NSW is set to be engulfed by a second wave of extreme heat, but without the catastrophic fire conditions.
The Bureau of Meteorology (BoM) has forecast temperatures in the mid-40s in some parts of the state tomorrow, with even higher temperatures forecast for Saturday.
"Conditions are much better across the state on Thursday, but we are expecting it to warm up on Friday, and even more on Saturday," said BoM senior meteorologist Julie Evans.
Temperatures in Sydney's western suburbs are expected to reach the high 30s, possibly 40s, on Saturday.
"The good news is that the wind is not expected to be as strong as it was," Ms Evans told AAP today.
The forecasted wind conditions will come as a relief to firefighters who continue to battle blazes around the state.
The BoM also does not expect the heat to linger over Sydney as it did on Tuesday, where temperatures stayed around the 35C mark until 3am (AEDT) yesterday.
That day, Sydney recorded a peak temperature of 42.5C, just shy of the forecast 43C that would have made it the third hottest day on record.
Tomorrow's temperatures are expected to reach 33C in Sydney, followed by 35C on Saturday.
A cool change will also arrive on Saturday afternoon, although places in the north of the state, the upper Hunter and inland NSW will continue to be gripped by a heatwave, the BoM said.
