Victoria in spring 2008
Wet end to spring.

A very dry September followed by a very dry October, meant that Spring rainfall totals, overall, were below the long-term (all years of record) normal in most Districts, notwithstanding the good rains during November, which were largely on account of the development of cloud bands ahead of cold fronts, and several east coast low developments later in the month. The development of the cloud bands was related to a sharp warming of the ocean to the north of Australia.  

Daytime temperatures were above average in most Districts, but overnight temperatures were close to average.

In the Melbourne CBD, the average minimum temperature was 11.3 deg C (1.8 deg C above the long-term average over all years of record), whilst the average maximum temperature has been 21.5 deg C (1.9 deg C above the long-term average). Total spring rainfall was 78.8 mm, well below the long-term average of 183.6 mm.

The Melbourne CBD is usually warmer than the suburbs on account of what is known as the "heat island effect", a feature of the inner areas of most major cities.  This effect occurs on account of the ability of the buildings and roads to absorb heat (and then to re-radiate it back into the atmosphere) more effectively than grassland and forest.

This point is effectively illustrated by the fact that, away from the city centre at Melbourne Airport, average temperatures were not as high. The average spring 2008 minimum temperature at the Airport was 8.9 deg C (0.3 deg C above the long-term average), whilst the average spring 2008 maximum temperature was 21.0 deg C (1.9 deg C above the long-term average).

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 11 am on Monday 1 December 2008. 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.
