Others may know more about live traffic, but from what I understand, it’s just the flight plans that are in the sim, not the actual tracks. So if in sim, the wind direction is different than the current real-world direction, it makes sense that planes could land on the opposite runway.
There are other threads in the forum describing how “Live Weather” is not exactly what is being experienced in the world but more of a prediction model that is close to real. I know that is not what simmers would prefer, but I think that’s as good as it will get considering that it’s not feasible to get super accurate real world weather data across the entire globe.
