Melbourne has an average annual rainfall of around 537 mm, which is considered to be moderate compared to other cities in Australia. For example, it’s wetter than Adelaide and Hobart but drier than Brisbane and Sydney.

However, the city’s rainfall can vary greatly from year to year, with extreme variations in both wet and dry conditions.

1978 is the year with the highest recorded rainfall for Melbourne in the data analyzed. In that year, the city received a total of 820.8 mm of rainfall, which is significantly higher than the annual average.

This was followed immediately by the 1979-1983 Eastern Australian drought, which caused severe water shortages and agricultural losses across the region.

On the other end of the spectrum, 1997 had the lowest total rainfall for Melbourne, with only 310.2 mm of rainfall recorded. This marked the start of the 2000s drought in Australia, also known as the Millennium drought, which is considered to be one of the worst droughts recorded since European settlement.
