How Cold is it in Winter in Australia.
That is a question I have seen many times, and the answer always has to be; “It depends on what part”, as it varies so much..
A winter night can be as high as 28°C in one part while it is as low as minus 10°C in another area.
And a Winter day can be as high as 38°C but down to minus 6°C in another part.
These were 2016 figures, 2017 is similar.
