South Australia in July 2013: Wet and warm conditions for the State

  • Wet conditions continue for agricultural areas with record daily and monthly totals.
  • State-wide maximum temperatures mostly above average with new daily records.
  • Warmest July nights in 38 years at Kent Town and warmest July days in 11 years

Rainfall

South Australia received rainfall above the long-term average July total for the State as a whole, resulting in the wettest July since 2006. Apart from the northwest pastoral district, where rainfall was average to below average, most locations recorded a wetter than average July. Parts of the Upper North and Flinders Ranges observed new record high July total rainfall. The wettest periods for most districts occurred between the 5th and 8th, between the 13th and 15th and between the 18th and 23rd. The heaviest falls were reported through the latter periods as low pressure systems located over the Great Australian Bight extended rain bands across southern parts of South Australia.  Several locations in the western agricultural and pastoral areas observed new record-high daily rainfall totals associated with the event on the 13th. The passage of another low pressure system late in the month resulted in scattered showers and isolated thunderstorms across the agricultural areas, with isolated showers further north. The cold southerly airstream associated with the low also produced light snowfall across parts of the Mount Lofty Ranges on the 20th.  

Pastoral Districts

Rainfall totals over the pastoral districts were mostly average to above average though tending below average in the far Northeast. Totals typically ranged between 10 and 25 mm, with higher totals in excess of 50mm for southern parts of the pastoral areas. The wettest overall in the pastoral districts was at Yardea in the Northwest, with 93.2 mm; 38 mm of which was observed in the 24 hours to 9am on the 13th. Moonaree (Kangaroo Well), located in the southern part of the Northwest district, reported the wettest day for any location across the State, with 46.6 mm observed on the 13th.

Agricultural Districts

Most parts of the agricultural areas reported above-average rainfall throughout the month, particularly across western and coastal areas. Totals were in the range of 25 to 50mm across northern parts of the agricultural areas and in the 50 to100 mm range across large parts of the Eyre and Yorke peninsulas, the Mount Lofty and Flinders ranges and across the Murray Valley districts. Locations across Kangaroo Island, the Mount Lofty Ranges, the lower Southeast and the southern tips of the Eyre and Yorke peninsulas, observed monthly rainfall totals in the 100 mm to 200 mm range. The wettest overall for the month in the agricultural districts was at Uraidla in the Mount Lofty Ranges, reporting 293.6 mm for month; nearly half of which was observed between the 18th and 23rd.

Some sites had their highest total July rainfall on record. Some sites had their highest total July rainfall for at least 20 years. Some sites had their lowest total July rainfall on record. Some sites had their highest July daily rainfall on record.

Temperature

The mean temperature (the average of the maximum and minimum temperatures) for South Australia as a whole in July 2013 was 1.2 °C above the long-term average. Mean temperatures at particular stations ranged from 8.3 °C at Mount Lofty to 14.7 °C at Moomba Airport in the Far North district. Some sites had their highest July mean temperature on record. Some sites had their highest July mean temperature for at least 20 years.

Maximum Temperature

Mean maximum temperatures over South Australia were generally above average across the State throughout July, particularly in the pastoral districts. Across the State as a whole, monthly maximum temperatures were 1.4 °C above the long-term average and the warmest since 2007. Some locations were as much as 1.5 °C above average across northern parts of the State. Agricultural regions observed daytime temperatures closer to the average. Average daily maximum temperatures ranged from 10.3 °C at Mount Lofty to 22.3 °C at Moomba Airport in the Far North district.

The coldest periods for many locations occurred through the third week of July as low pressure and cold frontal systems crossed the State. Mount Lofty recorded the coldest day of the month when its maximum temperature only reached 5.5 °C on the 20th. 

The warmest day for much of the State occurred during the second and the last week of July in the northerly airstream ahead of a low pressure trough. Moomba Airport observed the hottest day for any location in the State, reaching 30.9 °C on the 13th.

Some sites had their highest July mean temperature on record. Some sites had their highest July mean temperature for at least 20 years.

Minimum Temperature

Mean minimum temperatures were widely above average across South Australia through July; with a State-wide anomaly 1.2 °C above average, July 2013 is the warmest since 2009. The warmest part of the State with respect to minimum temperatures was across the far north of the Northwest district and through the southeast of the State where minimum temperatures were up to 2 °C warmer than average.

The warmest nights for most of South Australia occurred during the second and third week of July. Moomba Airport observed the warmest night for any location in the State on the 18th, with a minimum of 16.2 °C. Gluepot Reserve, in the Northeast district, observed the coldest night with a minimum of –4.9 °C on the 10th.

The warmest nights on average were observed at Neptune Island with 12.3 °C, while Arkaroola observed the coolest nights on average with a monthly average of 3.0 °C.  

Some sites had their warmest July night (highest daily minimum temperature) on record. Some sites had their highest July mean daily minimum temperature on record. Some sites had their highest July mean daily minimum temperature for at least 20 years.

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.

This statement has been prepared based on information available at 11 am on Thursday 1 August 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.
