I am not familiar with weather reports in the flight sector but according to German weather service (DWD) it is reported in true north(German source: DWD).

RE: Weather station reports. True or magnetic
Wind direction is defined as the direction from which the wind blows, and is measured clockwise from geographical north, namely, true north (based on the World Geodetic System 1984 (WGS-84) and its Earth Geodetic Model 1996 (EGM96)). - source: WMO
RE: Wind field vs vector and wave forecast
Thanks for your detailed answer, helps a lot. It is good to see that the information is implemented in the UI but is just not visible for me.
I am using iOS 12.1.2 with Windy.com v. 17.05 with an iPhone 5s. My App Store and settings tell me both the App and the OS are updated to their latest versions.
RE: Which model should Windy implement next? Please vote.
Any options to get HIRLAM SKA data? Should significantly improve the resolution. If no I vote 2.
Wind field vs vector and wave forecast
I have two rather simple questions regarding the wind (representation of data) and wave forecast. In the picture below you can see the comparison of wind forecasts at a specific location. As you can see the vector map (showing the ICON data) does not match the ICON wind vector. I am assuming the model output is represented by the vector, while the vector field is just a stylised representation of the data? Or is it using a different time?
In the lower part of the second picture you can see the wave forecast for a specific location. What do the actual rows mean? The first one is obviously wind and gusts (smaller numbers), the third one is wave forecast 1 (Seegang "1"m, 10s). The other two (row two and four) are a miracle to me. What do they mean?
Thanks in advance,
