Whilst we believe the PredictWind technology is the best on the market, the forecasts will only be correct 85% of the time - which means in any given month you can expect 5 days of inaccurate forecasts.

If you check the forecasts for less than 7 days a month, you are getting a very poor sample to make an objective assessment of the accuracy of PredictWind.

In addition to the PredictWind models, we also provide the GFS (Global Forecast System) from NCEP as this is used by most other weather websites/apps. We also supply the ECMWF forecast from ECMWF (European Center for Medium-Range Weather Forecasts) that is highly regarded by Meteorologists and top Navigators around the world.

The ECMWF model is operated at 9 km resolution with full global coverage. Also, we provide the UKMO model (UK Met Service) and the SPIRE model which excels in offshore locations.

If all 6 weather models (PWG, PWE, ECMWF, SPIRE, UKMO, GFS) were not accurate, it is unlikely that any other weather website would do a better job for accuracy. Please see the accuracy ratings of the models at https://www.predictwind.com/model-validation-technical-report/

We regularly get great feedback on the accuracy and are used by leaders in the field - you can read more at http://www.predictwind.com/testimonials/
