Queensland’s capital is set to swelter under its hottest October day in years.

In Brisbane today, temperatures are expected to climb to 35 degrees, which is over 9 degrees higher than the average for this time of year.

Brisbane will be Australia’s warmest capital city, while areas including Ipswich, Gympie and Logan will reach the mid-30s.

Rockhampton is expected to push 39 degrees.

If today’s temperature reaches 35 degrees, it will be the warmest October day for Brisbane since 2021.

Tomorrow and Saturday are forecast to be a little cooler, but temperatures will still in the high 20s.

Sydney is also facing a scorching start to October after its second-hottest September ever.

The weather reporting site also said the month as a whole was the second-warmest September siince 1858, when weather records began.

According to Weatherzone, Sydney is experiencing an average maximum daily temperature of 23.5 degrees this month, which is 3.3 degrees above the long-term norm. The daily minimum temperature stands at 13.1 degrees, about 1.9 degrees higher than the usual average.

“The only time September was warmer in Sydney than 2025 was in 2013 for both high and low temperatures, with 2023 slightly surpassing this year in maximum temperatures,” reported Weatherzone.

Temperatures in early October are set to continue the trend, with the mercury rising to 30 degrees on Sunday for the NRL and NRLW grand finals.

The women’s grand final, which will be played before the men’s, will take place mid-afternoon, during likely oppressive heat.

Temperatures will drop early next week from that high, but will remain in the mid to high 20s, according to Bureau of Meteorology forecasts.

Weatherzone attributed the heat in recent weeks to both the overall warming climate and a sudden stratospheric warming over Antarctica.

“The SSW is a weakening of the polar vortex which in turn leads to a negative Southern Annual Mode (SAM),” Weatherzone said.

“This tends to produce more frequent spells of warm, windy conditions on the NSW coast.”
