Explanatory notes:

Perth had seen 6 consecutive days with a maximum temperature above 40°C which is the longest 40+°C spell on record for any month, beating the previous record of 4 consecutive days in February 1933, February 2016 and December 2021 by a margin. Prior to December 2021, Perth has not seen 4 or more consecutive 40+°C outside of December.

It is in fact the longest 40°C spell on record for any Australian capital city, drawing with Adelaide, with records going back to the 19th century.

6 40+°C days in total in a calendar month is also the record highest beating the previous record of 5 days just set in December 2021.

Perth has seen 11 40+°C days this summer so far, breaking the previous record for the entire summer of 7 by a large margin and summer is far from over.

The heatwave was due to a hot air mass and the west coast trough lingering over the region with subsidence heating below an upper level anticyclone aloft. Climate change was also very likely to have been a necessary causal factor.

Some respite until tomorrow as cooler air had moved in from the southeast, still hot days but much less hot and cooler nights with cool air advection from the southeast.

Becoming very hot again towards the weekend as the west coast trough deepens off the west coast, also the slight possibility of convection with steep vertical lapse rates, most likely over the hills.
