Melbourne has shivered through its coldest morning in nine months but May will still go down as another warmer-than-average month.
Clear skies and light winds took temperatures in the city on Tuesday down to 3.6C just before 7am.
It was the coldest morning in the CBD since August 4 last year.
At Laverton, Melbourne Airport and Viewbank the temperature was at, or below, 1C, while Coldstream experienced the lowest Melbourne temperature with -2.3C recorded just before sunrise.
Elsewhere in the state, Shepparton dipped to 0C but most of Gippsland, the Mallee and Wimmera enjoyed more comfortable nights.
The chilly morning was not nearly enough to cancel out a very warm first fortnight of May, however, when minimum temperatures were around 5-7C above average.
Statistics are yet to be finalised but both maximum and minimum temperatures for the whole month have been well above average, says Bureau of Meteorology senior forecaster Rod Dickson.
"But it has really cooled off in the last week with temperatures around the mid-teens which is probably what you'd more expect for the end of May," he told AAP on Tuesday.
Rainfall has also been above average for most of Victoria.
May's been the wettest month in Melbourne since July 2015 with 57mm of rainfall.
Echuca and Wodonga recorded twice their May averages.
East Gippsland missed out though with just 60 to 80 per cent of their normal rainfall.
"The main driver of that (wet month) has been the breakdown of El Nino in the Pacific," Mr Dickson said.
"Quite often when that breaks down in late autumn we get some quite decent rainfall."
Looking ahead, temperatures in Melbourne are expected to stay stable into the first week of winter, with overnight lows of 6C and highs of 16C.
The only rain forecast is a few showers over the weekend.
While the wet in the state's northeast should continue, Mr Dickson says southern Victoria has a 50-50 chance of below-average rainfall in June.
