August 6, 20232 yr Today I did two approaches, one into Santorini LGSR and the other into EGLL (Heathrow). On both approaches winds were at around 40kts below 1000ft. The winds around LGSR were forecast to be around 18kts and those at EGLL around 6kts. I'm using MSFS weather. Is there a bug here?

August 6, 20232 yr Not necessarily... What did the winds aloft look like? Look up a skew-T... Winds can often be significantly stronger just a few hundred feet up, on a breezy day. Andrew Crowley
August 7, 20232 yr Poor blend of metar-winds and meteoblue weather model-winds more likely? Yes there can be a significant difference in wind direction/magnitude between tower reported wind and at 1000ft AGL, but in your case - since it happened on both approaches - I'd say that is an MSFS glitch. As a basic rule of thumb (simplicity of atmospheric model in northern hemisphere) is that the difference between winds at top of friction layer (ca 2000ft AGL) and ground wind is 30 degree veer to the right and 100% increase in speed Ground: 300/10 2000ft: 330/20 But again, this is a basic model, the real world is obviously many times complex and outcomes will not match the model on many occasions.
