ECMWF HRES Europe Accuracy: 2026 Benchmarks vs GFS & AI

1 / 5

ECMWF HRES remains the benchmark for European medium-range forecasts and beats NOAA GFS on temperature, wind, and precipitation from 3 to 7 days.

2 / 5

Jua’s EPT-2 family now surpasses HRES on every lead time and key energy variable, verified against more than 10,000 ground stations using open-source StationBench methodology.

3 / 5

HRES benefits from 9 km resolution and 4D-Var data assimilation, but Jua’s foundation-model approach now exceeds these structural advantages.

4 / 5

Leading AI models such as Microsoft Aurora, DeepMind GraphCast, and ECMWF AIFS trail both HRES and EPT-2 in station-level RMSE and CRPS across wind, temperature, and solar radiation.

5 / 5

Energy traders can run head-to-head benchmarks of HRES, GFS, and EPT-2 on their own regions in minutes. See the impact on your portfolio.
