PredictWind Forecasts More Accurate Than Ever


PredictWind has made significant improvements to their weather models. 10 years of development has culminated in the release of the most accurate iteration of the PWG & PWE  forecast model to date. This means that the PredictWind models now give you more forecast confidence than ever before, making your time on the water safer and more enjoyable.

To validate the improvement, we undertook an intensive verification study using real time data from 77 weather stations around the globe. For each station 1 month of one hour interval readings were compared to the forecasts based on the new PredictWind model versus the existing model. The results of the study show on average a 12% improvement using the new PredictWind model for wind speed, and a 7% improvement in Wind Direction.
