Western Australia’s capital city is sweltering through an unusual heat spike, with temperatures in Perth on Wednesday tipped to reach at least 34C.
That’s despite Tuesday’s top of 25C, Thursday’s forecast top of 29C, and a top of just 19C by next Tuesday.
Bureau of Meteorology forecaster Luke Huntington said Wednesday would feel more like summer in Perth because a trough that developed rapidly off the coast had brought hot northeasterly winds from inland northern parts of WA.
“The sudden fluctuation in temperature is a fairly common spring set-up for Perth,” Mr Huntington said.
“We typically see one or two warm consecutive days before the temperature drops back again.
“What is unusual is the intensity of the heat for this time of year, with 34C being early for this time of year.”
The record top temperature for a September day in Perth was 34.2C in 2014, so there’s a good chance that could be smashed by the late afternoon.
It came close to being beaten in September 2019 when 33.1C was recorded on one day.
“(Thursday) is cooler because the trough will have moved inland bringing a cooler southerly wind flow throughout the day,” Mr Huntington said.
“Perth will be in a cooler onshore flow with a cold front to move through later Sunday and into Monday. This will drop the temp back to 20C on Monday.”
With temperatures nearing 30C by late morning, locals and tourists alike could be seen lounging in CBD parks or sticking to the shade as they went about their business.
The bureau reported the temperature in Perth at 32.3C at 1.10pm AWST.
