon phase in Aransas Pass, TX tonight?

Tonight the moon over Aransas Pass, TX is First Quarter (65% illuminated). This places Aransas Pass, TX in a transitional tide cycle, so tidal ranges are shifting between spring and neap this week.

What type of tides does Aransas Pass, TX have — semi-diurnal, diurnal, or mixed?

Aransas Pass, TX has diurnal tides — one high tide and one low tide per day, roughly every 24 hours and 50 minutes.

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.
