New South Wales in May 2015: Dry in the south, wet in the north

  • Below average rainfall, particularly in the south
  • East coast low causes heavy rain on the north coast
  • Close to average temperatures

The NSW statewide average rainfall was 13% below the historical average during May. Rainfall was well above average on the northeast coast and parts of northern inland NSW, but generally average to below average rainfall in the southern half of the state. The most significant rainfall event occurred at the start of the month, when an east coast low developed in a coastal surface trough near the Queensland border. This caused rainfall totals above 100 mm across much of the north coast on the 2nd, reaching 217 mm at Kalang. A cold front and surface trough also caused rain and storms in inland NSW over the 19th and 20th, with a low pressure system developing from the trough and causing additional coastal rain over the 21st and 22nd.

The statewide average maximum temperature was 0.2 °C above average, with close to average maximum temperatures across most of the state. Minimum temperatures were 0.7 °C above average for the state as a whole, with nights more than 1 °C above average in the Hunter, Mid North Coast, and adjacent areas of inland northeastern NSW. Temperatures were warmest at the start of the month, with some stations in the Sydney and Hunter regions recording their warmest May night on record on the 3rd, while parts of the south coast experienced their warmest May day on record on the 5th. The month ended with a cold front and southerly winds that brought cool temperatures across the state.

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.

A Climate Summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 11 am on Monday 1 June 2015. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages for individual sites 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 10 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 used for temperature area averages.
