Australia in November 2012

In Brief

November rainfall was average to below average across most of eastern Australia and South Australia, with much of the eastern Northern Territory and Western Australia recording above-average rainfall. Despite these spatial differences, for Australia as a whole the monthly rainfall total was near average. Maximum temperatures were above average for most of Australia and in the highest 10% of records for western Tasmania, SA, and adjoining parts of the surrounding States. A large area of northeastern SA recorded its highest November monthly maximum temperature. Small parts of WA were the only regions to record below-average daytime temperatures. November minimum temperatures were generally above average for Australia, with near-average monthly minima recorded in similar locations to maxima (western WA, parts of the north, and much of eastern Queensland). An area around Mackay on the Queensland coast was the only region to record below-average monthly minima.


The November-averaged maximum temperature was the fourth-highest on record for Australia as a whole. The national anomaly was +1.73 °C; all States and the NT recorded a monthly maxima more than 1 °C above the long term average. Queensland's monthly anomaly was also its fourth highest (+1.50 °C), Tasmania's third highest (+2.30 °C), while SA its second highest and the largest anomaly for any State (+3.07 °C).

Maximum temperatures were above average for most of Australia. Maxima were near average in a narrow strip along the eastern coast in New South Wales and Queensland as well as parts of northern Australia and most of the western half of WA. Small parts of WA in the Central Wheat Belt and near Karratha were the only regions to record below-average daytime temperatures. A large part of the interior and southern Australia between southeastern WA and western Victoria as well as western Tasmania recorded maxima in the highest 10% of records. Anomalies were 3 to 5 °C above average across much of this area and was the highest-on-record November-averaged maximum temperature for a large area of northeastern SA.

Exceptional heat across central and southeastern Australia in the last week of the month contributed to these anomalies. During this event numerous stations recorded their hottest November day, including 45.8 °C at Ouyen in Victoria's Mallee, breaking the previous Victorian record (see the Special Climate Statement to be released shortly for full details.)

The national-average monthly minimum temperature was also above average (anomaly of +0.83 °C), and above for each individual State. Minima for most of central and southern Australia were above average, with the most significant anomalies extending in a band southeastwards from the Kimberley/Pilbara coast to NSW and East Gippsland. Anomalies were 2 to 4 °C above average across most of central Australia for the month. For SA, minima were 1.83 °C above average, the fourth-highest November anomaly on record. Although no state recorded a below-average monthly minimum temperature, the NT, Queensland, and WA recorded lower anomalies than the other States, reflecting the near-average minima recorded across most of eastern Queensland, western WA, the Kimberley, and the central NT.

November rainfall totals were below average across large areas of eastern Australia, SA, and the eastern Top End although the areas receiving below-average rainfall were non-contiguous. There were numerous isolated areas of lowest-on-record rainfall distributed amongst the patchy negative rainfall anomalies. The Kimberley, eastern NT, and most of WA south of Port Hedland recorded above- to very-much-above average rainfall. The nationally-averaged total was close to average, concealing these marked differences in rainfall; the national average was 8% below average while WA's total was 88% above average and SA's was the lowest since 1996 (54% below average).

While light falls were widespread across parts of the Kimberley and NT, isolated moderate to heavy falls brought small areas to the highest 10% of records. Falls in southern WA were more substantial, reaching 25 to 50 mm above the November average in much of the region, and exceeding 50 mm above average in parts of the Interior and southern hinterlands.

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.

This statement has been prepared based on information available at 12 noon EST on Monday 3 December 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.
