Provider:Deutscher Wetterdienst, DWD, Germany
Model scope:Germany
Update frequency:every 12 hours
Resolution:[0.8nm, 1.5km] x [0.5nm, 1.0km]
Model duration:16 forecasts starting at 3 hrs, ending at 2 days
Parameters:wind, wind wave, swell, swell/wave combined
GRIB model date:Mon Jun 17 12:00:00 2024 UTC
Download date:Mon Jun 17 16:30:55 2024 UTC

Note: the Download delay is the amount of time required for the GRIB model to compute its forecast and then for the LuckGrib cluster to download the data and make it available. The LuckGrib delay is generally less than 10 minutes, the remainder of the delay is the model compute time.


The DWD Coast Wave model is a high resolution model covering Germany’s coastline, generating wave information, including wind waves and swell.

Ocean wave forecasts based on DWD-Model ICON

The numerical wave model represents an integral part of the operational weather prediction system. Therefore, wave forecasts directly depend on the forcing by analyzed and forecast 10m-winds of the atmospheric model ICON.

Internally, the wave model describes the local sea state as a 2-dimensional distribution of wave energy with respect to wave period and the direction of propagation. In the present version, a wave spectrum represents 36 directions und 30 wave periods from 1.5 to 24 seconds.
