Victoria in Autumn 2009. 

This table is based on preliminary data

This statement was prepared before all data for the period were available. This may affect some of the statistics presented.

Useful rains during both March and April, and a mainly dry May, resulted in totals for the entire autumn season being only modestly below normal in most parts of Victoria. Altona, with a seasonal total of 62.8 mm, was among a few places, that registered their driest autumn on record. The western third of the State, which benefited from a rainy spell during the fourth week of May, finished up with mostly close-to-normal totals for autumn.

A cold snap with widespread showers towards the end of April allowed substantial snow to accumulate for a few weeks over the higher northeast ranges, but a warm period late in May melted much of this snow.

Over the season as a whole, overnight temperatures averaged mostly near to or slightly below normal, whilst daytime temperatures averaged mostly near to or slightly above normal.

An archive of previous seasonal summaries for Victoria is also available, as are summaries for other states and many other climate summaries and diagnostics.

Notes

This statement has been prepared based on information available at 2 pm on Friday 29 May 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 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.

Based on preliminary data

This statement was prepared before all data for the period were available. This may affect some of the statistics presented.
