Tide Charts by City
What time is high tide? Each city page leads with whether the tide is rising or falling right now and when the next high or low hits, then lays out today’s full schedule in feet relative to MLLW, a 7-day outlook, and a 24-hour tide curve wherever NOAA publishes 6-minute predictions for the station. Built on open NOAA CO-OPS predictions — no ads, no app, across 150 U.S. coastal cities.

Frequently asked
- What does MLLW mean on a tide chart?
- MLLW stands for Mean Lower Low Water — the average of the lower of each day's two low tides over NOAA's 19-year National Tidal Datum Epoch. It is the zero line for tide heights, so a predicted 5.0 ft means five feet above that average, and a negative height means the water drops below it.
- How accurate are tide predictions?
- NOAA's astronomical predictions are reliable for the timing and height of normal tides, but they do not include weather: strong onshore or offshore winds, storm surge, and unusual air pressure can raise or lower the actual water level beyond the prediction.
- Why do some places get two high tides a day and others one?
- The Moon's gravity and the Earth's rotation produce two tidal bulges, so most of the U.S. Atlantic coast sees two highs and two lows of similar height each lunar day (about 24 hours 50 minutes), a semidiurnal tide. The Pacific coast usually sees two highs of unequal height (a mixed tide), and parts of the Gulf of Mexico see just one high and one low a day (a diurnal tide).
- What is a spring tide versus a neap tide?
- Spring tides are the largest ranges — higher highs and lower lows — around the new and full Moon, when the Sun and Moon line up and their pulls add. Neap tides are the smallest ranges, near the first- and third-quarter Moon, when the Sun and Moon pull at right angles.
