According to the Bureau of Meteorology, Canberra hit a high of 31.1 degrees at 3pm on Wednesday making it the capital's hottest April day in 30 years.
Wednesday's hot, gusty day followed another unseasonably warm autumn day.
Tuesday was the warmest April day in more than a decade at 29.6degrees.
Last time April temperatures climbed that high, Canberra was in the throes of the millennium drought, where community ovals were baked bare and thousands of trees dried to death.
Weatherzone meteorologist Brett Dutschke said the remarkable heat spell was being felt right across Australia.
"We've had heat building over north-western Australia for the past week as a result of the monsoon becoming inactive in northern Australia and some of that heat has been flowing through central Australia," Mr Dutschke said.
"We've had record-breaking April hot days in WA Pilbara and Kimberley and significantly warm run over central Australia and some of that heat has drifted to south-eastern Australia on north-easterly winds ahead of a colder change." Thankfully, for Canberrans, Thursday will be a cool chaser to Tuesday and Wednesday's unusually warm weather.
The temperature will plunge 10 degrees to a predicted high of 21 degrees on Thursday and Friday before a slightly warmer 24 degrees on Saturday.
"The days and nights will cool down and we can expect mostly sunny days and clear cool nights although some mornings might start off a little cloudy," Mr Dutschke said.
Sydney on Wednesday posted its hottest April day on record, with the 34.2-degree reading beating a mark that had stood for 30 years. Suburbs from Camden in the south-west to Richmond in the north-west topped 36 degrees.
Australia has also just posted its hottest March in more than a century of reliable data after a scorching heatwave to start the month that the Bureau of Meteorology said in some areas approached "record levels for any time of the year".
NSW blew away records that had stood since 1940 and Victoria eclipsed the previous hottest March for mean temperatures, set in in 1974.
US climatologists are among the first to call March as being the hottest on record, globally, with a 0.63-degree departure from the norm for the 1981-2010 period.
Australia's famously variable climate means some long-standing records are hard to break.
Still, last month beat the record set in 1986 and seven of the warmest periods for each month have come since 2000.
"At the seasonal time scale, where natural climate variability gets smoothed out a bit, the warm extremes are more concentrated at the later end of the period," Blair Trewin, the bureau's senior climatologist, said.
"Winter, in 1996, is the earliest, with the others all occurring in the last 12 years – autumn 2005, summer 2012-13, and spring 2014," he said.
