South Australia in 2007
Warmest year since 1910, continuing a long run of above average temperatures, while long-term drought conditions continue with below average rainfall.

Summary

  • 2007 was the warmest year since 1910 for South Australia. State wide records commenced in 1910.
  • It is the 15th consecutive year of above average temperatures for South Australia.
  • Adelaide had it's warmest year in the 120 years record. Comparable temperature records started in 1887 in Adelaide.
  • Rainfall started well through to April, but winter-spring rainfall was very poor with the state having its driest such period on record.
  • The below average rainfall for 2007 continues the below average rainfall seen over the last ten years.

Rainfall

2007 began with many areas receiving very much above average rainfall amounts, with some locations recording their highest ever amounts during January, mainly due to an in-feed of tropical moisture from the northwest. However this was short lived, with February being a relatively dry month over the agricultural areas

For March & April most of the state received good rainfall, particularly over the agricultural districts. May's rainfall was quite patchy but mainly near average with only very few areas below average. This early rainfall gave the grain farmers hope of a good year, especially after the very poor year in 2006. However during June to October, most of the state recorded either below or very much below average rainfall amounts.

Though the rainfall over the state during 2007 was an improvement compared to 2006, the winter and growing season rainfalls have, once again, been significantly below average.

Adelaide's annual rainfall was 464.6 mm, 90.5mm below the normal of 555.1 mm. This is the 5th lowest annual rainfall at Kent Town and the 49th driest for Adelaide when the earlier records from West Terrace are included. The record lowest rainfall of 257.8 mm was set in 1967. The combined Adelaide rainfall record dates back 168 years to 1839.

The wettest overall station was Piccadilly with 1112mm followed by Woodhouse with 1062mm, and 1031 mm at Uraidla, all in the Mount Lofty Ranges district.

The driest overall was 68 mm at Marree Aerodrome, followed by 78 mm at Marree Township, both in the Far North district.

The wettest single day 149.0 mm at the Craddock (Yednalue), in the Upper North district, on 20th January, followed by 147.5 mm at Cordillo Downs, in the Far North district, on the following day.

Temperature

The mean temperature for South Australia for 2007 has been 1.1C above the 1961-1990 mean of 19.5C. This makes 2007 the warmest year for South Australia since state wide records began in 1910, and it is the 15th consecutive year that state-wide mean annual temperature have been above average. The previous warmest year was 2005 with annual mean temperature 1.0C above the 1961-1990 mean. Every month this year apart from January and June were above average for maximum temperature for the state.

Notes

This statement has been prepared based on information available at 11 am on Thursday 3 January 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.
