The first Friday of summer has given New South Wales a taste of what could be Australia's hottest summer on record.

About 40 bush and grass fires have been burning across the state, with an emergency level warning issued for an out-of-control blaze at Beni, near Dubbo, which has closed the Golden Highway in both directions.

An emergency level warning has also been issued for a fire burning at Bulahdelah on the state's Mid North Coast.

The Rural Fire Service's Ben Shepherd said a number of isolated rural properties were under threat from the Beni blaze, with anyone in the area advised to shelter in place.

Further along the east coast, the Bulahdelah fire has shut the Pacific Highway, with Mr Shepherd saying firefighters were battling strong winds and "trying conditions".

"We're seeing some unbelievable fire conditions on that fireground at the moment that is resulting in properties coming under threat," he said.

"We've seen a couple of grassfires and crop fires that have sprung up that [have] taken that attention of aircraft and crews, so it is proving to be a bit of a problematic afternoon.

"We are expecting conditions to deteriorate into tomorrow."

Heatwave warning

Authorities have issued severe to extreme heatwave warnings for large parts of the state, with people urged to take note of any signs of heat stress.

Sydney's temperature had climbed to 37.8 degrees Celsius by 1pm on Friday, exceeding the Bureau of Meteorology's (BOM) forecast of 35C and making it the city's hottest day since January 2024.

A sea-breeze has now reached the Observatory Hill station, meaning that could be the eventual maximum temperature for today.

Parts of Western Sydney bore the brunt of the heat, with paddleboarders Zoe and Briana among those cooling off at Parramatta Lake on Friday.

"It's always a trek to get out to the beaches," Brianna noted, saying those from inland suburbs were fans of the Parramatta swimming spot or any local pools.

Workers in Gregory Hill in Sydney’s south-west covered up from the elements, with the temperature forecast to hit 39C.

Meanwhile, at Cronulla Beach, Mary-Anne Kent said she enjoyed keeping active whatever the weather.

"I’m a bit of a lizard so it doesn’t really worry me," she said.

"I’ve gotten up, and I’ve done yoga, and I’m just about to go for an hour walk, then I’ll probably go for a swim.

"I don’t sit inside with the air conditioning, I'd rather be outside and living life."

Tom Avery, too, said he was not bothered by the heat.

“I love it, I’ve always loved it," he said.

“I’m very comfortable in it."

How hot will it get?

Across the state, Bellambi, in the Illawarra region,recorded its hottest December day in two years, reaching 36.7C by 1pm.

Albion Park's 37.9C was 12 degrees above the December average, and the area's hottest day since January.

BOM senior meteorologist Sarah Scully said the hot weather would be at its peak on Saturday, before a cooler change on Sunday.

"It's also going to be very, very windy [on Saturday] so we will have a fire weather warning current for much of eastern and inland and northern parts of New South Wales," she told ABC News.

"There's also a risk of a thunderstorm but not a lot of rainfall is expected with any storms that do form, which does create a concern with regards to dry lightning."

Sun safety

NSW Ambulance associate director of emergency management Steve Vaughan said even the fit and healthy could be struck down by the effects of the heat.

"Heatwaves have a cumulative effect over several days, which can have an impact on your health," he told ABC News 24.

"There's some parts of our community which are more susceptible to heat than others, those being the elderly, pregnant women, young children and babies, those who are socially isolated, the homeless."

A reprieve from the heat is expected on Sunday, with inland temperatures expected to drop to the mid to high 20s.
