We’re excited to announce a major upgrade to our weather model suite, introducing three powerful global models - 

Forecasting technology continues to evolve rapidly, especially with advances in AI and machine learning. The new 

 models have shown excellent results in global validation studies, delivering improved forecast accuracy in both the short and medium term. These updates ensure PredictWind users have access to the most advanced and reliable forecasting data available.


This is PredictWind's own proprietary global model. It combines the strengths of ECMWF, AIFS, Fengwu, and GraphCast to generate a single, optimized forecast covering the globe. It provides 1-hour time steps for the first three days, giving greater time-step precision than other AI models. PWAi performs strongly in validation studies in the short to medium term over larger-scale areas. It will be a key reference model for establishing consensus across the PredictWind suite.


The ECMWF AIFS model uses advanced AI to deliver timely, accurate global forecasts. It performs especially well offshore, capturing large-scale weather patterns in the medium to longer term, giving mariners a clear, data-driven view of changing conditions.

Produced by the German Weather Service (DWD), ICON is renowned for its high-resolution accuracy in Europe and is now available globally through PredictWind.

You can learn more about each models strengths and limitations in our new models page 


And check out the evaluation study of the PWAI 

Together, these models set a new benchmark in forecasting, giving you more confidence in every decision - from daily planning to offshore passages.

Included in these changes are the removal of the Spire model, which is being deprecated by Spire.
