Thank you for this article and for the work behind Open-Meteo.
I’m using Open-Meteo as the main data source for CLIMA TERRA, a free educational climate experience created to help non-technical users better understand weather and climate-related data in a clear and simple way.
The Single Runs API presented in this article is very interesting because it makes it possible to look at a specific model run and understand what a forecast was predicting at a given moment. From an educational point of view, this could be very useful in the future to explain forecast uncertainty and how weather predictions evolve as new data becomes available.
The fact that Open-Meteo is accessible, open and free to use makes a real difference. It allows projects like CLIMA TERRA to remain free as well, while still offering useful climate and weather information to the public.
For now, CLIMA TERRA remains lightweight and focused on simple interpretation, but Open-Meteo is an essential part of making this kind of project possible.
Thank you again for making weather data so accessible.
Hi Patrick, Currently interning as an R&D Data Scientist, I’ve created an account and am reaching out to you on the advice of my supervisor. First of all, a huge thank you for Open-Meteo's Single Runs API, which I am currently working with. It's tool that greatly simplifies the development of new models and technologies. It's really great of you to make all of this so accessible! My request is regarding the AROME forecast models for a day-ahead horizon. Some time ago, it seemed that the data for these models was available going back to September 2025. However, I’ve noticed that the accessible history now only starts from this past April. Do you know if there is a way or an alternative to retrieve the forecasts for these models from September 2025 (or even earlier), even if they are not currently accessible directly through the API? This would be of great help for my research. Thanks in advance for your help! Best regards, Barthélémy
Hi, to my knowledge there are no MeteoFrance AROME easily archives accessible. The France open data server deleted AROME forecasts after a couple of days. The MeteoFrance API Portal might have some more data, but i havent checked: https://portail-api.meteofrance.fr/web/
very interesting and useful API!
