NOAA Tides and Currents

NOAA Tides and Currents provides real-time data and forecasts about ocean water levels and movement along U.S. coasts. Tides are the rise and fall of sea levels caused mainly by the moon's gravitational pull, while currents are the continuous flow of water driven by wind, Earth's rotation, and temperature differences. This information helps in navigation, coastal planning, and understanding environmental changes. NOAA’s data includes predictions of high and low tide times, current directions and speeds, and other important ocean conditions, supporting safety, commerce, and marine research.
