About the tides at Port Isabel

Tides at Port Isabel are mostly diurnal: one rise and one fall a day, with a slow change between them. Water here rises and falls only about 1.2 ft on an average day. A strong onshore wind can push levels above the prediction. From the average lower low to the average higher high, the difference is 1.4 ft. Over the next two weeks the biggest daily range, 2.0 ft, comes on Friday, and the smallest, 0.7 ft, on October 8.

A live NOAA gauge measures the water here, and predictions are calculated from this station's own records. It also reports water temperature, wind and air pressure. It was established in 1944. The nearest other station is Queen Isabella Causeway (west end), 2 mi away. For tidal currents, see Port Isabel Channel, North End.
