Despite wild weather towards the end of the month, the Wimmera experienced a drier September than average.
Rainfall was below average across the Wimmera.
Bureau of Meteorology measurements showed Horsham received 31.6 millimetres of rain throughout the month.
This is compared with an average of 47.7mm for the month during the past decade.
Ararat received 49.7mm of rain in September but fell below average compared with the past 10 years.
The city has measured an average of 59.3mm of rain in September since 2001.
Nhill had 27.2mm but was well below its September average of 42.9mm.
Similarly, Warracknabeal received 24.7mm compared with the long-term average of 42.6mm.
Cooler weather towards the end of September also caused snow on Mt William in the Grampians.
Horsham man Bob Wynne headed to the mountain on Saturday, armed with his camera.
He said he often headed to the mountain whenever snow was forecast there.
Mr Wynne said it had snowed along the Halls Gap-Dunkeld Road and trees and bushes were well-covered and icy, along with nearby peaks.
He said there was also plenty of snow on the summit.
"It had been quite sunny while at the top but as we descended to the carpark, dark clouds could be seen to the south and around 11.30am snow began to fall again,'' he said.
Mr Wynne said the snowfall started lightly but soon became quite heavy.
"Up top, out of the shelter of trees, it would have been quite blizzard-like, not so good for those hikers poorly attired for the weather,'' he said.
"But the hordes of children then arriving had a ball as you can imagine, with much tossing of snowballs and general hilarity, not restricted to children of course.''
Paul Yole also headed to the mountain with his camera and took photos between 7.30am and 8am on Saturday. He said the temperature at the time was about -3 degrees Celsius with light snow falling.
