Victoria in June 2017: driest on record

Rainfall in Victoria during June was very much below average across almost all of the State, with large areas where rainfall totals were lowest on record. Daytime temperatures were above the long-term average across most of Victoria, while night-time temperatures were below average except in parts of the east and south of the State.

Driest on record June in Victoria

• With 13.7 mm averaged across Victoria, June rainfall was lowest on record since measurements began in 1900; it was 77% below the long-term mean of 59.4 mm
• Large areas in the north, west and central Victoria received less than 20% of average rainfall for the month
• A low pressure trough brought moderate falls to eastern and south-central parts of the State on the 6th and to the eastern Victoria on the 7th, with daily totals generally between 5 and 15 mm; higher daily totals were recorded only at several sites in the far east of the State
• A cold front which crossed the State on the 29th brought more rainfall to southern parts of Victoria
• The highest daily rainfall total in the State, 43.6 mm was recorded at Cann River on the 6th and Genoa on the 7th
• The wettest place in the State was Point Hicks with 84.0 mm during the month
• Many sites had their lowest total June rainfall on record and lowest total June rainfall for at least 20 years

Mild days and cold nights

• Victoria's mean maximum temperature was 0.51 °C above the long-term June average
• In contrast, minimum temperatures were below average across most of the State, although eastern and southern parts were close to average
• For Victoria as a whole the mean minimum temperature was 1.27 °C below average, the coldest since 2006
• Several sites had their lowest June mean daily minimum temperature on record
• Many places in the central-north Victoria (including Echuca Aerodrome, Kyabram, Tatura, Shepparton Airport, Mangalore Airport, Redesdale, Wangaratta Aero and Rutherglen) had a record 30 consecutive days during June with minimum temperature 5 °C or below
• Mt Hotham recorded both the coldest day during the month, -1.9 °C on the 6th, and the coldest night, -6.6 °C on the 30th

High pressure systems dominate

• Mean sea level pressure was more than 5 hPa above average for June across much of southern Australia
• The dominant high pressure systems reduced the number of rain-bearing low pressure systems and cold fronts affecting southern Australia
• Many sites that measure air pressure across Victoria each day, reported their highest monthly 9am mean sea level pressures on record for June
• Average wind speeds were much lower than the long-term June average at many sites across Victoria
