      https://www.windy.com/?gfs,38.284,-37.430,8,i:pressure,m:eJNae6w

      Your above URL works for me and immediately displays the marker.

      Please note that after the page loads the url changes.

      In general, load the page and all info / layers that you want, with correct zoom level, etc, and after click in the location you want to add the marker. Then copy the URL.

      Careful checking of the URL shows which parts load different info.

      If you want a very accurate location (eg: your house) you can also use the same method in the opposite way:

      zoom all the way in, click on your house to show the marker, then zoom out, set layers, etc, and after copy the url.

      Hope this helps :)

      WINDY is everywhere :)

        geohash type of system.

        Seems to be alphanumeric: starting bcd...z, A...Z, 0....8 (thus base 60), increments of 0.01 degree. Starting lat -90 and lon -180.

        there is an "a" between the lat and lon.

            @jmh2002 It is for a boat that sails so I have to create the "geohash" according to lat, lon

                JS function for you:

                function createCoordCode(coords){
                    let ar=[];
                    for (let i=98; i < 123; i++) ar.push(String.fromCharCode(i));
                    for (let i=65; i < 91; i++) ar.push(String.fromCharCode(i));
                    for (let i=0; i < 9; i++) ar.push(i);
                
                    let lat=Math.round(100*(coords.lat+90));
                    let lon=Math.round(100*(coords.lon+180));
                
                    lt1=Math.floor(lat/3600);
                    lt2=Math.floor((lat-lt1*3600)/60);
                    lt3=lat-lt1*3600-lt2*60;
                
                    ln1=Math.floor(lon/3600);
                    ln2=Math.floor((lon-ln1*3600)/60);
                    ln3=lon-ln1*3600-ln2*60;
                
                    return "m:"+ar[lt1]+ar[lt2]+ar[lt3]+"a"+ar[ln1]+ar[ln2]+ar[ln3];
                }
                
                console.log(createCoordCode({lat:-29,lon:100}));

                    I have a shift of 7 second North and 11 second West between the real position and Windy position.
                    What should I correct in your code to obtain an identical position?
                    Thanks again for the code, it's cool 😉

                      That happens, because the max resolution of the alphanum code is 0.01deg, thus 36 seconds (about 1km).

                      made code a bit shorter:

                      function createCoordCode(coords){
                          let ar=[];
                          for (let i=98;i < 123;i++)ar.push(String.fromCharCode(i));
                          for (let i=65;i < 91;i++)ar.push(String.fromCharCode(i));
                          for (let i=0;i < 9;i++)ar.push(i);
                      
                          let lat=Math.round(100*(coords.lat+90));
                          let lon=Math.round(100*(coords.lon+180));
                      
                          return "m:"
                                  +ar[Math.floor(lat/3600)]
                                  +ar[Math.floor((lat%3600)/60)]
                                  +ar[lat%60]+"a"
                                  +ar[Math.floor(lon/3600)]
                                  +ar[Math.floor((lon%3600)/60)]
                                  +ar[lon%60];
                      }
                      console.log(createCoordCode({lat:38,lon:-30}));

                            Hi, guys we will give the option to share the picker in URL. It will be possible very soon by adding d:picker` into the URL.

                              will you share the info here when it's possible?
                              Thanks 😉

                                @GeGaX @rittels It's now possible to open Windy with picker.

                                Also recommend to check following topic: https://community.windy.com/topic/77/windy-com-url-parameters

                                  Thanks for this improvement, it works very well ;)
                                  The GPS coordinates displayed, by the picker, are translated exactly as those sent despite the truncated display in the address bar, it's perfect !

                                  @rittels
                                  Thanks again for the JS code which has helped me well until here.
                                  (And in addition I discovered the GeoHash system ;p)

                                    Cool. Thanks!! Works well.

                                    Can we mount plugins yet? I see we can open an airport from path.
