In the south of Western Australia we had a regular wind arriving each day about noon and we called it the 'Fremantle Doctor' because after a morning of blistering heat the relief we felt with that wind was a tonic.
On the days when it never arrives, usually in mid summer, the heat can be so oppressive.
I must mention that I don't live in Australia anymore. I now live in the Wirral, UK. and the bitter north winds make my eyes water, but by wrapping up I can keep warm not like in Australia where I couldn't keep cool apart from sitting all day in the shopping centers.
Tanny.
