Tuesday, 1 April 2014 - Monthly Climate Summary for South Australia - Product code IDCKGC23R0
March started with warmer than average temperatures across most of the State, cooler days and nights mostly occurred through the second half of the month following the passage of a cold front that extended from a deep low pressure complex to the south of the State. Most rainfall around the State was recorded in the wake of the front, with more rainfall being recorded at the end of the month as a upper level cold pool and a trough of low pressure near the eastern border brought a humid and unstable airmass over eastern and central parts of the State.
March was mostly dry across South Australia until a cold front extending from a deep low pressure complex to the south of the State moved over southern districts on the 15th. A band of middle level cloud produced gusty thundery showers near and ahead of the front. More rainfall was recorded over eastern and central districts at the end of the month as an upper level cold pool and a trough of low pressure near the eastern border brought a humid and unstable airmass over eastern and central parts of the State.
These systems resulted in average to above average rainfall totals for locations across eastern districts. Large parts in the west and north of the State recorded very much below average rainfall with some sites having their lowest total March rainfall on record and other sites having their lowest total March rainfall for at least 20 years. Rainfall totals averaged across the South Australia as a whole ranked 27th highest out of 115 years of observations.
Rainfall totals typically ranged from 20 to 50 mm across the eastern areas, with lower monthly totals of 5 to 10 mm across central areas while the northwest of the State received little or no rain throughout the month.
The wettest location in the state was at Gammon Ranges (The Plateau) where 61.2 mm was recorded for the month, more than half which was observed on the 7th from showers and thunderstorms that were observed about the Flinders Ranges
Despite a milder finish to the month, March 2014 started with above average temperatures across most locations. March temperatures averaged across the whole of South Australia were 0.9 °C warmer than average. By comparison, March 2013 was 1.2 °C warmer than average.
Monthly mean maximum temperatures, were up to 2 °C above average across pastoral districts but nearer average and up to 1 °C above average across agricultral parts. Averaged across the State and month as a whole days were 1.2 °C warmer than average, which ranks as South Australia's 28th warmest March days out of 105 years of observations.
The hottest location on average for the month was at Marree Comparison where the maximum temperatures averaged 35.6 °C for the month which results in the highest March mean daily maximum temperature for 22 years at this location. In contrast, Cape Willoughby on Kangaroo Island was the coolest location for the month for daytime temperatures with maximum temperatures averaging 20.7 °C.
The hottest day was recorded at Marree Comparison on 10 March where the temperature reached 41.0 °C. Mount Lofty in the Mount Lofty Ranges reached 13.6 °C on the 25 March, resulting in the coolest day for any location in the State.
Monthly mean minimum temperatures, were 2 to 3 °C above average across pastoral districts, but nearer average and as low as 1 °C cooler than average across southern agricultral parts. Averaged across the State and month as a whole nights were 0.6 °C warmer than average, which ranks as South Australia's 28th warmest March nights out of 105 years of observations.
The warmest nights on average for any location were at Moomba where the minimum temperatures averaged 21.1 °C for the month. In contrast, Padthaway South had the coolest nights for the month with minimum temperatures averaging 9.4 °C.
The warmest night was recorded at Oodnadatta on 15 March where the temperature dropped to just 27.9 °C. Keith (Munkora) dropped to 0.7 °C on 22 March, resulting in the coolest night for any location in the State.

A Monthly Climate Summary is prepared to list the main features of the weather in South Australia using the most timely and accurate information available on the date of publication; it will generally not be updated. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review, usually published in the fourth week of the month.
This statement has been prepared based on information available at 8 am on Tuesday 1 April 2014. 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.
