Queensland's south-east can expect more stifling nights ahead as humidity packs "an extra punch" to above-average overnight temperatures, according to the Bureau of Meteorology (BOM).
A heatwave warning has been issued from today for much of the state's south-east, which will peak towards the end of the week.
Relief is not expected until Sunday, BOM meteorologist Shane Kennedy said.
Brisbane's minimum temperature overnight was just 25 degrees — compared to the city's overnight average of 21 — but felt like 28.
Daytime temperatures are also expected to be about four degrees above average for much of the south-east, pushing temperatures into the mid-30s.
Above-average temperatures will "only being made worse by humidity," Mr Kennedy said.
"Not only is it a heatwave just purely based on the temperature but high humidity has really been compounding that and packing an extra punch and unfortunately that’s likely to continue the next few days and getting even hotter on Friday and Saturday," he said.
A low-intensity heatwave has been forecast for much of the east coast, starting around Cairns and going all the way down to northern NSW and inland as far as Toowoomba, with warm and humid conditions expected over the next few days.
Conditions will change on Sunday, Mr Kennedy said.
"It looks like we’ll finally get some cooler air breaking that heatwave and it will be both cooler and drier finally. It's a long way to go but relief is in sight."
