Fairfield recorded its second hottest day in 20 years on Saturday as temperatures soared to 44.5 degrees.
It was just shy of the hottest day since 1997, set back on January 18 in 2013 which reached 44.9 degrees, according to the Bureau of Meteorology.
It formed part of a two-day heatwave with Friday’s temperature reaching 43.8 degrees. To put it in to perspective, last year’s two day temperature total for the same two days was 59.5 degrees – almost 29 degrees cooler than Friday and Saturday.
Before Friday, NSW had never had a February day above 42 degrees, based on averaged maximums in the state.
The state cleared that mark with 42.4 degrees on Friday and Saturday's average temperature leapt even higher, touching 44.02 degrees.
Remarkably the temperature on Saturday didn’t peak until 6.30pm after reaching 30 degrees at 10.30am.
At 11.30pm it was still a balmy 25 degrees.
