NOTICE: The predicted current values may differ substantially from the observations. The predicted values represent only the tidal portion of the surface current. Other factors that influence the currents, like wind, are not included in the prediction.

The observed current data are derived from the High Frequency Radar National Network (HFRNet), an extensive network of observations for monitoring surface currents along the coastlines of the United States. HFRNet provides reliable data telemetry, archiving, and integrated processing for a growing list of near real-time products in a scaleable manner for a growing user community and is supported by the Integrated Ocean Observing System (IOOS). For more information on HFRNet, or for historic data, go to HFRNet.
