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

About this product:

The wind sea period identifies the period (the time between waves) of the locally generated waves (in cases with strong local winds). Note that the peak period field shows discontinuities. These discontinuities can loosely be interpreted as swell fronts, although in reality many swell systems overlap at most locations and times.
