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, generally published on the first working day of each month, lists the main features of the weather in Greater Perth using the most timely and accurate information available on the date of publication; it will generally not be updated. More extensive discussion of significant weather events, along with later information and data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review.
This summary includes data from observing sites in or near the Greater Perth “Greater Capital City Statistical Area” (GCCSA). The Australian Bureau of Statistics designed the GCCSAs to “include the population within the urban area of the city, as well as people who regularly socialise, shop or work within the city, and live in small towns and rural areas surrounding the city. It is important to note that GCCSAs do not define the built up edge of the city. They provide a stable definition for these cities and are designed for the output of a range of social and economic survey data.”
This statement has been prepared based on information available at 3 pm on Saturday 1 June 2019. 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, 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.
Where temperature area averages are mentioned, they are derived from the ACORN-SAT dataset.
