The Coastal Data Information Program (CDIP) specializes in wave measurement, swell modeling and forecasting, and the analysis of coastal environment data. Swell-only (wave periods > 8 sec), based on CDIP's buoy observations The Swell Nowcast predict swell only for the last six hours in nearshore and offshore waters at a 0.01 degree resolution. The
Swell Forecast predicts swell (wave periods > 4 sec) based on ECMWF global forecast for four days from present in nearshore and offshore waters at a 0.01 degree resolution. All frequencies modeled as swell, using offshore input sites only.
