@idefix37 I usually compare the forecast with the live data from the cameras in the mountain weather stations - temp and wind and often I see mismatches with all models. Sometimes ECMWF is very accurate, sometimes Icon and sometimes Meteoblue. For example all models today were predicting 85km/h wind gusts top and in reality they reached 110km/h. I know that I want the impossible, after all it is just a prediction. I will consider the data of all models and will have in mind a 20% on top of the predicted wind gusts just in case. Thanks for your help!

@idefix37 Appreciate the reply!

I find Meteoblue to be inaccurate for wind and cloud coverage but I check it for temperature. I will try the observation vs forecast feature for sure.

Hi guys,

I am located in Bulgaria, Eastern Europe and I mostly rely on ECMWF(mainly for cloud coverage and wind) for the mountain weather forecast. I hike a lot in the winter mountain and often spend the night there at altitude 2500/2900m. I've always felt confident with the ECMWF model because for the past 3 years I've compared the forecast with the actual conditions and never had any major surprises. Recently I was unpleasantly surprised by high winds a few times so I also started checking the Icon-EU. My problem is that very often both models shows a big wind amplitude and I am wondering why is it so. I understand that the Icon Eu is more precise but that still doesn't explain the big difference, at least in my opinion. I may be mistaken so any advice will be appreciated.

This is the forecast for Sunday/Monday this week for the exact same location. You can notice the difference in the Wind/Wind Gusts

Hey guys, sorry if this question is answered but I wasn't able to find it here. I am a premium user and rely on Windy for my mountain hikes, especially in Winter.

When I search for a particular location, let's say Vihren peak(2900m) do I also need to adjust the surface level to be 3000m, or when I am checking the wind forecast for a predefined location this is not needed? Basically when do I need to adjust the surface level?

Thanks
