Heights are above mean lower low water (MLLW), the zero of US charts; times are local. The year’s tides are NOAA’s official predictions - wind and air pressure can move the real water a foot or more. Form number: (K1+O1)/(M2+S2) from NOAA’s harmonic constants - below 0.25 twice-daily, above 3 once-daily. Texas, 28.118°N 97.022°W. Predictions and records: NOAA CO-OPS, station 8774513.
