About Gulf Coast Tides

One tide a day — the Gulf's unusual tidal rhythm

The Gulf of Mexico behaves unlike any other US coast. Most of the Gulf experiences diurnal tides — just one high tide and one low tide per day, rather than the two you'd see on the Atlantic or Pacific. This happens because the Gulf's shape and depth create a natural resonance that amplifies the once-daily tidal signal.

Tidal ranges are generally small, averaging 1–2 feet, but wind-driven water level changes can be dramatic in shallow bays and estuaries. Tampa Bay, Galveston Bay, and the shallow Louisiana marshes all respond significantly to wind and pressure as well as tidal forces — making real-time data especially useful.

Boaters & Sailors
Navigate shallow Gulf bays and inlets with real-time tidal state. Know when the one daily low tide will limit your draft.

FAQ

Gulf Coast tide questions

Why does the Gulf of Mexico only have one tide per day?
The Gulf of Mexico's shape, size, and depth create a resonance that amplifies the diurnal (once-daily) tidal component and dampens the semi-diurnal (twice-daily) one. The result is that most Gulf Coast locations experience only one high tide and one low tide per day — a pattern that surprises many visitors from the Atlantic or Pacific coasts.
What are the tides like in Tampa Bay and Galveston?
Both Tampa Bay and Galveston Bay experience the Gulf's characteristic diurnal tidal pattern with small ranges of around 1–2 feet. However, both are large, shallow bays where wind-driven water level changes can significantly alter conditions beyond the tidal prediction alone.
How many tide stations does TideSwell cover on the Gulf Coast?
TideSwell covers 54 NOAA tide stations along the Gulf Coast, from Florida's Gulf Shore across Alabama, Mississippi, Louisiana, and Texas — including Tampa Bay, Pensacola, Mobile Bay, New Orleans, Galveston, and Corpus Christi.
