      On the Chesapeake Bay near Annapolis, I use the compare models for 3-5 day and HRRR for 12‐24hrs. Fantastic app! Thank you for the 1 hour update! On the Bay, it makes a difference when timing with the currents and tides.

        I use the ecmwf and gfs models for looking at wind. I use the ecmwf for looking at shorter period swells from multiple directions and then only use the gfs when theres a big long period swell. The gfs tends to filter out many little swells, but sometimes its good to know about all the little swells.

              I find ECMWF most accurate for the western Baltic Sea

                        Hi Korina.
                        I work on the Manly ferry service in Sydney Australia and use Windy extensively to see wind and swell forecasts.
                        I've set up a favourites point between the harbour entrance ,where swells may reach over 5m in bad conditions.
                        I particularly like the ability to switch between models to check consistency. Also the display of wind and isobars is first class.

                        Locally some people use a near shore forecast model which is based, I think, on NOAA 3. Do you know if , in broad terms this is similar to GFS?

                        Finally, given the forecast models have a resolution of several km : When looking at points close together ; are the differences explained by interpolation?

                        Great program, keep up the good work.

                          In Poland I use ECMWF most of the time (and comparison feature when I need more understanding and confidence).

                            Guys,you are the best! For me, Ecmwf stands out here in NE Italy. Thanks again for your efforts and dedication

                              ECWMF for east coast of Australia and South Pacific wins hands down.

                                I use the Meteoblue as this is the most accurate for the location where I live. Living in a small alpine valley in Austria right to the main ridge of the alps forecast can be tricky. Especially temperature forecasts are very different between the models most of the time.

                                  @Korina the ECMWF is what I predominantly use especially for my PPG flying here in South Africa πŸ‡ΏπŸ‡¦

                                    In my country, Oman, ICON then ECMWF are working perfectly.

                                      @Korina Hello I tend to trust more the GFS and mΓ©tΓ©o blue model.
                                      The fact that we can easily compare the different model is great feature. Thanks for that! Nice cap by the way...

                                        @Korina ECWMF works good for me in central Germany - occasionally I take a look at the comparison. πŸ‘πŸ™‚

                                          @Korina On the east coast of Australia, at least between Hobart and Sydney, the ECMWF consistently underestimates the wind speed (being used for sailing) by 5 to 10 knots. This is a large discrepancy for a sailboat. The Access 12 model does a much better job.
