This has been discussed before, as has the Temperature map.
I certainly admire your passion, But as someone like yourself, from NZ, I guess anything over 30 deg is a heatwave.
Let me reassure you, after having spent 50 + summers in Adelaide.....this summer is no different than many many summers before it.
If you have only been here a few years, then you can be forgiven for panicking.
The last 5-6 years, our summers have been quite mild, this year is back to a more Normal summer pattern.
We have NOT had 48 deg in Adelaide.... The hottest has been about 44.5 Deg., and that is only for 1 hour out of a complete 24 hour day.
The weather you have been experiencing is normal. We Always get very hot northern winds that travel across the vast deserts of Oz, and blow straight
to us. In fact during Really Hot summers, we have Dust storms, which pelts us with red dust....but we havent had one of those for many years.
There have been no more bushfires than normal.....every summer there are bushfires, and more people building homes in bushfire risk areas.....nothing
It is also Normal for us to have Summer rains, as we did last week. In fact last weeks rains we the most we have had for many years.
In the 1960s, I remember many a summer heatwave was broken with summer rains (as per last week), and the bitumen on the roads was so hot, that steam
rose from the wet roads. Have'nt seen that for a while now.
Our hottest months are January and February, so the weather we are having right now, in the mid 20s, is actually cooler than our normal summer
We still have a few more weeks for some more hot weather to come, dont put away the suncream yet.
Dont panic, Australia is not Melting away...this is just a normal summer.
