Unsettled weather

Just saying, but the weather in Brisbane in the last couple of weeks has been all over the shop, in a way that I think's quite unusual for this time of year.  We've had a late winter burst of quite cold mornings after some very clear nights, but then it seems out of the blue will come cloud, wind and rain.  Last night it was from an east coast low, which I don't think are very common at all in early August.  Now its sunny and warm again, although maximums are still relatively modest. (Whoops - spoke too soon, it's gone cloudy and breezy again.)

I have been noticing in other recent years that Augusts have not been very cold at night at all - I pay attention to these things because of insisting on sitting and staying at the Ekka for fireworks.  But this year - unless this messy weather all clears up - I am thinking it is going to feel colder there at night, like it used to sometimes be when I went as a child.

Is it all part of global warming causing a more turbulent and changeable mixing of the atmosphere?
