Minus 7.2 is the coldest daily min for June at Canberra Airport since 1986
I have not found that the ABC www has reported this.
It flies in the face of what BoM said on 1st June.
The Bureau forecasts warmer and drier winter conditions for much of Australia 01/06/2023

I notice Weatherzone skillfully confuses the issue with any month.
Ben Domensino, 21 June 2023, – Coldest morning in 5 years for parts of NSW, QLD, ACT

The minus 7.2 flies in the face of the ever increasing Canberra urban heat island – just checkout recent developments near Canberra Airport.
Does not exactly back the warming meme that demands we commit to NetZero by whenever.
Much official obfuscation going on.
The ABC has a story on it now, diverting, misleading, as usual.
Temperature records broken across NSW due to consecutive cold fronts, according to BOM 21June23
www.abc.net.au/news/2023-06-21/june-temperature-records-broken/102505184
Quote [Meteorologist Helen Reid said the cold temperatures were due to a compounding effect after a series of small cold fronts.
“Quite often between cold fronts you have time for the air temperature to get a bit warmer again,” she said.
“But on these occasions we haven’t so we’ve just had cold air followed by more cold air.
“When those systems have gone through the wind settles down and the air with it is also very dry, it helps everything cool down even further.”
Coldest June morning
Several locations across regional NSW experienced their coldest June morning on record:
Bathurst: -7.5 degrees, records going back 33 years
Hillston: -4 degrees, records going back 64 years
Peak Hill: -2.8 degrees, records going back 56 years
Paterson: -0.3 degrees, records going back 54 years
The bureau had earlier thought Richmond, north-west of Sydney, had set a record of -6.2 degrees, but the data is now being reviewed after some discrepancies were identified.
Cold in Canberra, other states stay warm
Ms Reid said Canberra Airport set a June record of -7.2 degrees, but the data there only dates back 15 years.
Climatologists typically use 30 years of records as the benchmark for determining if a record has been set.
“It’s possibly in the honourable mention category for the Canberra Airport,” Ms Reid said.]
As usual when some event is noted as the “coldest, or hottest, or wettest, or driest, or just the mostest since the year blankety dot dot”, the BoM is just not asked what the atmospheric CO2 concentration was then.
If the MSM ever breaks its’ mould of magic and asks that question, obfuscation will be too mild to describe the panic to find an answer that avoids the point.
Almost an all time June record for Lithgow.
The site Marrangaroo (Defence) has June records back to only 2018 but it got down to -9.6. Prior record was -7.8
The Lithgow (Cooerwull) site got down to -7.2
I say almost because the older part of the longer record is not digitised. an out of town record gives a clue to a colder day. Lithgow (Birdwood St) has a lowest June in the digitised, part from 1966 to 2006 of -7.
A bit further out of town the old Lidsdale State Forest site from 1965 to 1974 has a lowest June day of -8. On the same day June 19, 1974 the Birdwood St site has -4.5. they both have -7 on June 27 1974. Further out of town again there is a day that looks to have been colder at Lithgow (Newnes Forest Centre) -7.8 on 1965. The temperatures for 1974 are warmer there. The 19th at -1.5 and the 27th at -0.5.
Not sure how you claim this is an error. It’s the data. Predictions of changes in climate over years are not related to a specific spot location at a specific time. About all you can say is that the local variation for weather is likely within the standard deviation expected climatically for that region for that season. This was an outlier, so likely was 2-3 standard deviations from expected – and the cause is well understood (and detailed in other comments).
It really doesn’t matter if a specific time/place was colder or hotter in the past. We always will have hotter and colder days, or hours. What matters is the trend over time. Decades and centuries.
Also see polar vortexes. Occur both in the north, and less often (but with rising frequency), in the south.
CO2 is well mixed, and concentrations barely change intraday, so that’s not important or relevant. The trend is upwards by 3-4ppm per year globally, and there’s a slight (largely predictable) seasonal variation through a year. That’s about it. Atmospherically it doesn’t have a strongly varied localised impact.
