Victoria in June 2021: above average rainfall; warm nights

June rainfall was above average in much of southern and eastern Victoria. Daytime temperatures were above average across most of the state's west and south, and very much above average in southern parts of the Central and Western districts. Night-time temperatures were above average across most of Victoria, the eight highest on record for the state as a whole and the highest since 2014.

Wettest June since 2014

  • June rainfall was above average in much of southern and eastern Victoria.
  • Averaged across the state, rainfall was 45% above the long-term June mean of 58 mm, making it Victoria's overall wettest June since 2014.
  • A low pressure system moved north from Bass Strait over Victoria on the 8th bringing heavy rainfall mostly to the south-west of the state.
  • Another complex low pressure system affected Victoria's east between the 9th and 11th, bringing with it destructive winds and heavy rainfall.
  • Rainfall totals at many sites in South and West Gippsland over the 3-day period ending at 9am on the 12th ranged between 100-300 mm.
  • Many sites had their highest June daily rainfall on record to 9am on the 9th and 10th, including Toorourrong, Cobden, Terang and Jindivick, all of which have more than 100 years of measurements.
  • This was the most significant rain event in west and south Gippsland since at least the June 2007 event.
  • Mount Baw Baw received 280.6 mm for the 24 hours to 9am on 10 June; this was the fifth–highest daily rainfall total on record for Victoria for any month and the third-highest for June.
  • Balook's total of 215.4 mm was the tenth-highest daily rainfall total for Victoria in June.
  • A cold front and a low pressure system brought more rainfall to Victoria on the 23rd and 24th, mostly to the north-east of the state.
  • With 398.2 mm, Mount Baw Baw was the wettest place in Victoria during the month.
  • Some sites had their highest total June rainfall on record or their highest total June rainfall for at least two decades.
  • Over the first half of the year, Victoria's rainfall was 7% above average.

Warmest June nights since 2014

  • Night-time temperatures were above average across most of Victoria, with large parts of the state's west and most of East Gippsland experiencing very much warmer than average nights.
  • The Victorian minimum temperature was 1.65 °C above the June average, the eight highest on record for June and the highest since 2014.
  • Ararat and Swan Hill had their highest June mean daily minimum temperature on record, while Mildura Airport, Ouyen, Kerang and Walpeup had their highest June mean daily minimum temperature for at least two decades.
  • High pressure systems brought clear skies and some very low daily minimum temperatures on the 5th and 6th, between the 20th and 22nd, and on the 29th.
  • The lowest daily minimum temperature in Victoria during June, −5.8 °C, was recorded at Mount Hotham on the 5th.
  • Daytime temperatures were above average across most of the state's west and south, and very much above average in southern parts of the Central and Western districts.
  • Victoria's mean maximum temperature was 0.54 °C above the long-term June average.
  • The year-to-date (January to June) mean maximum temperature was close to average, while the mean minimum temperature was just 0.20 °C above average, the lowest since 2006.

Damaging winds, floods and frost

  • Many sites in south-east Victoria received more than 100 mm of rain in the 24 hours to 9am on the 10th, leading to flooding in low-lying areas.
  • The Traralgon Creek caused major flooding on the 10th in Traralgon, with evacuation orders issued for parts of the town. Moderate to major flood warnings were also issued on the 10th and 11th for the Latrobe River at Thoms Bridge, the Tanjil River at Tanjil Junction, along the Thomson River near Sale, along parts of the Macalister and Morwell Rivers and for the Yarra River at Yarra Glen.
  • More than 200.000 homes and businesses in Victoria were left without power as the strong sustained winds, with gusts exceeding 100 km/h brought down trees and powerlines.
  • Many roads were closed due to flooding and due to downed trees and power lines. Victorian State Emergency Services responded to more than 9000 requests for help, mostly for fallen trees, building damage and floods.
  • Many parts of Victoria experienced large areas of frost on the 5th, 21st, 22nd and 29th, as night-time temperatures plummeted due to clear skies and light winds under strong high pressure systems.

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 am on Thursday 1 July 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.
