It didn't quite drop below zero on Easter Sunday, but it certainly felt like it as Canberra had its coldest morning in almost six months.
Friday's forecast for Sunday morning had been a brisk 3 degrees (before warming up to 17). Cold enough perhaps to have some Canberrans pondering breaking the "Anzac Day rule" for heating.
But the recorded temperature dropped even further, all the way down to 0.6 degrees at 6.32am.
That's the lowest reading at the Bureau of Meteorology's Canberra Airport station since October, when we last dipped below zero at -0.2 degrees.
And Sunday's apparent temperature dropped to -2.1 degrees, about 4.30am.
According to the Bureau of Meteorology, apparent temperature takes into account wind chill making conditions feel far frostier than their instruments can read, particularly in Alpine areas.
The bureau measures temperatures across the country using thermometers sheltered from the sun and wind.
An equation then estimates what that temperature feels like relative to wind speed and humidity.
It's a mathematical model designed to measure the comfort of an "appropriately dressed" adult walking outside in the shade - based off how people gain or lose heat.
The rest of Sunday is expected to be a sunny day with a top of 17 degrees, with some patchy light frost in the morning. Winds are expected to be light.
Monday is tipped to have some more early patchy fog, with a low of 2 degrees and a top of 19. The reset of the week is expected to reach tops in the low 20s.
One of established Canberrans' greatest joys at this time of the year is to tell horrified newcomers of the "Anzac Day rule" for heating.
To use a heater, fire or electric blanket before April 25 is a sign of weakness, the rule decreed, as the public holiday marks the true start of the wintry weather that will only ease up in mid-spring.
The Bureau of Meteorology has previously said that although cold snaps earlier in the year were possible, they became more frequent from the end of April and beginning of May.
Cold fronts restricted to Victoria and Tasmania during summer moved northward during that time, buoyed by air pushed from the Antarctic toward the top of Australia.
"There isn't an exact date, but generally by the end of April you have transitioning patterns from the virtual summer conditions to winter weather," a spokesman said.
