Having operated there for many years, I can report the winds are, indeed, "fickle". But give me FNC any day over any of the Alpine airports with the go-round towards the mountains.
And if you look at the actuals in the Av Herald reporthttp://avherald.com/h?article=47025f64&opt=0 you will see the Rosario wind is very different to the 05 etc etc…. As I said previously, when all the windsocks point in different directions, it's time to tread very carefully.
I have to say though ATC are usually very good at letting you know they think you should bugger off, and in my experience, the wind is never on the dividing line on the chart diagram and they make it clear when it's out of limits.
