The content provided on this page supports model development. These are not official NWS products and should not be relied upon for operational purposes. This web site is not subject to 24/7 support, and thus may be unavailable during system outages.

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/HTTPS 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.
