Australia in June 2019

In brief

  • Warmer than average June for Australia
  • Mean maximum temperature above average for large parts of the west and southeast of the country
  • Mean minimum temperature below average for areas scattered across the mainland, including much of South Australia
  • Rainfall for the month below to very much below average for very large areas, including most of New South Wales, eastern Western Australia, and western South Australia
  • Rainfall above average for parts of western Western Australia, inland northern Queensland, and pockets of western Victoria
  • It has been the second-warmest January–June on record for Australia (spanning 110 years), with rainfall also below to very much below average over most of the country, and seventh-lowest for Australia as a whole

Temperatures

June was warmer than average for Australia as a whole, with the national mean temperature 0.26 °C above average. The mean maximum temperature for the month was 0.54 °C above average, while the mean minimum temperature was close to average (0.02 °C below average).

While June overall was relatively close to the long-term average, for the year to date, Australia has observed the second-warmest mean temperature on record for the January–June period. The mean maximum and mean minimum temperature have respectively been the highest and third-highest on record for Australia over the same period.

Maximum temperatures were above to very much above average over much of Western Australia, and adjacent areas of South Australia and the far southwest of the Northern Territory. However, the mean maximum temperature for the month was close to average for the coastal northwest of Western Australia, and much of northern South West Land Division, southern coast, and the inland areas between. June days were also warmer than average for Tasmania, Victoria, New South Wales except the far northwest, and greater southeastern Queensland. Cooler than average mean maximum temperature was only observed in a few scattered pockets in central to northern Queensland and the north of the Northern Territory.

The mean minimum temperature for the month was cooler than average in large areas scattered across Australia, including on the northern coast of Western Australia, the south coast of Western Australia near Cocklebiddy, much of pastoral South Australia and the eastern agricultural districts, parts of the coastal Top End and southern Northern Territory, pockets of central western and inland Queensland, parts of southern New South Wales and far northwestern Victoria, and the northeastern tip of Tasmania.

On average, nights were warmer than average for most of coastal eastern Australia between about Nowra in New South Wales and Gladstone in Queensland, most of southwestern Victoria, west coast and southern Tasmania, an area of Western Australia's southern Interior and northern Kimberley and adjacent northwestern Northern Territory, and about the Gulf coast and parts of the Peninsula coast in Queensland.

The first days of June were warm for the west of Western Australia, with a number of sites in the southwest setting new June temperature records for high daily maximum temperature.

A cold front early in the month led to cool temperatures across much of eastern Australia, including snow at some locations (see rainfall section).

Clear skies associated with a high pressure ridge between the 11th and 13th brought a warm period for New South Wales, including record-warm days for June at a number of sites.

High pressure later in the month brought a cool period to southeastern Australia between the 20th and 27th, with some records set at short-term sites in inland southern Queensland on the 22nd, in South Australia between the 22nd and the 24th, and in New South Wales, and Victoria between the 21st and 23rd. Cool nights also affected Tasmania and the ACT, but with fewer extremes.

Rainfall

Nationally, June rainfall was below average, with Australia ranking 25th-driest out of 120 Junes. Rainfall was below to very much below average across most of New South Wales, extending into much of southern Queensland, and adjacent border regions of South Australia and Victoria. For the Murray-Darling Basin as a whole, June rainfall was the tenth-lowest on record. For the year to date (January–June), rainfall has been below to very much below average over much of Australia.

Rainfall for the month was also below average for southern Tasmania, the western half of South Australia, much of eastern Western Australia, and large parts of the Northern Territory. It should be noted that average June rainfall is low for much of the Northern Territory and the Kimberley in Western Australia.

Rainfall for June was above average for a large area in the west of Western Australia, spanning the northern to central South West Land Division, western Gascoyne, and parts of the southern Goldfields District. Rainfall was also above average for the month in inland northern Queensland, and in parts of southwest and central west Victoria, and the western half of the Central District in Victoria.

In the east, a complex low pressure system and cold front produced a cold southerly burst between the 3rd and the 5th, resulting in snowfall reaching southern parts of Queensland's Darling Downs, sufficient falls in New South Wales' Blue Mountains to necessitate road closures, and heavy falls in the alpine region. At lower elevations, heavy rainfall led to some daily records for June in Victoria.

A strong cold front and associated cloud band brought heavy rainfall to South Australia on the 12th, with some sites observing their wettest June day, including two sites with observations spanning more than 100 years.

A strong cold front and associated cloud band produced locally heavy falls across Western Australia's South West Land Division between the 23rd and the 24th, leading to daily rainfall records for June at a few sites. For the month as a whole, numerous sites had their wettest June on record or wettest June for at least 20 years.

Towards the end of the month, moderate to locally heavy falls were reported over much of the southeastern mainland and northern Tasmania, associated with a low pressure system east of Tasmania and a cold front passing over the southeast. This system also produced strong and damaging winds, with gusts in excess of 100 km/h over exposed and elevated areas, and a line of gusty thunderstorms on the 29th which produced suspected tornados at Tocumwal in the New South Wales Riverina, and at Axe Creek near Bendigo in Victoria.

Notes

The Monthly Climate Summary is prepared to list the main features of the weather in Australia using the most timely and accurate information available on the date of publication; it will generally not be updated. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review, usually published in the fourth week of the following month.

Climate Summaries are usually published on the first working day of each month.

This statement has been prepared based on information available at 1 pm EST on Monday 1 July 2019. Some checks have been made on the data, but it is possible that results will change as new information becomes available, especially for rainfall where much more data becomes available as returns are received from volunteers.

Long-term averages in this statement and associated tables are for the period 1961 to 1990 unless otherwise specified. Temperature area averages are derived from the ACORN-SAT version 2 dataset. Rainfall area averages, along with rainfall and temperature maps, are derived from the AWAP dataset.
