When I look at the forecast, I read it (for example) as "Later today the will will increase by 20% and turn more North." When read this way, the results of all the models are very accurate and much better than "At 2pm the wind will be 24kts from 300 degrees."

The former is plenty useful for planning and knowing what to expect. The later will leave you frustrated when it isn't exactly perfect.

The only thing that is accurate in a weather forecast is the date!

Witch current model do you used? Is one more accurate?

I use both Windy (premium) and PredictWind (standard).
Interesting comments from the Windy app about the diffent models:

ECMWF:
ECMWF 9km
Very accurate model provided by the European Centre for Medium-Range Weather Forecasts. Clear winner compared to other forecast models. Since the model is commercial, only a few companies in the World offer it.

GFS:
GFS 22km
Basic free model provided by National Oceanic and Atmospheric Administration (NOAA) with not so good resolution. Compared to other models GFS can fail in mountain areas, and by forecasting clouds and precipitation. Since the model is free, majority of weather applications use GFS.

ACCESS:
ACCESS-G3 12km
Australian Community Climate and Earth-System Simulator (ACCESS). Based upon the UK Met Office Unified Model system. ACCESS G3 is the global numerical forecast model operated by the BoM. It is run four times daily and provides forecast data out to 240 hours with a horizontal resolution of approximately 12km and 70 vertical levels.
