Do you know if the IRM-RMI (meteo.be) have a public API to provide forecast data ?
I seen that some open source application provide data from meteo-france for France which provides much more accurate forecast locally than the global worldwide models. It would be nice to be able to submit a PR with focus on Belgium.
This page seems to give some more information and links to this one (not sure if that’s what you’re looking for, I’m not a programmer).
