Weather models and updating frequency

Yr.no generates weather forecasts for millions of places around the world. Its 3-day forecast uses two different weather models with a 2.5 km resolution in Scandinavia and the Norwegian islands, and for other places, the ECMWF's IFS model in high-resolution configuration (HRES), with a 9 km resolution.[3]

For the 10 day forecast, yr.no employs the ECMWF-ENS model with an 18 km resolution for Norwegian territories, and for the rest of the world, IFS-HRES with a 9 km resolution.[3]

Outside of Scandinavia, the 3-day forecasts are updated every six hours, and the 10-day forecasts every 12 hours.[4]
