Australia in June 2012

In Brief

June rainfall was mixed across the country. Rainfall was generally below average for parts of central Australia as well as along the NSW-Victoria border; rainfall was generally above average across Queensland, the coastal southeast, and parts of southwest WA. Maximum temperatures were generally above average across southern WA, and below average for most of Queensland and the northern half of the NT. Minimum temperatures were above average in western WA and southeast Queensland. Minimum temperatures were below average across most of the north, SA, the western half of NSW, and and most of northern Victoria.


Temperatures

Averaged over Australia, maximum temperatures were somewhat below average for June, with a national anomaly of −0.27 °C. The NT and Queensland recorded the coolest June maximum anomalies, with −0.85 °C and −0.81 °C, respectively. For Australia as a whole, June minimum temperatures well below average; at 0.94 °C below average it was the 12th-coolest year on record. Queensland and SA recorded minima 0.91 °C and 0.88 °C below average, respectively. For the NT it was the second-coolest June on record, with an anomaly of −2.31 °C. Tasmania was the only State to record a positive minimum temperature anomaly, with +0.37 °C.

Maximum temperatures were generally above average across the southern half of WA, a small area of the Riverina in NSW, and a small area of Queensland's Cape York Peninsula north of Cape Melville. Maximum temperatures were below average for most of Queensland and the northern half of the NT, as well as small scattered areas of the southeast mainland.

Minimum temperatures were also above average for part of WA along the western coast and adjacent inland, and also in southeast Queensland. Minimum temperatures were below average across most of the north and central Australia, as well as the majority of SA, the western half of NSW, and northern and north-western Victoria. Minimum temperatures were very much below average across (i.e. in decile 1, the lowest 10% of records) much of the north; June minima 2 to 5 degrees below average were widespread across the tropical north, with the coolest anomalies recorded inland south of the Gulf of Carpentaria and in the Kimberley and Victoria River Districts around the WA-NT border.

*Anomaly is the departure from the long-term (1961–1990) average.
A fractional rank indicates that the value is tied for that rank.

Rainfall

In a similar pattern to May, June saw above average rainfall across the northeast of the country, and some respite from below-average rainfall in the south with much of this area receiving average rainfall. Averaged over Australia, June rainfall was 4% above average, ranking as the 52nd-wettest year in 113 years of record. Averaged across Queensland, rainfall was 75% above average for the month of June, ranking as the 26th-wettest year on record.

Rainfall was below average for parts of the tropical eastern coast, and inland southern NSW and northern Victoria around the border. Much of northern and central Australia received little or no rainfall during June, as is typical of the northern dry season. Rainfall was above or very much above average for coastal regions in the southeast, most of Queensland and adjacent north-eastern SA, the Roper-McArthur district of the NT, and scattered areas of WA, mostly in the southwest.

Notes

The Seasonal 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.

This statement has been prepared based on information available at 12 noon EST on Monday 02 July 2012. 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.

In the tables, fractional ranks denote tied values.

A new area-averaging method was adopted for rainfall in May 2009. Current and historical totals for Tasmania are substantially higher than under the old scheme, but differences for other states, and nationally, are negligible. The rankings and departures from mean shown here use the new method.
