Mean daily wind speed at Belmullet for the winter period:
Clearly a peak in the late 80s through the 90s, before falling back down again.
Max winter gust speeds, less obvious, but a clear decline in the frequency of very high gusts (>=40 m/s) at the station since the 'naughties'.
Just looking at those excelling photos that GL posted, exposure does not seem to be an issue at the Claremorris station. As I said earlier, we can reasonably check and compare Claremorris wind data against that of Athenry as there is usually not much of a difference in max gust speeds during notable events, though of course there will be exceptions.
Data from the ECA&D.
