It's cold here where I live in Oz as well! 3 weeks into summer and the temperature is still only around 70F.
I do live in the southern most state....the one closest to the South Pole ..... and it never gets really hot here.....but......
The northern states have temperatures up in the high 80's, and I'm just waiting patiently for some of those temperatures to start drifting down this way.
