A “strangely warm southerly” continues to sweep across Sydney on Friday, causing hot and windy weather.
And there will be little relief at beaches in New South Wales and Queensland as Cyclone Winston heads west, creating increasingly large swells on Friday turning into large, dangerous and powerful surf over the weekend.
Following Thursday’s high of 33 degrees, Friday’s weather will be very breezy with temperatures reaching 29 degrees, said Rob Sharpe, a meteorologist with Weatherzone.
The cool change expected on Thursday night was warmer than expected, he said.
Usually a cool change will cause temperatures to drop to below 20 degrees, Mr Sharpe said, but on Thursday night the temperature actually jumped a degree when the change hit Sydney about 2.30am. At 6.30am, it was still 23 degrees.
“It is rare for this to occur where the temperature stays up for this long,” Mr Sharpe said.

Another abnormality was the rise in temperature after the sun went down on Thursday. Usually the mercury goes down with the sun, but at Sydney Airport on Thursday night, temperatures rose after the 7.36 pm sunset from 30.6 degrees to 31.2 degrees over the following two hours.
The Bureau of Meteorology is also warning that large and powerful surf conditions will make rock fishing, swimming and surfing increasingly dangerous this weekend.
Mr Sharpe said Cyclone Winston was moving west to Queensland’s coast. A category five tropical cyclone when it hit Fiji, wreaking disaster and taking lives, it has now turned into a extra-tropical cyclone. A tropical cyclone gets energy from warm air and waters, but extra-tropical cyclones get their energy from a mix of warm and cooler patches of air.
