However all the scientists, poring over all the data as they do, have tagged all sorts of things to climate change. Snow, frost, rain, fire weather etc. But so far , in Australia at least, not wind. Elsewhere some scientists have tagged an increase in wind and wind energy outputs to climate change.
Speaking from Sandy Point and observing the patterns over the last 40+ years:
There has always been some fluctuation between years, but for the last few years there has been a marked change in the regularity and strength of the summer Easterlies. This is a subjective observation, but the difference is so stark as to be quite obvious.
For the last two years we have also has the strong WSW storms that Sandy Point is notorious for in Spring, fail. Over the years we ran speed events from 2005 to 2013(?), we never failed to get at least a couple of stonking WSW speed days in the fortnight of the last week of September, and the first week of October. For at least the last 5 years, we would have missed out badly. In this period in almost every year there were none, and in the others, if there was one, it was quite weak or brief.
So far for spring 2020 and summer 2021, there seems to be some return to a similar pattern as 10 years ago for the WSW strorms, but the Easterlies are still few and far between.
It appears to my Amateur weather watching eyes that the position and strength of the High pressure systems that pass across southern Australia and the Southern Ocean at this time of the year, has changed over the last half dozen years. It would be interesting if meteorological data comfirms this.
