Due to limited computational resources through Friday Sep 17, the GFS-Wave website graphics will be very slow to update until next week. We apologize for the delay.

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
NCEP/EMC is seeking public commentary on the GFS-Wave website and its contents, which will help decide if this site will continue to be supported. We would very much appreciate your input. This form will close on September 30th, 2021.

About this product:

The secondary swell period identifies the period (the time between waves) of the next-to-dominant wave system (swell) that is generated elsewhere.
