The tide at Copano Bay
Copano Bay has a diurnal tide: usually one high and one low a day, with the daily rhythm shifting about 50 minutes later each day and fading near the moon's equatorial crossing. This month's predictions average 1.0 high tides a day here. The mean range from lower low to higher high is 0.4 ft, a small tide. For the water around it: Texas tides are diurnal, usually one high and one low a day with a range near 1 to 2 ft, and a steady wind can hold the predicted tide off by a foot.

Datum and source
Heights on this page are feet above mean lower low water (MLLW), the zero NOAA's nautical charts use for soundings. A predicted 0.0 ft low is the average of the lower low each day; a minus tide is water below chart datum, and a 2 ft high means 2 ft more water than the chart shows. NOAA fixes MLLW at Copano Bay from the 2002-2006 National Tidal Datum Epoch; mean higher high water is 0.4 ft above it and mean sea level 0.2 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 0.6 ft below MLLW here, so a water level on this page converts to NAVD88 by adding that amount. These datums are controlled from NOAA's Rockport, TX gauge. Source: NOAA CO-OPS station 8774513, established 2004. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them. The observed line is the gauge's own six-minute water level feed.
