Monday, 2 February 2009 - Monthly Climate Summary for South Australia - Product code IDCKGC13R0
Northeast of a line from Broken Hill to Tieyon (on the Northern Territory border) the rainfall was above average for January with some localised falls over 25 mm. For the remainder of the state the rainfall was mostly very much below average with many locations recording their lowest or equal lowest rainfall amounts for January. Many of these locations recorded no rainfall at all.
Rainfall over the pastoral districts was mostly very much below the January average with localised pockets of above average readings. Rainfall totals were mostly less than 2 mm with large areas receiving no rain, but in the far northeastern areas there were rainfall recordings of between 5 and 20 mm.
The highest total was 28.0 mm at Arkaroola in the Northeast Pastoral district, which was also the highest for the state.
Rainfalls over the agricultural districts were predominantly very much below average with many places recording no rainfall, equalling their lowest recorded rainfall for January. The majority of rainfall amounts were less than 2 mm with only a small number of places with between 5 and 10 mm, which mostly resulted from thunderstorms in the Lower North and Lower Southeast districts.
Some sites had their lowest total January rainfall on record.
Maximum and minimum temperatures were, on the whole, above average with some agricultural areas recording average minimum temperatures just below average for January. The month started with mild conditions but most of the state, during the last week of the month, endured a heatwave, with maximum temperatures above 45°C being recorded at many locations. Several places recorded their highest January daily maximum temperature on record during this event: Mount Gambier (43.6°C), Murray Bridge (46.6°C), and Mount Barker (44.5°C).
Murray Bridge, Mount Barker and Ceduna also recorded their highest daily overnight minimum temperature for January. Adelaide's overnight minimum of 33.9°C on the 29th January is the highest for any month since comparable temperature records began in Adelaide in 1887.
Mean maximum temperatures over the pastoral districts of the state were 1.5 to 2.5°C above average, with mean maximum temperatures ranging from 35.3°C at Yunta in the North East district to 40.3°C at Marree in the Far North district.

This statement has been prepared based on information available at 9 am on Monday 2 February 2009. 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
(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.
