- Most of the state's north had less than 20% of the monthly average rainfall for April.
- Mildura Airport did not record any rainfall this month.

- The Victorian minimum temperature was 0.65 °C below the April average, the lowest since 2008.
- Daytime temperatures were close to average across Victoria away from the north-west, due to the multiple bursts of cold southerly air and increased cloud cover, which followed the passage of cold fronts.

- Falls Creek and Mount Hotham had their highest April temperature on record on the 2nd.
- A polar air mass followed in a wake of a strong cold front that crossed Victoria on the 10th, bringing damaging winds, powerful surf along the coast, and daytime temperatures more than 8 degrees below the April average at many sites.
- Another strong cold front crossed Victoria on the 20th bringing more cold air, gusty south-westerly winds and showers for much of the state.
- The lowest night-time temperature recorded in Victoria in April was −4.9 °C at Mount Hotham on the 21st.

- Victoria's year-to-date mean temperature was around 0.2 °C below average, the coolest January–April period since 2004.
Strong winds and snow
- A strong cold front on the 10th brought a sharp decrease in temperatures to the state, and snow to the elevated parts of Victoria; Mount Baw Baw, Lake Mountain and Mount Buller recorded between 20 and 40 cm of snow. Lighter snowfalls were recorded at Falls Creek and Mt Hotham, with some graupel and light snow flurries observed to lower elevations at Marysville and the Dandenong Ranges.
- Damaging winds this April were associated with the passage of a cold front on the 10th, and the strongest wind gusts of 124 km were reported at Wilsons Promontory Lighthouse on the 10th and 11th.
- More snow fell on the Victorian Alps in the wake of a vigorous cold front that crossed Victoria on the 20th bringing low temperatures, rain and snow.

Notes
The Monthly climate summary, generally published on the first working day of each month, lists the main features of the weather in Victoria using the most timely and accurate information available on the date of publication; it will generally not be updated. More extensive discussion of significant weather events, along with later information and data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review.
This statement has been prepared based on information available at 9 pm on Sunday 2 May 2021. Some checks have been made on the data, but it is possible that results will change as new information becomes available.
In some situations, some or all of the rainfall is in the form of hail or snow. In these cases the totals given are for the water equivalent: the depth of liquid water that results from melting any frozen precipitation. There can be significant 'undercatch' of snow in strong winds, meaning the true precipitation can be higher than that reported.
Averages for individual sites are long-term means based on observations from
all available years of record, which vary widely from site to site.
They are not shown for sites with less than 10 years of record, as they cannot then be calculated reliably.
The median
is sometimes more representative than the
mean
of long-term average rain.
The Rank indicates how rainfall this time compares with the climate record for the site,
based on the
decile ranking
(very low rainfall is in decile 1, low in decile 2 or 3,
average in decile 4 to 7, high in decile 8 or 9
and very high is in decile 10).
The Fraction of average shows how much rain has fallen this time as a
percentage of the long-term mean.
Where temperature area averages are mentioned, they are derived from the ACORN-SAT dataset.
