Autumn now.
US after summer equivalent 18th September.

@swirlie In my case (and I admit we dont get the long runs of heat Perth do) As long as you have A/C and can sleep at night, you can cope with the heat for short bursts. Of course, the garden is burned to a crisp, unless you chose drought tolerant plants. I have an oak tree in my front yard I planted as an acorn a long time ago. I went out yesterday, after a couple of warm days and the thing has dumped every acorn at once in protest.😷

I was reading where pine trees in Australia are a different species of pine than are found up here.
A pine tree will suddenly drop all of it's pine cones if it senses it's own impending mortality from environmental factors, or if it is experiencing severe drought conditions where again it senses it's lifetime passing before it's eyes.
I suspect an oak tree thinks the same way as a pine. The fact that acorns and pine cones will all get dropped by those trees would tell us how close to a non-survivable environment that we all are living in.

@swirlie Possibly. Pine plantations here are subject to bushfires and some tree species actually "sweat" volatile oils at high temperatures, resulting in a "Crown fire" that can race through the tree tops faster than a person can flee. I have no idea how my oak has evolved. I know they werent in this country before 1770. So I cant imagine much evolution has happened.😷

Most likely your oak tree was taken there specifically to grow by some human oak tree trafficker back in the day.
I know that back in the 1400s, it was common for explorers to bring small seedlings of trees from one Caribbean island to another or from more northerly latitudes to other similar latitudes, which is how a lot of tree species got displaced from their natural habitat.
The Canadian sugar maple tree for example, grows abundantly in the American mid-latitudes, though that species is not indigenous to the USA at all.
In fact the sugar maple tree isn't typically found growing in even modest forestation in the very most southerly latitudes of southern Ontario Canada, though they are common to see all the time where I am here.
The sugar maple that grows in the USA is the same species that grows up north in Canada, but it doesn't produce maple syrup sap like that found in Canada, nor does it make good hardwood lumber.
The reason for that is the sugar maple requires deep freezing temperatures during winter to survive properly, which of course isn't typically found in the mid-latitudes of the USA.
Without that deep freeze, the sap contains very little sugar content and the wood turns soft, making it more of a softwood variety in the USA than a hardwood variety in Canada.
Also, if a deep freeze suddenly hits the American mid-latitudes, those Canadian sugar maple trees will often split wide open when the sap freezes inside the trunk.
During winter, a sugar maple stores it's sap in it's root system, not in it's trunk. But if it doesn't get cold in winter where it is growing in the USA, the sap will remain dispersed throughout the tree trunk and limbs.
If a sudden deep-freeze occurs overnight, that tree turns into instant firewood as every limb and every part of the trunk split wide open from the expanding sap as it freezes solid inside the tree.

@swirlie Actually, I picked up a dozen acorns from a grove of oaks at the university where I worked and potted them. They nearly all took and I picked the best looking one when they were a foot high. I figure the parent tree goes back to about 1960 when the Uni was first established.😷

@swirlie Noel Coward sang, "Only mad dogs and English men go out in the midday sun"
Sensible people such as Gusman seek shade until the sun has lowered beyond the horizon.
When I first arrived in Western Australia, I was astounded to see council workers digging with shovels when the temperature was hovering around the 100-degree mark.
Cricketers out on the oval with the temperature above 105 degrees.
So, it is not only mad dogs and Englishmen, but some also pretty crazy Aussies do it as well.

Funny you say that because where I was born and raised in southern Ontario Canada along Lake Erie, my parents raised my sisters and I on a tobacco farm.
We had migrant farm workers come up from Kingston Jamaica each year whom my father hired to come and plant the crops and do the harvest as well, but when the daytime morning temp reached 25C, all field labor stopped by 11am and didn't resume again until 3pm that afternoon.
