Melbourne has woken to its coldest morning of the year, with the temperature dropping to a chilly 2.4 degrees.
Bureau of Meteorology senior forecaster Christie Johnson said clear skies, light winds and dry air combined to make it the coldest day.
The last time it was colder was exactly this day a year ago when the mercury plummeted to 0.8 degrees.
Ms Johnson said Monday morning's recorded temperature is not unusual for this time of year.
"This is pretty normal as you tell by the fact the coldest day last year was in fact this day," she told AAP.
The second coldest day this year was on June 19 when the temperature fell to three degrees.
A mostly sunny day is forecast for Melbourne on Monday, with an expected top of 14 degrees.
Local fog and frost is expected, mainly around the outer suburbs, while light northerly winds will increase to 15 to 25 km/h around the middle of the day.
