The forecast probability % sits on the right hand side of the chart.


What does it mean?

A forecast showing 100% probability does not mean it will definitely happen.

Our 21 swell models use slightly different starting conditions to predict future wind and swell.

The resulting percentage score is based on how close the models are in their forecasts. The higher the % the less likely the forecast is to change.

A 100% probability score means there is consensus among the models, but like any weather-related forecast, the model guidance may prove to be incorrect.
