King tides in Texas, 2027

The biggest predicted tide in Texas in 2027 reaches 2.2 ft above MLLW at Battleship Texas State Park on Friday, September 24, at 8:16 AMlocal time. Below are all of the year's king tide windows — the top 1% of predicted highs — for NOAA reference stations along the Texascoast. King tides are perigean spring tides: they arrive when a full or new moon lines up with the moon's closest approach to Earth, and they preview the flooding that sea level rise will make routine.

NOAA CO-OPS harmonic predictions, datum MLLW, station local time. Actual water level can run higher with storms, onshore wind, and low pressure — king tide + storm is the flooding combination to watch. Predictions are for planning, not navigation.
