Monday, 3 March, 2014 — Monthly Summary for Australia — Product Code IDCKGC1A00
February saw above-average maximum temperatures recorded across the southeast, extending into southeastern Queensland and eastern South Australia, as well as along the western coast of Western Australia. Minima were warmer than average over a similar area, although extending further into southern South Australia. Maxima were below average across most of northern Australia and the east of Western Australia while minima were below average over a smaller area around the Western Australia–Northern Territory border. The national maximum temperature anomaly, −0.45 °C, and minimum temperature anomaly, +0.14 °C, combined to give a mean temperature anomaly of −0.16 °C.
Rainfall was above average nationally (33% above average) during February, although below-average rainfall was recorded in much of Victoria, southeast Queensland and northeastern New South Wales, northern Tasmania and across the western half of Western Australia. Rainfall across the remainder of the country was generally above average.
February was a warm month for southeast Australia and the west of Western Australia although it was cooler than average for much of the north and the southeast of Western Australia. The national area-averaged maximum temperature anomaly was −0.45 °C. The minimum temperature anomaly was +0.14 °C and the mean temperature anomaly −0.16 °C.
Queensland, the Northern Territory and Western Australia recorded below-average maximum temperatures, largely correlating with areas of above- to very-much-above-average rainfall. A large are in the central Northern Territory, extending into adjacent parts of Western Australia, and the west of the Cape York Peninsula recorded maxima in the lowest 10% of records. For the Northern Territory as a whole February maxima were the 11th-coolest on record, at 2.34 °C below average. Maxima were also cooler than average in the eastern half of Western Australia.
Maxima were above to very much above average along the west coast of Western Australia and across southeastern Australia, including Tasmania, and extending into southeastern Queensland and the Northeastern Pastoral and Lower Southeast districts of South Australia. February maxima were the 10th-warmest on record for Victoria, 11th-warmest for Tasmania and 16th-warmest for New South Wales; all three states recorded maximum temperatures more than 1.43 °C warmer than average.
Minimum temperatures were above average for most of the west coast of Western Australia and across southern and northeastern South Australia, the southeast including Tasmania and southern Queensland as well as a small area in inland western Queensland. Minima were below average for an area of eastern Queensland inland of Mackay and for a large area extending from the centre of the Northern Territory into Western Australia in the eastern Kimberley and south to the area around Giles.
|Areal average temperatures|
|Maximum Temperature||Minimum Temperature||Mean Temperature|
|New South Wales||90||+1.60||93||+1.39||92||+1.50|
|South Australia||= 68||+0.52||84||+0.85||76||+0.69|
|Northern Territory||11||−2.34||= 22||−0.75||13||−1.54|
Rank ranges from 1 (lowest) to 105 (highest). A rank marked with ’=‘ indicates the value is tied for that rank. Anomaly is the departure from the long-term (1961–1990) average.
Nationally-averaged rainfall during February was 33% above the long-term average, and was the 91st-wettest February in 115 years of record. Rainfall was above average over the tropical north, with highest-on-record rainfall in an area on the western coast of the Cape York Peninsula mainly as a result of very heavy rain early in the month. Rainfall was also above average across much of western Queensland, through Western Australia from the western Kimberley to the Nullarbor coast and through much of South Australia extending into the western half of New South Wales and northwestern Victoria. Rainfall was below average in southern and eastern Victoria, northern Tasmania, northeastern New South Wales and southeastern Queensland, extending as far north as Emerald, and in the Pilbara and northern Gascoyne and South West Land Division in Western Australia.
Victoria recorded the largest departure for below-average rainfall, at 31% below the February average for the state as a whole, while South Australia recorded the largest positive departure at 78% above average.
Notable heavy rainfall events during February included Adelaide's wettest day in over 45 years and equal-fifth wettest day on record when 75.2 mm fell in the 24 hours to 9 am on the 14th; Canberra receiving its average monthly total in a three-hour period on the afternoon of the 19th, and heavy rain early in the month in Queensland around the Gulf coast and between Longreach and Emerald seeing monthly records broken well before February was over.
|New South Wales||67||47.7||−6%|
Rank ranges from 1 (lowest) to 115 (highest). A rank marked with ’=‘ indicates the value is tied for that rank. Departure from mean is relative to the long-term (1961–1990) average.

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 10 am EST on Monday 3 March 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.
