COLAC residents have sweltered through the hottest day since Black Saturday.
Bureau of Meteorology duty forecaster Michael Efron said the Mount Gellibrand weather station north-east of Colac, recorded 40.8 degrees Celsius around 4.00 pm Monday.
“Colac would have been a bit hotter than Mount Gellibrand,” he said.
It was the hottest Colac day since February 7, 2009, when it reached 45.4 degrees.
The temperature dropped back to under 30 degrees by 9.00 pm Monday, and stayed around 18 degrees for much of the evening.
Monday’s maximum temperature at Cape Otway was 37.6 degrees, at 12.30pm.
“The hottest part of the state was actually the south-west,” Mr Efron said.
“We saw maximums in the low 40s across the area.”
Mr Efron said a change would arrive this morning, causing temperatures to drop.
“We’ll see a strong south-westerly change that’ll bring temperatures right down to the low 20s,” he said.
Today’s forecast top is 23 degrees, Thursday 22 degrees and Friday 24 degrees.
Mr Efron said the weather would be “warming up a bit for the weekend”.
