Victoria in July 2015: Rainfall below average; some frosty mornings

For most of Victoria, July rainfall was generally average to below average; above-average rainfall was recorded only in the east and over parts of the Melbourne metropolitan area. Maximum temperatures were below average across the State. Minimum temperatures meanwhile were generally below average throughout Victoria with warmer-than-average areas southwest of Melbourne and in the east.

  • Statewide rainfall 15% below the long-term average
  • Some freezing mornings
  • Strongest wind gust 128 km/h at Wilsons Promontory

A series of cold fronts crossed the State during the month, bringing rain throughout Victoria. Several marked cold fronts brought snow to elevated areas and were accompanied by strong and gusty winds. A low developed east of Victoria on the 12th July and resulted in high rainfall totals in the far east. In contrast, in the northwest of the State totals were mostly below average, with large areas recording less than 60% of the long-term mean for July. The highest registered total for the month was 306 mm at Falls Creek. The wettest day during the month was the 13th, when many sites recorded daily rainfall totals of more than 60 mm.

Maximum temperatures were below the July average across Victoria, with the statewide average −0.39 °C below the long-term mean. Low maximum temperatures were caused by powerful fronts that swept across the state leaving cold air in their wake. There were some very cold days particularly mid-month with the coldest temperature of −4.3 °C recorded at Mount Hotham on the 14th. The warmest day across the state was the 21st when northerly winds brought warmer conditions and many places recorded daily temperatures above 15 °C. The highest maximum daily temperature recorded during the month was 20.4 °C at Lakes Entrance.

Minimum temperatures were also below the July average across the State with the exception of the east and parts of the south-central areas. The statewide average was −0.50 °C below the long-term mean for the month. The 3rd saw cool temperatures across the north and west of Victoria, with many places recording overnight temperatures below zero. Another spell with frosty mornings across most of the State was on the 19th and 20th and some places recorded their lowest minimum temperatures for a decade. The lowest minimum daily temperature recorded during July was −6.9 °C on the 17th at both Falls Creek and Mount Hotham.

Notes

The Monthly climate summary lists 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.

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 August 2015. 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.
