Spring has arrived with a fiery intensity, as October temperature records are being shattered across the nation.

According to Weatherzone, several states experienced unprecedented heat for October yesterday. Official confirmation is pending, as maximum temperatures are assessed over a 24-hour period from 9am to 9am.

The weather service reported that Birdsville in Queensland reached a sweltering 44.9 degrees, narrowly missing the state’s October record by just 0.2 degrees.

Elsewhere in Queensland, regional highs were noted, with Ballera hitting 44.2 degrees and Thargomindah reaching 43.1 degrees.

However, the extreme heat wasn’t confined to Queensland alone.

In South Australia, Moomba Airport reached 44.1 degrees, breaking the previous record of 43.5 degrees.

And Oodnadatta registered 44 degrees just after 3.30 pm, Weatherzone said – though that was shy of South Australia’s overall October record high of 45.4 degrees.

Regional New South Wales also copped it, with Tibooburra in the far north-west breaking records to reach 42.6 degrees.

White Cliffs, in the same region, hit 42.3 degrees.

“The pool of unseasonably warm air in Australia’s interior will begin to dissipate in South Australia on Tuesday, however the (south-west) corner of Queensland and the (north-west) corner of New South Wales can expect another scorcher on Tuesday,” Weatherzone said.

“Tuesday’s temperatures at some locations could even potentially exceed Monday’s, which obviously means that more records could tumble.”

Temperatures in Sydney today are expected to reach a mild 23 – but will soar tomorrow with a forecast maximum of 38 degrees, according to the Bureau of Meteorology.

Brisbane will reach 30 degrees today and tomorrow before rising to 35 on Thursday.

Adelaide, meanwhile, is going in the other direction, with temperatures plummeting to below 20 after today and storms and rain forecast.
