A late-season frost and very cold mornings hit parts of South Australia starting around October 27, 2019. Some areas saw their lowest back-to-back minimums in more than 100 years late in the year.
A high-pressure system in the cold front enabled clear skies and light winds to combine with a mass of cold air during the past two nights, giving ideal conditions for low minimum temperatures.
This type of weather pattern is not rare during spring in the state, which is between September to November, however, several areas were remarkably cold for this late in October.
The morning on Monday, October 28, was the coldest this late in the year for more than 25 years in Kingscote, 15 years at Robe, and 14 years at Stenhouse Bay.
Rutherglen town in Victoria dropped to -2.1 °C (28.2 °F) on Sunday morning, October 26, and -0.9 °C (33.6 °F) early on the following day.
These temperature records were well below the October average minimum of 6 °C (42.8 °F).
Those days were also the first pair to hit below 0 °C (32 °F) this late in the year in records since 1913.
Temperature is expected to get less cold in the next days as warmer air returns.
