Adelaide in March 2015: Driest March in more than 20 years; cooler than average temperatures

A lack of tropical activity feeding moisture across South Australia throughout March resulted in another very dry month across the Adelaide region. There were just 3 days with any measureable rain at Kent Town, totalling just 2.4 mm (2.8 mm in the manual gauge). This has resulted in Adelaide having its driest March since 1994 (21 years ago with 0 mm recorded). The lack of significant rainfall was evident across the wider Adelaide region with several other sites having their lowest total March rainfall since 1994.

Cooler winds from the southwest dominated the month resulted in cooler temperatures throughout much of March across the Adelaide region. Maximum temperatures averaged across the month were more than 1 °C cooler than average. Adelaide experienced 4 days with a maximum temperature exceeding 30 °C; typically the city can expect around 8 days of maximum temperature greater than 30 °C during March. The lack of very warm days resulted in Adelaide having it coolest March with respect to daytime temperatures since 2011.

Night time temperatures also tended to be cooler than average, particularly at the end of the month, when the city observed its coldest March night in 7 years, with the overnight temperature at Kent Town dropping to 9.2 °C on the 28th. The cool nights resulted in Adelaide having it coolest March nights on average in 10 years.

  • Adelaide's driest March in 21 years
  • Adelaide's coolest March nights in 10 years
  • Adelaide's coolest March days in 4 years

Notes

A Monthly Climate Summary is prepared to list the main features of the weather in Adelaide 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.

A Climate Summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 12 pm on Wednesday 1 April 2015. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages for individual sites 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 10 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 decile ranking (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.

The ACORN-SAT dataset is used for temperature area averages.
