Victoria in October 2014: Warm days and dry in the north and west

October rainfall was below average across Victoria, resulting in the driest October for the State since 2008. Most of western and northern Victoria received less than 40% of the long-term average rainfall. However, parts of east Gippsland recorded above average rainfall resulting from a low pressure system off the central NSW coast during mid-month.

Maximum temperatures were well above average across Victoria during October, with a number of locations in the north and west recording their highest monthly mean maximum temperatures. For the State, the October mean maximum temperature was 3.38 °C above the long-term average. The warmest period occurred on the 22nd as a stationary low pressure trough over central and north western Victoria directed northerly winds across the state which resulted in day time temperatures between 5 and 15 degrees above the October average at many locations.

Mean minimum temperatures were 0.58 °C above the long-term average for Victoria, with generally warmer overnight temperatures in the south and east of the State. Record highest monthly mean minimum temperatures were recorded at Alpine locations including Falls Creek, Hunters Hill and Mount Hotham.

  • Dry in the north and west, with below average rainfall for the State
  • Record run of days above temperature thresholds (for maximum temperature) in the north and west
  • Well above average daytime temperatures for the State
  • Warm nights in Alpine locations.

Notes

A Monthly Climate Summary is prepared to list the main features of the weather in Victoria using the most timely and accurate information available on the date of publication; it will generally not be updated. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review, usually published in the fourth week of the month.

A Climate Summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 9 am on Monday 3 November 2014. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

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.

The ACORN-SAT dataset is used for temperature area averages.
