Common Questions About Clear Lake, Galveston Bay, TX Tides

Collapse All
When is the lowest tide this week in Clear Lake, Galveston Bay, TX?

The lowest tide this week in Clear Lake, Galveston Bay, TX is 0.2 ft on Tuesday, Sep 15 at 6:48 pm.

When is the highest tide this week in Clear Lake, Galveston Bay, TX?

The highest tide this week in Clear Lake, Galveston Bay, TX is 1.4 ft on Thursday, Sep 17 at 7:06 am — worth noting for launching your boat and being alert for possible high tide flooding.

Is this week a spring tide or neap tide in Clear Lake, Galveston Bay, TX?

Clear Lake, Galveston Bay, TX is currently in a spring phase. Tonight's moon is 0% 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 Clear Lake, Galveston Bay, 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 Clear Lake, Galveston Bay, TX?

Tide predictions for Clear Lake, Galveston Bay, 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 Clear Lake, Galveston Bay, TX?

Tide data for Clear Lake, Galveston Bay, TX is sourced from NOAA Station #8770933. View the official NOAA station page at https://tidesandcurrents.noaa.gov/stationhome.html?id=8770933.

What time is high tide in Clear Lake, Galveston Bay, TX today?

High tides in Clear Lake, Galveston Bay, TX today: 11:23 am (1.1 ft), 8:36 pm (1.1 ft).

What time is low tide in Clear Lake, Galveston Bay, TX today?

What is the tidal range in Clear Lake, Galveston Bay, TX today?

What is the moon phase in Clear Lake, Galveston Bay, TX tonight?

Tonight the moon over Clear Lake, Galveston Bay, TX is New Moon (0% illuminated). This places Clear Lake, Galveston Bay, TX in a spring tide cycle, so tidal ranges are near their weekly maximum this week.

What type of tides does Clear Lake, Galveston Bay, TX 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.
