      Does anyone know why every time I run a wind speed forecast using a GFS model I get different results?
      I am obtaining the wind speed at 150m at lat=40.05 and lon=-7.68.
      I attach some pictures of the results I am getting.

        @rodrigo-67 Hello, could you please describe what source are you using? Are you comparing it with Windy?

          @korina The green data comes from on-site recorded wind speed measurements, and the orange data is from the windy forecast.

          Every time I request a forecast through the API I got different results. I am using the following parameters for the json body:

          body = {
          "lat": 40.05,
          "lon": -7.68,
          "model": "gfs",
          "parameters": ["wind", "pressure"],
          "levels": ["surface", "150h"],
          "key": api_key
          }

            @rodrigo-67 Hello, we visualize forecast, not real-time data, also the outcome depends may differ based on the model.

            If you are not using the paid version of API, then we the API returns random coordinates.

              @korina Yes I understand. I just wanted to plot measurements (in green) and your forecast (in orange) for future comparison.

              So does that mean that I have to use the paid version of the API to get an accurate forecast? Meaning that with the free version I will get a forecast for random coordinates?
