NOAA Tides & Currents

NOAA Tides & Currents is the starting point for a U.S. coastal trip when the question is what the water is doing, rather than whether a generic app predicts a bite. Choose a station to inspect official high and low tide predictions, recent measured water levels, tidal currents and available meteorological observations. PORTS installations add real-time wind, salinity and water-temperature information at many seaports, while coastal models provide short nowcasts and forecasts. The station identity and datum make the numbers traceable.

An astronomical prediction is not the same thing as the water level that wind, pressure, waves or river discharge will produce. Coverage is concentrated on U.S. coasts and not every station measures every parameter. Anglers should compare predicted and observed levels, read current warnings, and use the appropriate chart datum before making a launch or wading decision. This service helps describe conditions; it does not estimate fish behavior or replace a marine weather and safety check.
