How accurate are we?

We have an open and transparent policy on how we verify the accuracy of our forecasts.

Verification involves comparing our forecasts against relevant observations to determine how accurate they are. Verification therefore underpins the Forecast Accuracy Business Performance Measure (BPM) which is set by government. These BPMs are part of our ongoing long-term commitment to improving the accuracy of our forecasts to the public. We will do this by reaching accuracy targets set for the forecasting skill of our Global and UK Numerical Weather Prediction (NWP) computer models.
