South Australia in July 2008
Near rainfall average in the south, drier in the north.

Summary

  • Despite some cold and frosty periods, temperatures were generally near normal when averaged across the month.
  • Rainfall was generally near average, and many locations in mainly coastal areas and in the Mount Lofty Ranges ended up with above average rainfall for the month in a predominately westerly air-stream. Rainfall tended below average in the central and eastern pastoral areas.
  • Rainfall totals for the year to date still remain below average across much of the state. This is also the case to a lesser extent for the April to end of July rainfall totals, as representing the growing season rainfall to date.

Rainfall

Pastoral Districts

Rainfall totals were near average in the west tending below to very much below average in central and eastern areas.

Rainfall totals were typically 5 to 10 mm, apart from the northern and northeastern areas were some locations recorded no rainfall for the month. Gluepot in the Northeast Pastoral area recorded 21.5 mm, the highest amount in the Pastoral Districts.

Agricultural Districts

Rainfall totals were generally near average across the agricultural areas. Above average rainfall totals tended to be in coastal and ranges areas exposed to what was a predominately west to southwest air-stream through the month.

Most of the agricultural areas received totals in the 50 to 80 mm range tending to 20 to 30 mm in the northern parts.

Many locations on Kangaroo Island and in the lower South East and the Mount Lofty Ranges saw totals exceeding 100 mm. The highest total for the state was 263 mm at Woodhouse (Piccadilly).

Across the longer term, rainfall for the growing season to date is generally below average across South Australia, and for the year to date. Longer term rainfall deficiencies continue across 2 to 10 year rainfall averages for the South Australian agricultural areas and the Murray Darling Basin.

Temperature

State-wide the monthly mean July temperature (the average of the maximum and minimum temperatures) was 0.01 degrees above the average for the South Australian agricultural areas, and 0.6°C above average for South Australia as a whole, looking at the July records since 1910.

Maximum

Mean maximum temperatures for July were near to below average in the central and eastern agricultural areas, generally up to 1°C below average, and generally up to 2°C above average over the remaining agricultural areas and the pastoral districts.

In the Pastoral districts mean maximum temperatures ranged from 14.7°C at Yunta to 20.5°C at Oodnadatta Airport.

Mean maximum temperatures over the Agricultural districts ranged from 10.4°C at Mt Crawford in the Mount Lofty Ranges to 18.1°C at Ceduna in the Western Agricultural district.

The highest maximum recorded during July was 30.6°C at Oodnadatta Airport on the 31st of July. The lowest was 6.2°C at Mount Crawford on the 7th of July.

Minimum

Mean minimum temperatures for July were generally near or up to 1°C below average in the east tending to near and up to 1°C above average in the west and north of the state.

Mean minimum temperatures ranged from 2.3°C at Yunta Airport to 6.3°C at Coober Pedy Airport.

Over the Agricultural districts mean monthly minimum temperatures ranged from 1.9°C at Yongala to 11.2°C at Neptune Island.

The lowest minimum temperature recorded during July was −5.8°C at Yunta in the North East Pastoral district on the 24th. Streaky bay recorded the warmest overnight temperature with 13.9°C on the 1st of July.

Notes

This statement has been prepared based on information available at 5 pm on Friday 1 August 2008. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Normals 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 "normal" 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, normal in decile 4 to 7, high in decile 8 or 9 and very high is in decile 10).
The Fraction of normal shows how much rain has fallen this time as a percentage of the long-term mean.
