Anybody know what the forecasts were for Sunday and Monday?
BoM have not settled on a max for Monday yet.
May be the BOM has not settled on a Max but their records show it was 14.1 Celsius at 5:32 PM and it was the highest for the day. I live in Canberra it was 12°C at midday.
This afternoon BoM entered the 15.1 – I had seen that yesterday in their High Temp column logged at 5.34pm – I kept a screen save.
But here it is here more official now.

for sure a chilly day for time of year. And – unusual for the daily max to click in after half past five.
Upper Blue Mountains yesterday Tuesday Dec 3 at 8am:
Temperature 6C, wind chill -7C, a net of -1C.
It’s pleasing to see the seasons folowing the Gregorian calendar to the day.
Warwick,
In the news today, Perth had its earliest hottest December day, yesterday (41.6), as posted on the BoM webpage for PerthMetro.
So, I decided to look at the Perth historical temperature record at the BoM climate page. Consequently, I downloaded 2 historical graphs, from Perth Regional and Metro stations (see draft figure below). I note on the website, waclimate.net, the author states:
“Perth temperature history
Perth’s temperature history began in 1897 atop Mt Eliza (elevation 61m) with the establishment by the Bureau of Meteorology of weather station 9034 (Perth Regional Office).
In 1963 the station was moved about 300m and in 1967 it was relocated about two kilometres to inner city Wellington St, East Perth (elevation 19m). Station 9034 closed in 1992 and the Stevenson Screen thermometer was moved four kilometres north to establish the Perth Metro station in Mt Lawley (9225, elevation 24.9m), with the 9034 historic record adjusted for baseline equivalence for both the Perth Metro and Perth Airport stations.”
The author has done an in depth analysis of the Perth record, so I don’t pretend to be adding anything new.
But maybe you could comment on what the baseline adjustments, as mentioned above, do to the BoM data. Is this part of the ‘homogenisation’ process? And is the Urban Heat effect taken into account?
Cheers and thanks for your informative website.

waclimate.net has this useful page on the various sites for the Perth thermometers since 1897.
If you scroll down about half way – see the map showing Observatory and Wellington St as red dots.
The 3rd chart under that shows annual min-mean-max with the site changes marked.
It makes sense to me that Wellington St was the most central urban site and interesting that Metro reflects the cooler mean t in parkland but is still urban affected as urbanization extends for huge areas in all directions.
These GISS diagrams illustrate how steps such as the start of Metro are best left “as is” and not “adjusted to join” which as GISS shows cements UHI into the time series.
Thanks Warwick, I will have a look at those links. I have seen a Melbourne UHI profile ,and for Sydney, there is a general UHI map which shows 3-6 degrees of UHI effect at Observatory Hill posted on the NSW Gov website. I compared the temperature readings at Observatory Hill with those at Wedding Cake Island (located on a buoy in Sydney Harbour, about 7 kilometres to the east, near Clifton Gardens). The harbour station temperatures (from 1997-present) are regularly about 3.5 degrees lower than the city located Observatory Hill readings. Much has been written about Observatory Hill on location, environmental and equipment changes. This has been covered on Joanne Nova’s blog in the past. BTW, assuming you live in Perth, are you going to Jo Nova’s Christmas dinner (venue to be announced) to be held this Friday? Cheers, JB
Seems Monday 2nd December 2019 saw an Australian summer record low daily max of minus 1 degree for Australia at Thredbo Top Station. All over media.
So say weatherzone.
and here is Thredbo Top Station
Hi Beachgirl, There seems to be an error with your first link, which is not to weatherzone. Cheers.
Gidday Dave – fixed now – I think Beachgirl is keen on early model Ford Falcons.
Thanks wazz and it’s a good story. Blames the record cold on a “sudden stratospheric warming episode” and finishes with:
“The complex sequence of events that caused southeastern Australia’s cold start to summer are well understood. However, the impact of climate change on sudden stratospheric warming episodes in the southern hemisphere are not and this is still an active area of research.”
So now they get research dollars to figure out how “climate change” causes record cold summer days…
I was pricing XF tail lights and pasted the wrong link; palm meets head. I saw a last Mondays newspaper today and the Canberra forecast was 14 so they had the cold day well taped.
