But, according to a Bureau of Meteorology update at around 11am this morning, it was not as cold as the live data displayed throughout the day.
The Bureau puts yesterday top temperature at 6.6ºC - a whopping 1.1ºC higher than originally displayed.
That lowest maximum temperature is still a historical anomaly though, ranking it among the top 10 coldest days in Shepparton since 1962 - when including the data from the Lemnos weather station.
Wednesday was the coldest day in Shepparton since July 9, 1995, where a cold snap saw the mercury reach 6.1ºC (on July 8) and 6.4ºC on consecutive days.

The News understands Shepparton has shivered through its coldest day in decades, including the lowest maximum temperature ever recorded at the Shepparton Airport weather station.
While official confirmation will have to wait until the Bureau of Meteorology updates its daily data tomorrow, the hourly weather observations for Shepparton today, June 21, 2023, put the top temp at 5.5ºC just after 2pm.
This is significantly below the previous lowest maximum temperature at the Shepparton Airport gauge - which became operational in 1996 - of 6.7ºC on July 11 of that year.
Data from the Lemnos (Campells Soup) weather station, which extends back to 1962 from its closure in January 1996, marks July 3, 1984 as its lowest maximum temperature on record - a cool 4.8ºC.
The coldest June day on record, also marked at the Lemnos station, was 5ºC on June 28, 1966.
