Sydney's hottest January night on record

The mercury then climbed again, cracking 30 degrees at 2am.
A series of other weather stations - including those at Surry Hills, Penrith, Richmond, Horsley Park and Camden - broke records with minimum temperatures between 26 and 28 degrees.
Penrith broke the overnight low record by 4 degrees, according to Rebecca Kamitakahara of the Bureau of Meteorology, where it got down to 28.8 degrees at 6am. At midnight, it was still 35.6 degrees after Friday's maximum temperature of 44.1 degrees.Â
Weatherzone meteorologist Graeme Brittain described the Friday night temperature peaks as "quite exceptional."
For those looking to find solace at the beach, a "window of opportunity" is set to present itself between 3pm and 7pm on Saturday before possible showers, Mr Brittain said.
The western suburbs can expect showers between 10am and 2pm, while the chance of rain for the eastern suburbs is lower.
Penrith is forecast to reach 39 degrees while the inner city and eastern suburbs are due to reach the low 30s.
"It will be cooler tonight, but it will still be humid and uncomfortable," senior Weatherzone meteorologist Jacob Cronje.
The heat has been delivered by a low pressure trough moving from the north-west of the state.
Sunday is set to be the first of several milder days for the city before it heats up again on Tuesday.Â
Sunday is forecast to reach a top of 26 degrees, with the chance of showers, while Monday will be partly cloudy with a top of 29 degrees.Â
The heat is due to set back in on Tuesday, with a sunny top of 34 degrees, followed by 33 degrees, and showers, forecast on Wednesday.Â
In the west, there is only one day of reprieve from the heat at Penrith - Sunday, when the mercury is forecast to reach 28 degrees.Â
It will heat up again on Monday with a top of 34 degrees before Tuesday's scorcher of 40 degrees.Â
Meanwhile, the Rural Fire Service has declared "very high danger warnings" for nine out of 21 state districts in NSW.Â
