EMC Operational Wave Product Table

Due to ongoing testing and resource constraints, the GFS-Wave website graphics may be slow to update from time to time. We apologize for this inconvenience.

Operationally generated graphics of the wave fields (no spectra or source terms) are available from Model Analyses and Guidance.

Bulletin files are available from the Production FTP server. Look for gfs.YYYYMMDD/CC/wave/station/bulls.tCCz/gfswave.stationID.bull

Significant Wave Height and Peak Direction

The significant wave height is a measure for the wave height, and closely corresponds to what a trained observer would consider to be the mean wave height. Note that the highest wave height of an individual wave will be significantly larger.
