South Australia in Autumn 2008
A dry Autumn with warm days and cool nights.

Summary

  • Autumn rainfall was generally below average, apart from the Mid North, the Adelaide region and the Lower Southeast.
  • Autumn temperatures started well above average in a widespread heatwave in the first half of March, then days remained warmer than average under clearer skies, while cool nights prevailed for the rest of the season.
  • Ceduna and Streaky Bay had their warmest Autumn's on record.

Rainfall

Pastoral Districts

Rainfall was generally below average across the Pastoral Districts this Autumn, at a time of year when rainfall is low on average, and rainfall totals tended to be less than 10 mm.

The highest Autumn rainfall total was 26.1 mm at Blinman in the far North, when the average for that location would normally be 66 mm.

Agricultural Districts

Rainfall totals were generally below average, apart from much of the Mid North, the Adelaide Plains and the Mount Lofty Ranges where rainfall was above average.

Rainfall totals over 200 mm were recorded at several locations in the Mount Lofty Ranges, with the highest being 295 mm at Ashton (Marble Hill), but were typically 100 to 200 mm.

Totals across the Adelaide Plains, the Lower Southeast and the Mid North districts were typically 50 to 150 mm. Remaining districts generally had totals of 20 to 80 mm.

See a map of rainfall deciles.

Temperature

The season started significantly warmer than average through until mid-March, with a persistent high pressure pattern in the Tasman Sea maintaining a northerly air-stream across South Australia. Many locations had record length heatwaves through the period. For more details see the Special Climate Statement of the event here…

Temperatures returned closer to average through the remainder of the season, but clear skies and persistent high pressures systems still meant warmer than average daytime temperatures, while nights were cool with light winds. This meant that Ceduna and Streaky Bay in the Western Agricultural district had their warmest Autumn's on record.

Mean Autumn maximums were generally 1 to 2°C degree above average. Mean minimum temperatures generally within 1°C degree above average in the west of the state, and within 1°C degree below average in the east, due to persistent high pressure systems producing clear nights with light winds.

The hottest autumn day was 42.7°C recorded at Kyancutta on the 8th March, and Ceduna and Nullarbor on the 9th March. The coldest daily maximum was Mount Crawford on the 27th of April when a maximum of 9.5°C was recorded. The lowest daily minimum temperature recorded was at Yunta on the 29th May when −1.4°C was recorded.

Marree had the warmest Autumn mean maximum temperature of 29.5°C. The lowest mean maximum Autumn temperature was 19.8°C at Robe.

The warmest nights on average across autumn were recorded on Neptune Island with 15.5°C, while the coldest nights on average were recorded at both Coonawarra in the Lower South East and Yongala in the Far North, both averaging 7.9°C for the season.

Notes

This statement has been prepared based on information available at 3 pm on Monday 2 June 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.
