# Open Meteo Models

The Jua platform provides access to a selection of weather models served through [Open Meteo](https://open-meteo.com/en/docs/), a third-party weather data aggregator. These models cover global and regional forecasts from multiple providers including ECMWF, NOAA/NCEP, DWD, KNMI, Météo-France, and UKMO.

## Limitations

Open Meteo models have the following restrictions compared to natively ingested models:

* **Latest forecast only** — only the most recent forecast run is available. Historical forecasts are not supported.
* **Point queries only** — regional and grid-based queries are not supported.
* **No streaming** — streaming responses are not available for Open Meteo models.
