Friday, 29 February 2008 - Monthly Climate Summary for South Australia - Product code IDCKGC13R0
Rainfall tended to be below average across South Australia, particularly in the east of the state, while other states generally saw good falls from the ongoing La Nina event.
Temperatures were generally below average across the state in a cooler southerly air-stream. This was due to persistent high pressure systems to the southwest of the Great Australian Bight, and increased cloudiness from the La Nina event. As a result some locations had record lowest daily maximum temperatures for February.
Rainfall over the Pastoral Districts was near to below average.
Some locations in the centre of the state received above average falls in thunderstorm activity near the start of the month.
Rainfall totals were generally less than 5 mm, with Marla, Andamooka and Yunta (Melton) receiving no rainfall for the month.
The highest rainfall total was 34.9 mm at Mount Eba in the North West District.
Rainfall totals over the Agricultural Districts were near average, tending to below average in the east and were typically less than 5 mm, though the Mt Lofty ranges, the South East, Kangaroo Island, and parts of the Eyre Peninsula saw totals more consistently in the 10−15 mm range.
The highest rainfall reported in the Agricultural Districts was 28.4 mm at Parawa on the Fleurieu Peninsula.
Mean maximum temperatures were generally 1 to 2°C below average across the state for February 2008.
This is in contrast to last years warmest February in the area averaged record for South Australia, which runs since 1950.
Mean maximum temperatures across the Pastoral Districts ranged from 29.7°C at Yunta in the Northeast Pastoral district to 35.3°C at Marree Comparison in the Far North Pastoral district.
Moomba Airport recorded the highest daily maximum for the month with 43.3°C on the 22nd. Nonning recorded the coolest with 21.4°C on the 22nd.
Both figures were associated with the passage of a cold front during that day.
Mean maximum temperatures across the Agricultural Districts ranged from 20.0°C at Cape Willoughby on Kangaroo Island, to 31.3°C at Hawker in the Upper North district.
Murray Bridge Comparison recorded the highest maximum across the agricultural areas with 40.7°C on the 19th.

This statement has been prepared based on information available at 1 pm on Friday 29 February 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
(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.
