AIFS forecast - AIFS Ensemble Wave
On 12 May 2026, a new forecast stream will be produced by ECMWF's operational Artificial Intelligence Forecasting System ensemble model (AIFS ENS).
The new forecast stream is for wave forecast runs, marking ECMWF's first operational data-driven wave forecasts.
- 4 forecast runs per day (00/06/12/18)
- 6 hourly steps to 360 (15 days)
XIII-i: AIFS forecast
Product description
AIFS forecast - AIFS Single Wave
On 12 May 2026, a new forecast stream will be produced by ECMWF's operational Artificial Intelligence Forecasting System deterministic model (AIFS Single).
The new forecast stream is for wave forecast runs, marking ECMWF's first operational data-driven wave forecasts.
- 4 forecast runs per day (00/06/12/18)
- 6 hourly steps to 360 (15 days)
XII-i: Deterministic AIFS forecast
Product description
AIFS forecast - AIFS Ensemble
Ensemble forecast runs produced by the ECMWF Artificial Intelligence Forecasting System (AIFS) Ensemble model.
- 4 forecast runs per day (00/06/12/18)

X-i: AIFS ENS forecast
Product description
AIFS forecast - AIFS Single
Single forecast runs produced by the ECMWF Artificial Intelligence Forecasting System (AIFS) deterministic model.
AIFS Machine Learning data
ECMWF is now running version 2 of its Artificial Intelligence Forecasting System (AIFS). The AIFS consists of a deterministic model, AIFS Single, and an ensemble model, AIFS ENS.
The deterministic model has been running operationally since 25 February 2025 and was upgraded from AIFS Single v1.1 to AIFS Single v2 on 12 May 2026. Further details can be found on the dedicated Implementation of AIFS Single v1 page.
