Australia in June 2014

In Brief

Maximum temperatures during June were warmer than average across much of the eastern States and around the coast of the western mainland, and very much warmer than average for Tasmania, central southern Victoria and parts of the east coast. Minimum temperatures were also warmer than average for much of eastern Australia and very much warmer than average for the southeast, while a large area of Western Australia and smaller parts of central Australia recorded below-average June minimum temperatures. For Victoria and Tasmania mean temperatures were the seventh- and tenth-warmest on record for June respectively. The national maximum temperature anomaly of +0.54 °C and minimum temperature anomaly of +0.38 °C combined to give a mean temperature anomaly of +0.46 °C.

June rainfall was below average for the western half of Australia, parts of Tasmania and areas of coastal northern New South Wales and southeast Queensland. Rainfall was above average around the Gulf of Carpentaria and Cape York Peninsula as well as coastal South Australia, much of Victoria and parts of southeastern and central New South Wales. For Australia as a whole, rainfall was 32% below average for June.


Temperatures

June was generally a warm month for eastern Australia, with both maximum and minimum temperatures for the month above average. Maximum temperatures were warmer than average for the southern half of Queensland, most of New South Wales excluding central regions, Victoria and Tasmania as well as for the Top End, large areas around the coast of Western Australia and an area of northeastern South Australia. Maximum temperatures were in the highest 10% of June records for Tasmania, central southern Victoria and along the east coast between central New South Wales and greater southeastern Queensland. For Tasmania it was the eighth-warmest June on record in terms of maximum temperatures. The national area-averaged maximum temperature anomaly was +0.54 °C.

Minimum temperatures were above average for the majority of eastern Australia, extending into the Roper–McArthur District of the Northern Territory and much of southern South Australia. Minima were in the warmest 10% of June records for southeast South Australia, nearly all of Victoria, parts of southern New South Wales and smaller areas of northern and southern Tasmania and parts of coastal Queensland. For Victoria the June minimum temperature anomaly, +1.86 °C, was the fifth-warmest on record. In central and Western Australia a lack of rainfall and associated cloud cover resulted in large areas of below-average minimum temperatures, mostly in the west of the Alice Springs District and between the north of the South West Land Division and Interior District of Western Australia. Averaged nationally, mean temperatures were slightly above average at +0.38 °C.

While the national area-averaged mean temperature anomaly for June was relatively modest at +0.46 °C, mean temperatures for the first half of the year (January–June) were the highest on record for Queensland, New South Wales and Victoria, second-highest for South Australia and fourth-highest for Tasmania and Australia nationally. The twelve-month mean temperature for the July–June (financial year) period was a solid highest-on-record for Australia, Queensland, New South Wales and South Australia. The national anomaly of +1.08 °C was 0.18 °C above the previous record (held by the period ending June 2010). The July–June year anomaly can be interesting as it provides a way of examining conditions across the warm season as a whole, which can capture the influence of signals such as El Niño and La Niña.

Rainfall

Nationally-averaged rainfall during June was 32% below the long-term mean. Most of Western Australia, the southwest of the Northern Territory and northern South Australia recorded below-average monthly totals, as did smaller areas in along and north of the Murray River around Mildura, in southern Tasmania and along the east coast between Newcastle and Rockhampton. The Northern Territory recorded the largest departure from mean rainfall at 77% below average and Western Australia followed closely at 72% below average for that State's seventh-driest June on record, although the Northern Territory and north of Western Australia are typically dry at this time of year.

Rainfall was above average for far northern Queensland extending across the Cape York Peninsula and around the Gulf of Carpentaria into the eastern Top End, in a small area of Queensland's Lower Western District, in central New South Wales west of the Great Dividing Range and from southeastern New South Wales, through much of Victoria and along the coast of South Australia to about Ceduna. In Queensland, rain was mostly the result of persistent onshore flow across the northern tropics, while weak upper level troughs brought rainbands through parts of the tropics mid-month. Much of the rainfall in the southeast fell as a result of cold fronts late in the month, the passage of which was associated with severe weather for parts of South Australia, Victoria and southern New South Wales, including a significant storm surge which affected Melbourne on the 23rd. Victoria recorded the largest positive anomaly for June rainfall at 37% above average.

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 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 Tuesday 1 July 2014. 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.

The system used for calculating areal averages of rainfall was changed in May 2009; the main effect was that current and historical values for Tasmania were increased. Since December 2012, ACORN-SAT has been used for calculating areal averages of temperature; the major change from earlier datasets is that the ACORN-SAT dataset commences in 1910, and hence rankings are calculated using a larger set of years.
