Frequently Asked Questions
1/ How do I register or join up to PredictWind?
If you are not already registered with PredictWind you can sign up for free at https://forecast.predictwind.com/en/register/free/yourDetails
2/ Which model is the best or most accurate?
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.
You can also check the live real-time observations in your area to see which model is tracking best.
