Unfortunately, there is no "golden rule" for which model is more accurate. Often there are periods where one model is better, then it swaps around. If all models are similar, you can have more confidence in the forecast. If they are very different it just shows the uncertainty in the situation.

Please see the accuracy ratings of the models from a national weather centre at https://www.predictwind.com/model-validation-technical-report/ With 1-2 models it can be difficult to decide on which forecast to select, but with up to 9 models the decision is easier to see a consensus.

To clarify the terminology for the different models that PredictWind offers, see the Help article at http://help.predictwind.com/en/articles/2884560-what-does-pwg-pwe-gfs-ecmwf-spire-ukmo-hrrr-nam-arome-stand-for

When on passage, we recommend updating the weather route twice a day to get the latest information for your route.

You can also check the live real-time observations in your area to see which model is tracking best.
