      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!

        I use the ECMWF for long range, then the GFS for 3 days out. For a daily look a head is use the HRRR. I do like how all the models are in one place on windy.

          @Korina here in the middle of the US, I tend to rely on GFS, but I am often startled by how different the 3 US National Weather Service models (GFS, NAM, HRRR) are.

            Meteoblue is most accurate for the mountains of the Kenai Peninsula in Alaska during the winter.

                  I work in the cruise industy Sailing all over the world, I mainly use the ECMWF model on a daily basis and compare it with others sources and models, so far the ECMWF has been the most effecient and acurate in all my weather analysis forecast. Besides the route planner (with Premium) helps me to get a better understanding of the backing and veering of the wind direction for a better ships planning operation.

                    Hi All, sailing all year round in the mediterránea, I'm comparing both ECMWF and Arome. ECMWF for the short and mid range forecasts and Arome for short passage 12-24h with this more precise forecast model 1.3km but only 24-36h window and bearing in mind the specificities when closer to the coasts. I used to sail in Ireland too for many years and both forecast models seem to be the most reliable too.

                      Hi, @Korina

                      My most used weather model in Canary Islands (NW Africa - Spain) is ECMWF.

                      Best Wishes 😊🌤️

                        East Med, I use ECMWF mostly. In springtime however all the models are less reliable, so I'm usually on the Compare Feature :)

                          The ECMWF seems to be the most accurate for my locale, but having the ability to compare the different models gives me more overall confidence in any given forecast. and, they are just that - forecasts, not guarantees.

                            I mostly use ECMWF for kitesurfing/sailing, METEOBLUE for snowborading/trekking and GFS for motorcycling! :)

                              ECMWF for sailing in seas around Europe (Greece, Croatia, Baltics)

                                I use ECMWF because it's very reliable, but i also use ICON-D2 when i need more input. ICON has high resolution which makes for a nice comparison between the two. Unfortunately, D2 only has a 1.5 day forecast.

                                  It depends by the area: might be MBLUE more reliable than ECMWF or the other way around

                                    The most accurate model for me in Japan has been the ECMWF for daily weather and GFS for the movement of Tropical Systems.

                                      I usually use ECMWF models in Taiwan.

                                        I use in northern Germany ECMWF.

                                          I mostly compare ECMWF,, ICON and GFS and take "average" of forecast. Overall GFS seems to give more extreme numbers (max/min temperatures, precipitations etc.). From the point of view of the resulting success, it is different, and comparing forecasts is therefore a perfect opportunity to get a more accurate idea for the given moment. Mostly used location - Czech republic, Přerov,. Thanks for your work! Pavel

                                            In the Med, I use a combination of ECMWF and ICON-EU
