Victoria in 2008
Mostly dry with warmish days and coolish nights

Summary

Notwithstanding the relatively cool and wet end to the year, Victoria's weather in 2008 was mostly characterised by dry conditions with the clear skies promoting relatively warm days and relatively cool nights. The main influential and repetitive feature of the synoptic weather maps during the year was a persistence of high-latitude blocking anticyclones over Western Australian longitudes. This feature directed relatively dry air over the continent for much of 2008. Towards the end of the year, sea surface temperatures rose steadily over waters to the north of Australia, and  allowed for the invasion of considerable moisture across Australia. An archive of previous annual 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 Monday 5 January 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.
