In February 2015, CDIP updated the 'Flooding Index' forecast plots. In accordance with current reseach on wave runup, the new plots are not based only on the tide and wave height, but also take the wave period into account. The resulting water level predictions are generally lower than those from the old model, but they should be significantly more representative of the actual water levels observed at the coast. For more information, please refer the CDIP water level forecast documentation.

For a comparison of forecast and real-time, buoy-driven water level predictions, please see the water level comparison plot.

For the latest tide predictions please see NOAA Tides & Currents.
