42.6 is warming up a bit, knocks you around a bit when temps get that high.
I lived up in Mildura, Vic between 1999 & 2007, pretty hot up there, plenty of days over 40, but when we hit 47.5 that was a killer, people were even baking eggs on the footpath to show how hot they were.
Another place I was surprised about was up in Corrying, Vic, up in the high country, winter seen temps down around -7, -8, then in summer we got more than a few days over 40 & up to 45-46.
I was up there when the big fires raged in Vic, it was the black Saturday fires in 2009 & we had 46 up there & the whole area was blanketed in smoke that was blown up from further south, that was a very strange feeling.
Going by the news, we're in for a hot Feb again this year, although I'm in Ballarat now so be lucky to get over 40.
Stay safe everyone & drink plenty of water.
