NSW in May 2013: Below average rain and warm days for NSW

  • Below average rainfall
  • Above average maximum temperatures, particularly in early May
  • Close to average minimum temperatures

Rainfall

NSW recorded a statewide average rainfall of 30.2 mm during May, below the historical average of 47.1 mm. Rain was close to normal across much of the state, with drier than normal conditions in parts of inland eastern NSW. Conditions were driest in the southeast, with the driest May on record at Cooma and the driest since 1947 at Bombala. The average rainfall across the Murray Darling Basin was 29.7 mm, also below the historical average of 42.3 mm and the driest May since 2008.

Surface troughs and associated cloudbands produced needed rain in inland NSW on 13-14 and 22-23 May, each of which produced widespread totals above 10 mm. An East Coast Low developed from the second system on the 23rd, resulting in widespread coastal totals above 25 mm for the 48 hours to 9am on the 25th. Totals were heaviest on the Mid North Coast, with a two-day total of 364.6 mm at Fishermans Reach, including 204.8 mm on the 24th.

Some sites had their lowest total May rainfall on record.

Temperature

The statewide average maximum temperature during May 2013 was 20.5 °C, 1.1 °C above the historical average and the warmest since 2008, with warmest temperatures in western NSW. Temperatures were well above average during the start of the month, with temperatures for 1-12 May more than 3 °C above normal across inland NSW. Several daily records were broken on the 1st, when temperatures reached 32.4 °C at Brewarrina Hospital. Maximum temperatures were generally average to below average during the remainder of the month, with Collarenebri recording its coldest day on record on the 22nd.

The statewide average minimum temperature was 7.5 °C, equal to the historical average. Nights were within 1 °C of average across most of the state, coolest in inland eastern NSW where conditions were driest, including the coldest May on record at Cooma. The mean temperature for May was consequently 13.9 °C, 0.5 °C above the historical average.

See a list of May temperature records.

Other phenomena

An East Coast Low on 24-25 May produced heavy rainfall and strong winds in coastal NSW, with wind gusts reaching 91 km/h at Murrurrundi Gap and 93 km/h at Byron Bay on the 24th.

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 10 am on Monday 3 June 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.
