Interesting that if you make maps of “Maximum Anomaly” and “Minimum Anomaly” for various periods, 1 day and 1 week – then click on the Earlier or Later button – you can see that the heat of September has lessened as we hit mid October.
Also I note both Adelaide and Melbourne have had near average temperatures for October so far.
Canberra wineries hit by coldest October morning ever –
That was on Friday morning 18 October – interesting comments from wineries people.
And of course that record is despite the ever growing Canberra urban heat island.
I am waiting to be able to make anomaly maps.
“Although some cold starts to the day in these parts, other regions of the continent are very warm to hot with many bush fires, as have been in NSW. This does not appear to be in accord, if I remember correctly, with the BoM ‘forecast’ of wetter than average spring!
“If one looks at what the IPCC and modellers say is happening, (in so many words), the atmosphere is warming, the oceans are warming, there should be more water vapour in the air — BUT Australia has been having a succession of droughts or dry spells sufficient to have many damaging bush fires!!
In the 1950s-1960s we had a dry spell with fires followed closely by rain. Or is my memory not that good?
“Any explanation for being so little rain and this continuing weather pattern ?” — Paul
To get a new cold record for October in the second half of the month is something of a freak event, since Canberra’s average minimum rises by nearly 0.1 degrees a day at this time of year – it’s 3.3 degrees in September, 6.1 degrees in October, and 8.8 degrees in November.
Registering such a minimum at the airport after all the years of building out there makes the day even more remarkable.
Of course one freak day does not prove anything. But cold records are more important than heat records in assessing the global warming scare. Both are to be expected if the climate is stable. But cold records should be disappearing if the climate is shifting to a warmer state. If Canberra’s climate was really warming rapidly, whopping cold records like this one wouldn’t be happening.
