New South Wales in January 2013: A month of extremes

  • Third warmest January on record
  • Persistent and widespread heatwave
  • A very dry January for inland NSW
  • Ex-Tropical Cyclone Oswald delivers heavy rain in the northeast

Rainfall

NSW recorded a statewide average rainfall of 56.19 mm during January, below the historical average of 65.59 mm. Rainfall was above average in northeast and coastal NSW but generally below to very-much-below average across inland NSW. The Murray-Darling Basin recorded 36.49 mm duing January, well below the historical average of 55.14 mm and the driest since 2009.

For much of the month NSW had received little rain, with only light and very patchy rain recoded due to frontal activity. On 26 January ex-TC Oswald had moved far enough south to bring rain to northeast NSW. Widespread heavy fell from 27-29 January as the system moved south across coastal NSW. The rainfall resulted in minor to major flooding aross the Northern Rivers, Mid North Coast and Hunter regions. The highest daily rainfall recroded during the event was 348 mm at Boat Harbour (Rous River) on the 28th, with Uki recording 641 mm in the four days to 29 January. For further information on ex-TC Oswald (see Special Climate Statement 44).

Some sites had their highest total January rainfall on record, while others had their lowest total January rainfall on record.

Temperature

NSW recorded a statewide average maximum temperature of 35.34 °C during January, 3.66 °C above the historical average. This is the third warmest January since records began in 1910, and the warmest for NSW since 1939. Temperatures were above average across the state, with average daytime temperatures more than 3-6 °C above normal across the majority of inland NSW. The extreme heat was the result of a heatwave that affected much of Australia over a prolonged period (see Special Climate Statement 43).

The statewide average minimum temperature was 19.61 °C, 1.92 °C above the historical average. This was the ninth-warmest on record for NSW, and the warmest January since 2006. Nights were particularly warm on the 18th, when much of inland NSW was more than 8 °C above normal with parts of the Hunter and South West Slopes and Plains recording their warmest January nights on record.

The statewide average temperature was consequently 2.82 °C above average, the fifth-warmest January for NSW since records began in 1910 and the warmest January since 2006.

See a list of January temperature records.

Other phenomena

Thunderstorms were prevalent across NSW during January with several periods of intense widespread thunderstorm activity on the 5th to 6th, 12th to 13th, 18 to 24th and 27th to 28th each associated with frontal activity. Most of this thunderstorm activity was associated with little to no rainfall and was responsible for igniting fires in the areas affected. The frontal activity, which triggered the thunderstorms also generated strong winds with 107 km/h at Cabramurra SMHEA AWS on the 8th, with 128 km/h recorded at Narrabri Airport AWS on the 13th and 115 km/h recorded at Kiama (Bombo Headland) on the 18th.

The major feature for January was ex-TC Oswald, which affected the northeast and coastal NSW from the 26th through to the 29th. The system saw winds reach 131 km/h at Byron Bay (Cape Byron AWS) on the 28th and widespread minor to moderate flooding in the Northern Rivers, Mid North Coast and Hunter catchments, with major flooding experienced in the Clarence River catchment. At Grafton (Prince St), the Clarence River reached a new record flood height of 8.1m, surpassing the previous record of 7.9m set in 1890.

Notes

A Monthly Climate Summary is prepared to list the main features of the weather in New South Wales 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.

This statement has been prepared based on information available at 9 am on Friday 1 February 2013. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages are long-term means based on observations from all available years of record, which vary widely from site to site. They are not shown for sites with less than 20 years of record, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of long-term average rain.

The Rank indicates how rainfall this time compares with the climate record for the site, based on the decile ranking (very low rainfall is in decile 1, low in decile 2 or 3, average in decile 4 to 7, high in decile 8 or 9 and very high is in decile 10).
The Fraction of average shows how much rain has fallen this time as a percentage of the long-term mean.

The ACORN-SAT dataset is being used for temperature area averages from December 2012 onwards. The major change from earlier datasets is that the ACORN-SAT dataset commences in 1910, rather than 1950, and hence rankings are calculated using a larger set of years.
