South Australia in September 2014: A warm and dry start to spring

Maximum temperatures were generally above average across South Australia during September, with coastal districts experiencing daytime temperatures that were very much above average for the month. Across the state as whole, the September maximum temperature was 2.2°C above the long term average. While minimum temperatures were 1.0°C above the long term average for the state, some eastern districts observed cooler than average nights, particululary during the third week of the month. In the last week of the month, strong to gale force northerly winds ahead of cold front saw several locations observe both day and night temperatures that were significantly above average, with several locations throughout coastal and southeast districts observing highest on record daily September minimum temperatures.

Rainfall was very much below average across most of the state, though tended average to above average for some locations in the northeast Pastoral districts, continuing a pattern that became established during the final weeks of winter. The heaviest rainfall occurred on the 24th of the month as a low pressure trough with embedded thunderstorms crossed central and eastern districts. Isolated showers cleared by the afternoon of the 25th. Very little rainfall was recorded during other periods of the month which resulted in a statewide monthly average that was 57% below the long term average.

  • A warm spell at months end results in record warm nights
  • Below average rainfall for most of the state
  • Daytime temperatures above average

Notes

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

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

This statement has been prepared based on information available at 10 am on Wednesday 1 October 2014. 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.
