Question 1

What weather models does MeteoModels compare?

Accepted Answer

MeteoModels compares up to 13 numerical weather prediction (NWP) models: GFS (NOAA, USA), ECMWF IFS (European Centre), ICON Global and ICON EU (DWD, Germany), HRRR (NOAA, 3 km resolution for the continental USA), AROME HD and AROME 2.5 km (Météo-France, France), ARPEGE EU (Météo-France), MeteoBlue (Switzerland), UKMO (UK Met Office), GEM (Environment Canada), KNMI HARMONIE (Netherlands, NW Europe) and DMI HARMONIE (Denmark, N Europe).

Question 2

Is MeteoModels free to use?

Accepted Answer

Yes. MeteoModels is completely free, requires no account or registration, and works in any modern browser. It can also be installed as a Progressive Web App (PWA) for offline use on any device.

Question 3

What is the difference between MeteoModels and a regular weather app?

Accepted Answer

Most weather apps show a single forecast from one model. MeteoModels shows all major models simultaneously with a weighted ensemble average. You can see where models agree (high confidence) and where they diverge (uncertain forecast) — essential information for planning around borderline or severe weather.

Question 4

How does MeteoModels weight weather models?

Accepted Answer

Each model receives a base accuracy score, a regional bonus (higher for high-resolution regional models covering your area, such as AROME for France or HRRR for the USA), a resolution bonus (finer grid resolution means better terrain capture), and a terrain sensitivity modifier for complex orography. Weights are normalised to 100% and used to compute the ensemble average shown as the main forecast.

Question 5

How does MeteoModels detect rain in real time?

Accepted Answer

MeteoModels queries all active personal weather stations (PWS) from Weather Underground within 2 km of your location via the /api/observation endpoint. The station_rain flag is true if any station reports a precipitation rate above zero mm/h in an observation less than 15 minutes old. A rain_confidence score (0.0 to 1.0) shows the fraction of nearby stations confirming rain, providing a multi-station consensus.

Question 6

Does MeteoModels work offline?

Accepted Answer

Yes. MeteoModels is a Progressive Web App (PWA). After the first load, the app shell and recently viewed forecasts are cached locally so you can open the app without an internet connection.

Question 7

Which languages does MeteoModels support?

Accepted Answer

MeteoModels is available in Catalan, Spanish, English, French and German. The language can be changed at any time using the language selector in the top-right corner of the app.
