In May 1982 rain forced punters home early from the Warrnambool racecourse.
Many called it a day following heavy downpours after race five, depleting the crowd of about 6000.
The track was changed from slow to heavy about 3pm and race six, the Kevin Lafferty handicap, was run before the next downpour.
Bookmakers said betting was affected by the rain, and before race seven, the Rosebowl, punters were wary of venturing out into a now muddy betting ring.
By the last race the course was beginning to look deserted, and only 1000 people were there to see the sun break through.
While 29mm of rain fell, the on-course figures increased by about $100,000 over the second day last year to total $271,935.
