But the BoM fails to say that outside the Hobart urban heat island (UHI) record warmth is harder to find.
I checked the following stations around the Hobart region – first the mean monthly max – only Tasman Island agreed with Hobart but the site has only operated from 2002.
then the mean monthly min gives a similar result.
So the BoM should have told the ABC that although central Hobart had a record warm October – few other sites in the district confirmed that so on balance you would assume that the UHI effect has been quietly ramping up warmth in Hobart data for a ~century.

Australian BoM October rain Outlook disaster
Could have done better – miniscule areas with above average rain predicted but it looks as if about half of the misgoverned nation enjoyed over average rain. And they get Tasmania exactly wrong.
October max(daytime) temperatures were forecast to be high in most of the coastal rim and cool in the centre extending to the SW. Reality was that pattern was nothing like that with a fail along the coastal half of Qld and many central failed areas. I wonder who benefits from these Outlooks – anybody out there hangs out for them?
October min(night) temperatures were forecast to be a bit cooler than the days with a similar shape. Reality was the peak hot nights were nowhere near where they were predicted but there were some small wins in the cool areas. Again I wonder who benefits from these Outlooks.
Lets check the BoM 3 Month Outlooks – first rain – OK I think it shows not one square centimetre of Australia was due for above average rain. But reality was that vast areas of Australia had above average rain. Monster fail.
Now Max (daytime) temperature – I think it shows not one square centimetre of Australia was due for average or below average temperatures. But reality was that large areas of Australia from Carnarvon-Southern Vic- Tasmania and FNQ coast experienced near average or very mildly warm temperatures . And nowhere in the rest of Australia did the scale of temperature anomalies reach the extreme level of the predictions. Fail.
Now Min (night) temperatures. Not one square centimetre of Australia was due for average or below average night temperatures. Yet in the real world large areas were either anomalously cool or only very mildy warm. Big fail here.
