You would be forgiven for thinking you'd woken up in the middle of a snow slope.
Sydney's coldest day of the year so far hit on Thursday morning.
Temperatures reached a low of 6.1 degrees, making it the chilliest start to the day in 2019.
Australia registered its lowest June temperature in eight years as frost formed in every state and territory.
Clear skies, light winds and a lingering mass of cool air combined to send the mercury plummeting across a large area of southern and central Australia during Wednesday night.
Although temperatures are not unusual for this time of year, the recent mild start to winter has also made it feel much colder.
The rest of the day will barely nudge 17 degrees.
Friday will see some sun, though it will still be cold, with a predicted top of 16 degrees. That temperature should remain much the same heading into the weekend, which could see some showers.
