^^^Nice pics looks really dry...even for South West australia.
Pretty hot month so far in Perth average max temperature for the month to date is 34C. Strong and dry offshore winds have been much more dominant than usual, and the usual afternoon seabreeze has failed to materialise most afternoons. More of the same for the next week with strong easterly winds and max temperatures between 32C and 36C, very difficult to keep the veggie garden alive atm
Yeah very stable and above average; very similar to Feb 2015.
Also I'm FIFO these days so I only experience about half of every month weatherwise- for example I actually experienced most of the cooler periods in December which was an otherwise above average month :P .
Southeast Australia is going to experience a light "polar vortex" this weekend with possible snowfall in the alps. You can see the "vortex" brewing in the south:

They're not that rare in the middle of summer. Though the temperatures don't get that low. In the mountains, they would range between -3C to 8C. Here on the coast, they would only go down to 11C-13C at nights.

That's interesting. I thought that with the middle of summer, the monsoon and subtropical ridge would have been farther south, prevent those occurrences.
First Aussie mainland snow of 2021 due later today
If you've just switched on the TV to watch the cricket at a gloriously sun-bathed Gabba in Brisbane, where a maximum of 32 degrees is forecast, you might be surprised by what's brewing in the south of the country.
Melbourne (20ºC), Adelaide (21ºC) and Hobart (17ºC) are all expecting unusually cool maximum temperatures for this time of year. Meanwhile, snow is possible for the high country of New South Wales and Victoria on Friday afternoon or evening, in the first cold outbreak of the new year.
Snow could fall as low as 1500 metres in the Snowy Mountains of NSW and to 1400 metres in the Victorian Alps. Tasmania could also see snow above 1200 metres on Saturday.
Snow is not unusual in Tasmania or the Australian Alps in any month. There are no official statistics on the frequency of summer snowfalls, but anecdotally, you tend to get a few flakes two or three times each summer.
Cold fronts in southern Australia usually push a surge of heat ahead of them. For example on December 1 2020, it snowed down south on a day when Bourke in outback NSW reached 48ºC. And today, Penrith in western Sydney should reach 35ºC.
At other times, cold fronts play a very minor role in our summer weather patterns.
The weather this summer has been largely dominated by La Nina, with persistent cool, cloudy weather from the east which has brought heavy rain to many parts of eastern Australia. A pattern like this tends to push the Southern Ocean cold fronts further south so they don't impact Australia.
So what has changed in the last week?
"During December, unusually high pressure over southern Australia limited the passage of cold fronts over our southern states," Weatherzone meteorologist Ben Domensino explains.
"However this week, we are seeing a stray pool of cold air from the Southern Ocean break through this high pressure ridge and pass over southeastern Australia.
"These cold air masses are more common during winter, although as we are seeing this week, snow can fall in Australia's alps at any time of year, even the middle of summer."
The good news about summer cold outbreaks is that they tend to be quite short-lived.
The snow that falls this evening in NSW and Victoria, and tomorrow in Tasmania, is serious news for alpine hikers and outdoors enthusiasts.
But by Sunday or Monday, things should ease, although the weather should remain cool for summer in much of southeast Australia until at least the middle of next week.

It has now reached southeastern Australia. It's so pleasantly breezy outside, but very clear with temp around 22C and RH of 28%.
That's what I mean, you'd very rarely see such a thing happen in the middle of summer in the Northern Hemisphere subtropics - especially Asia, as well as North America to a lesser extent. A break like that in such a low-latitude is a total unicorn.
