There once was a time when Adelong, only 330m above sea level, used to be treated with snowfalls every single year (my town of Corryong likewise-- just not featured much in the old newspaper troves). From time to time 10+ cm falls would occur, which is snowier than most Southeast US places at 35 degree latitudes could comprehend. Wagga Wagga (only 180m above sea level) has received snow about six times from the 1900s to 1960s, whereas nowadays it would be hard-pressed to manage a sleet event. Australia used to be a fairly snowy place far and wide-- far from the stereotype often propagated by tourists and other such foreigners. Even such places as Condobolin (in the 'Outback'), have recorded snowfalls in the past (namely 05 July 1900). Strewth!

Here are the data that show the extraordinary warming trend in July. These data represent the region in and around Tumbarumba in the South West Slopes bioregion: showing a rise of 2 C in the 50 (!) years between the 1938 to 1969 and 1991 to 2020 periods. This equates to a prodigious 4 C per century, which exceeds RCP8.5 by a considerable margin.

Carabost Forest Headquarters (elev. 580m), 1938 to 1969 -- mean max 9.1 C in July



Tumbarumba Post Office (elev. 645m), 1991 to 2020 -- mean max 11.0 C in July



You can't argue with cold, hard data

No they didn't, as these are two different sites about 25km apart (as the crow flies)-- making it impossible to compare minimum temperatures, which are more reliant on topographical inversion as opposed to widespread airmasses. Min temps have also warmed unfortunately.

And it's the same here in the 'deep north'...
Our dry seasons, ie 'winter months' are substantially warmer in the 21st Century compared to the mid to late 20th Century.
These two sites are are only 800m apart, but the newer Middle Point site is warmer during the winter months than the previous site at the Middle Point Ranger's Station site.

Perhaps not, but you can certainly argue with methodology.

Putting methodology aside for the time being though, the cold hard temperature data for Carabost Forest Headquarters were only kept from 1965 to 1969.

Just because the daily data have not been digitised prior to 1965, does not invalidate said data:

Ed, I think you'll find that the published means are for a greater period of records, ie 21 years instead of the full 1938-1969.....usually because there are chunks of missing records, often during the war years.
Seems that only 5 years have been digitised on the Climate Data website.

Thanks, I was wrong. It's 21 years of (partial) data instead of 5. That's still not enough to draw conclusions from. Look at the coverage:

Very nice global cooling here compared to the 1960's .

I can speak for Sydney's winters here. Whilst our nights and early mornings remain typically cool to cold, daytime highs are warm enough for me to wear a T shirt. The highs now are averaging around 19C-20C, a far cry from the classic averages of 17C that were the norm 20 years ago. The past 2 weeks here has been pretty warm for midwinter standards in the afternoon. Seems more like late August/early September type of weather.

This July's average high was close to 20C (19.9C):
