Victoria in July 2008

A cold and wet July

Summary

July's average rainfall across much of Victoria has revived hopes of many. But it is reasonable to refer to the rainfall as "catch-up". It hasn't produced much run-off and a dry autumn following more than a decade of below average falls has meant that the ground has soaked up almost every drop. Low pressure systems shearing off from a broad trough over the Southern Ocean have been responsible for most of the precipitation.

It has also been cold, with most overnight and daytime temperatures averaging about half a degree below normal. The cold weather, combined with the precipitation, has resulted in good snowfalls over the alps.

In Melbourne, the average overnight minimum temperature was 6.8 deg C (normal 6.5 deg C) - the lowest average minimum since July 1998, when the average was 6.1 deg C, whilst the average daytime maximum temperature was 14.2 deg C (normal 13.7 deg C). Rainfall totalled 44.2 mm (normal 48.8 mm).

Much of Victoria has nearly a 50% chance of the wet weather continuing over the next three months (August to October). Specifically, there is a 50% chance of above normal falls in the south of the State, whilst in the Mallee there is a 40% chance of above normal falls. Most of the rest of northern Victoria has a 45% chance of exceeding normal rainfall. However, the cold weather is not likely to continue, there being a 70% chance of above normal temperatures over the next three months.Jump to:  Extremes  Records  Summaries  Notes  the top
