      I rely mostly on the ECMWF, but now will look more closely at the HRRR and NAM for the the US west coast.

        @Korina my wife and I have learned to trust and sail by the ECMWF Model as we live and travel aboard our Sailing Catamaran along the East Coast of the US & Canada, along with the Bahamas. We've discovered the hard way, that the Gust Forecast is often the sustained conditions that we find offshore. Thus the Windy App is a constant in our life onboard.

          I primarily use ECMWF, but really appreciate the ability to compare multiple forecasts to get a sense of which is most accurate for wherever I happen to be.

            @Korina Hi, love the app and use it sailing the East Coast of Australia. I like to refer to both ECMWF and GFS and this has been very reliable. Cheers for a great product.

                For us, here in Greece, ECMWF does its magic quite good. It is a little more sensitive than usual in the sense that it predicts rainfall when the rainy clouds above retain the raindrops and don't release them to the ground but you cannot say that they don't exist!

                    Over the past few years I have sailed from New york to Alaska. I use the ECMWF most, but usually compare with GFS. I became a premium member early on because I want to support the BEST!

                      I'm using ECMWF as my preferred model.

                        I'm finding for mountains in NE US, the NAM model is usually most accurate. In coastal areas I like ECWMF.

                          @Korina Most reliable PWE/PWA
                          For me sailing in Southeast Brazil, mostly in Rio de Janeiro/ São Paulo

                            @Korina I find the ECMWF model to be most consistent and reliable in the middle of Kansas where I live. Variability between the models tells me to keep my eyes out for upcoming changes in the forecast.

                                @Korina I think ECMWF are more relible and give right information maximum.

                                  I use the compare all. It gives the most accurate by viewing all of them to know exactly what will occur. It’s been the best weather tool for my line of work.

                                      ECMWF is best suited for our region

                                        @Korina here in Montague County, TX, I start with ECMWF as default, then HRRR as at least one of the local TV stations in Wichita Falls (closest major town ~60 miles away) uses it. Comparing multiple is useful as you’ve indicated

                                          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.
