      I use the Meteoblue model the most. I have a lot of faith in their ensemble modelling approach and find it works best for forecasts in the Rockies!

        @Korina For short term forecast, I use HRRR mostly. For longer term forecast I use the ECMWF.

          ECMWF 9km works well in Croatia and I use it most.

            @Korina From the Netherlands I most use models ECMWF and UKM, supported by ICOM.

              Mostly the ECMWF for places all over Europe. If I need a second opinion I like to compare to the ICON models, especially if the high-res covers the area.

                I tend to lean toward ECMWF!

                  In the US, the HRRR 3km model offers the highest resolution in the mesoscale time frame and attempts to resolve wind flow around topography, which is useful for forecasting on wildfires. In the synoptic scale, the ECMWF is my model of choice in the medium range period over the GFS and this past winter, did better at QPF rain and snow amounts.
                  The model comparison feature is a great tool to illustrate model agreement (or not) and identify model outliers.

                    Mostly I use ICON-D2 and ECMWF for Bavaria, Germany.

                      Thank you for all the incredible work in creating such an amazing collection of data and ability to really view the information in so many different ways. As for me, I find the ECMWF to provide the most accurate forecasts for my area (central NH).

                        @Korina I mostly use ECMWF model for near day range forecast, say within week, which gives more accurate direction, momentum, wind data, rain data, also near to my national IMD prediction data. So if for more than 7 day or 15 days or monthly forecast I believe no reason for me to choose specific model.
                        Thanks team for providing such great tool and supports to billions of lives.

                          ECMWF works better for Peloponese and the Corinthian Gulf and generally Greece I think, it's a bit optimistic in terms of precipitation.

                                Thanks for the post! It doesn't tell me a lot of new information, but it's good to know you are actively working on it. :)

                                I'm mostly using the ECMWF model for the Netherlands which seems relatively accurate. In the mountains, I prefer to use ICON-D2 because it works well for areas surrounded by mountains.

                                  For an outdoor sportsman, ECMWF has been remarkably effective in fully explicating the day's current conditions and additionally, correctly predicting the upcoming situation here in the Great Lakes over the long-range period.

                                    I mainly use both ECMWF and ICON, MBLUE rarely and GFS almost never; mostly for paragliding in Romania, Transylvania Area, Cluj-Napoca.

                                    And also the satellite view, quite a lot.

                                      ECMWF, the large european center seems to have fair predictions.

                                        Halo, I'm from Taiwan. I usually most frequently the ECMWF model Forecast, for smaller area its most accurate.

                                          For longer range (i.e. greater than 4-5 days) the ECMWF is usually my go to model, although at times a blend of the GFS with it results in a better forecast. For shorter time ranges, the ICON seems to do well. It would be nice to see the GEM global model in the same data format as the others. For short term, the NAM and HRR add value to forecasts.

                                            Cruising on a 35' sailboat in the SW Pacific, ECMWF is my go-to model. When GFS upgraded, I began compare the two regularly. Very useful in the 5-7 day windows. Even before that upgrade, I would use the compare feature when planning departure windows for ocean passages. Also, the Waves feature is very useful for sailors, most especially comparing wind base to wind gusts - indicating the volatility of the weather system, in addition to the more detailed wave info. Swell period under 9 seconds is very uncomfortable. Thanks for a great Windy!
