ECMWF is now running a series of data-driven forecasts as part of its experimental suite. These machine-learning based models are very fast, and they produce a 10-day forecast with 6-hourly time steps in approximately one minute. The outputs are available in graphical form.
Currently, three of these models are available:
Interval/period: N/A
Mean wave period is the spectrally averaged period of the waves. Wave periods are shown in seconds using colour shading – click on the middle icon to the bottom right for the scale...

Interval/period: N/A
Mean windsea wave direction is the spectrally averaged direction of propagation of the windsea waves (weighted by wave height). Arrow length is proportional to the speed of wave propagation...
Interval/period: N/A
Significant windsea wave height can be shown to correspond to the average wave height of the top one-third highest windsea waves. Wave heights are shown in metres using colour shading...

These charts show probability of various heights of significant waves 10-15 days ahead. The ...
Interval/period: N/A
Mean total swell wave direction is the spectrally averaged propagation direction of the swell waves (weighted by wave height) of the part of the spectrum that is NOT windsea...
Interval/period: N/A
Wave height is the vertical distance between trough and crest. Wave period is the time between the passage of one wave crest and the next. The arrow direction is the direction the waves are moving towards...

ECMWF is now running its own Artificial Intelligence Forecasting System (AIFS). The AIFS consists of a deterministic model and an ensemble model. The deterministic model has been running operationally since 25 February 2025; further details can be found on the dedicated Implementation of AIFS Single v1 page.
