Some of the most significant and widespread minima were experienced about South Australia’s Mid North,
Flinders and North East Pastoral districts. Located 365 km north of Adelaide, Hawker felt its chilliest August morning in 35 years worth of records. The mercury fell to just minus five overnight, a huge nine degrees below average.
Clare also shivered through a cool night with temperatures dropping seven degrees below average to a minimum of minus two. This made it the coolest August night since 1994. Yunta was one of the coolest locations state wide with a low of minus five, more than nine degrees below the August average.
The story continued closer to the coast where Minalton, despite not being as cool as inland regions felt their coolest night for any month since 2008 at 0.7 degrees.”
