Hot-water-bottles were hot property over the weekend.
The cold June just got colder, with confirmation that the state has had its equal-coldest June night on record.
Bureau of Meteorology figures show the mercury plummeted to -6 degrees at Norseman Aerodrome in the early hours of Sunday, the same reading recorded at Collie in 2006.
It topped off a chilly three days at the recording station, with -4.7 degrees on Friday and -5.4 degrees on Saturday.
Norseman's aerodrome aside, other parts of the state also had a particularly chilly Sunday morning.
The town itself recorded -4.6 degrees, Southern Cross Airfield saw a temperature of 4.2 degrees, while at Hyden it got down to -3.5 degrees.
The sub-zero temperatures followed Perth's second-coldest night on record, with a minimum of -0.6 degrees on Saturday morning, 0.1 degrees above the 2006 low.
While temperatures are not forecast to drop to those levels in the next few days, clear skies and a lack of rain will keep them in the low single figures overnight.
