What tidal current predictions and observed current data are available?
The availability of tidal current predictions and observed current data is limited compared to the availability of tide data. Continuous measurements of currents were not possible until recently. Short deployments of current meters at various estuaries have been carried out for over 100 years. Archived data sets are available but data quality can vary considerably based on the age of the data and location of the measurements. Data from the last 30 years is in digital form; older data exist as paper transcripts. Inquiries about specific locations to ascertain if data exists, its quality and availability will be answered by our office. You can contact our office at (301) 713-2815 between 7AM-3PM Eastern Time. You may also submit an inquiry to our e-mail address at: Tide.Predictions@noaa.gov. Recent current observations exist where a National Ocean Service (NOS) PORTS is installed, for example, Houston/Galveston, Tampa Bay, San Francisco Bay, New York/New Jersey Harbor, and Narragansett B
