This forum is discussion platform for users of ECMWF’s forecasts to interact with other users and ECMWF experts, and post comments on topics of interest related to weather and forecasts, and to provide feedback to ECMWF.  

Within the forecast user forum space, we have three forum categories: current and recent weather (please note ECMWF cannot provide any guidance on model output related to ongoing weather events), featured feedback topics where forecast users can provide feedback on current topics of interest related to forecast products and performance, and UEF events and training

ECMWF are always interested in the experiences and feedback of our forecast users. We will be monitoring these forum discussions, joining the conversations and considering feedback and comments in our ongoing research and diagnostic work, but we cannot guarantee a response to every topic or question.  If your comment or question requires a direct response from ECMWF staff, please head to the ECMWF support portal to contact the relevant department. 

This forum is not designed to provide answers to technical questions regarding the access to and use of ECMWF forecasts and data. For questions of this nature, please visit the ECMWF support portal for more information or to contact someone who can help with your query.  

For users of OpenIFS, and the Copernicus C3S and CAMS services, you may also be interested in the OpenIFS User Forums and Copernicus User Support Forum
