What source of weather data Windy use?
The default model of Windy is the model from ECMWF. It is not possible to set another model as default.
@idefix37 Hello ! We use AROME with resolution 0.01° (1.3km). Both of the AROME resolutions have 00, 06, 12 and 18 ref time runs. There are also 03, 09, 15 and 21 ref time runs which we don't process. Advantage of AROME 0.025° (2.5km) is that it includes pressure-level layers. AROME 0.01° provides only surface-level layers, only wind and relative humidity are additionally in 20m, 50m and 100m altitude. However, AROME 0.025° also covers much smaller area - a square that covers whole France and a bit of surrounding area.
It seems that the AROME 0.025 now cover the same area as AROME 0.01. Is there any chance that Windy switch, or add AROME 0.025 to the supported models? The area of new icon D2 is quiet small either. The french paragliding community badly needs the pressure layers on the AROME model

Hello, my first message/question in the community hope no problem to ask such question. Which model you suggest to use in sailing in Turkish Aegean and Mediterranean coasts ? Thanks
@arda-gulcil Hello, I recommend trying all the available models to find the best one for the location.
I would not recommend only one model.
You know there are models providing long-range forecast (up to 10 days) and some short-range forecast (up to 2 days). The first ones have a lower resolution (about 10km or more), the second ones have a higher resolution (about 4km) in your area.
So the first ones are useful to know the weather in the next 5 or 7 days.
In this category I would recommend the ECMWF model, for instance to know if the Meltem wind is predicted to be strong next week.
For medium-range forecast try ICON EU
And for the shorter-range forecast it is better to use NEMS as this Mediterranean area shows a large quantity of mountainous coasts and islands. So you need a high resolution model to get more precision about wind force and direction. Local winds are highly influenced by mountains in the Aegean Sea.
Examples today at same hour
(shown with customized colours for wind):
ECMWF 9km resolution - 10-days range.
The Meltem strength is shown to be fairly even.
ICON 7km resolution - 5-days range
The wind is shown stronger between islands and weaker on leeward coasts.
NEMS 4km resolution - 2.5-days range
The wind is shown even more accurately around islands and capes.
My colour scale for wind is
Blueish green : 4 Beaufort
Bright green : 5 Beaufort
Orange : 6 Beaufort

@TomSlavkovsky why don't you go through the help settings and figure it out.
Why do people say the dumbest thing.
They've got four models they use.
Mind boggles me what's wrong with people
@rkeel61 What are you referring to please?

Hello, I was attempting to utilize your application here in Norway for snowkiting, and water currently in spring/summer. Anyway information utilized in Windyty is exceptionally erroneous for here, all accounts 90% exact.
@john-marshal Hello, what weather model and layer were you using, please?
