Port Aransas Tide Chart

Predictions are pulled live from the NOAA Tides & Currents API (station 8775870 — Bob Hall Pier, on Padre Island, the closest NOAA tide station to Port Aransas and Cinnamon Shore). Heights are in feet relative to MLLW (Mean Lower Low Water) and times are in local Texas time (lst_ldt). NOAA tide predictions are based on long-term harmonic analysis and are typically accurate to a few minutes in time and a few tenths of a foot in height. Actual water levels can differ on a given day with strong winds, low pressure, or storm surge.

The Texas Gulf coast has a diurnal-mixed tide regime. On many days you'll see one clear high and one clear low (a true diurnal day); on others you'll see a higher-high, a lower-high, a higher-low, and a lower-low (a mixed semidiurnal day). The pattern shifts gradually with the moon's declination over the lunar month. This is normal and is reflected in the chart above.

For walking and shell-hunting, low and falling tides expose more beach and wet, packed sand — the best surface to walk on. For swimming with smaller kids, a falling tide an hour or two past high is often calmer and shallower nearer shore. Always check the Port Aransas Beach Patrol flag colors at the beach before getting in regardless of the tide.

Local surf-fishing wisdom on Mustang Island favors moving water — the two hours on either side of a tide change, when current is strongest and bait is moving. A rising tide late in the day is a classic redfish window; the change of tide at dawn is a classic speckled trout window. Spring tides (around full and new moons) push the most water and tend to fish best.

On the Lighthouse Lakes / Aransas Bay side, plan your launch around a rising or high tide so the back lakes are floatable and the marsh shorelines are accessible. Returning on a falling tide can leave you dragging a kayak across exposed flats — not dangerous, just a slog.

On a routine astronomical high tide, no — the dry beach in front of Cinnamon Shore stays dry. King tides (the highest tides of the year, typically October–December and May–June around new and full moons), strong onshore winds, low pressure, or storm surge can push water further up the beach and occasionally onto low-lying access roads. The chart on this page will show you when to expect a routinely higher-than-usual tide.

Texas observes Daylight Saving Time. NOAA returns predictions in local standard or daylight time depending on the date (lst_ldt). The chart on this page uses the same local time NOAA returns. If your phone's clock is set to a different time zone, the times will display in your local time; the absolute moment of high or low tide is the same.
