Weather API Accuracy Comparison Europe: Verified Rankings

1 / 5

Inaccurate weather forecasts cost European energy traders millions each year. A 1 GW wind portfolio gains about €1.5 million annually from a four‑percentage‑point accuracy improvement.

2 / 5

EPT-2 (Jua for Energy) ranks first on RMSE across 10 m wind, 100 m wind, 2 m temperature, and surface solar radiation at every lead time from 0–240 hours, ahead of ECMWF HRES and Microsoft Aurora.

3 / 5

StationBench verification against more than 10,000 real European ground stations shows EPT-2e beats the 50-member ECMWF ENS mean on both RMSE and CRPS with only 10 ensemble members.

4 / 5

EPT-2 updates up to 24 times per day with 5 km resolution and a 2.5-hour dissemination advantage, so traders can reposition intraday faster than desks relying on traditional NWP cycles.
