Most values are the precipitation in the 24 hours to 9 am on the day indicated. Days marked with → are part of a longer accumulation, which is shown on the final day.
Values over 100 mm have been rounded to the nearest whole millimetre.
Days marked with - have a rainfall report of zero; days left blank have no rainfall report (which often indicates no rain fell).

Notes

The Monthly climate summary, usually published in the first week of the following month, lists the main features of the weather in Greater Adelaide using the most timely and accurate information available on the date of publication; it will generally not be updated.

This summary includes data from observing sites in or near the Greater Adelaide “Greater Capital City Statistical Area” (GCCSA). The Australian Bureau of Statistics designed the GCCSAs to represent a socio-economic definition of each capital city. This means the greater capital city boundary includes people who regularly socialise, shop or work within the capital city, but live in the small towns and rural areas surrounding the capital city. It does not define the built up edge of the capital city.

This statement has been prepared based on information available on Sunday 4 October 2026. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

In some situations, some or all of the rainfall is in the form of hail or snow. In these cases, the totals given are for the water equivalent: the depth of liquid water that results from melting any frozen precipitation. There can be significant 'undercatch' of snow in strong winds, meaning the true precipitation can be higher than that reported.

Averages for individual sites are long-term means based on observations from all available years of record, excluding the current year. The length of record can vary widely from site to site. Averages are not shown for sites with fewer 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.

Where temperature area averages are mentioned, they are derived from the ACORN-SAT dataset.
