Originally, the Bureau of Meteorology was predicting Saturday could get to a low of seven degrees.
If that occurred, it would be the first time Sydney has hit seven degrees in May since 1999.
“This is chilly for this time of year, and colder than we would usually get in May,” Hines said.
“And it’s not like we rebound back to warmer temperatures after [this cold spell]. The overnight minimum temperatures now for the next week look like they will stay in the high digits.”
Winds between 15 and 30km/h are also being forecast until Monday, bringing chilly air into the city from the coast.
Swadlings Timber and Hardware manager Ante Tasovac said people were coming in for firewood earlier than usual because of the cold weather.
“In the last month it picked up, it doesn’t normally happen till around June, July, but it’s got cold a lot quicker,” he said.
“We get lots of inquiries about it over the phone and we do sell a lot more than we used to.”

Customers were also using firewood as a cheaper alternative to electricity which Tasovac has noticed become more common as the cost of living hits more people.
“They do save a lot of money instead of just putting the air con or heater on all day,” Tasovac said.
On Friday, Sydney is set to experience a minimum of nine degrees and a maximum of 19.
On Saturday, things get even colder with a minimum of eight degrees and a maximum of 19.
