An overnight drenching has dumped almost 20mm of rain on Ballarat, delivering the city’s wettest day since May.

Heavy falls hit just before dinnertime on Wednesday night, with SES crews beginning to receive calls for assistance about 6pm.

Duty officer Josh Smolenaers said more than 10 homes suffered minor flooding across Ballarat in a one-hour period from 7.30pm.

"We had about 13 jobs for the night until about 11pm, most for flooding and building damage," he said.

"We try to protect furniture and, if ceilings have been damaged, make sure structures are secure."

One house at Bakery Hill ended up with a flooded room when water got into the lining of the walls. 

But farmers and gardeners were counting their blessings as the soaking came off the back of five driver-than-average months in a row for the city.

Wednesday was Ballarat’s wettest day since May 28, when 20.6mm of rain fell.

The gauge at the airport registered 17.4mm of rain by Thursday morning, with the heaviest falls between 7pm and 11pm on Wednesday night.

The wet weather created hazardous conditions on Ballarat’s roads, with police responding to several crashes on Wednesday night.

But any serious injuries were avoided.

The Bureau of Meteorology has predicted the wintry blast will clear up in time for the weekend.

Saturday is heading for 19 degrees and the mercury is tipped to climb to a balmy 22 degrees on Sunday.
