Victoria in September 2018: second-driest on record
September rainfall was very much below average across much of Victoria including small areas of lowest on record, making it the State's overall second-driest September on record and driest since 1914. The clear skies and dry soils meant that night time temperatures were very much cooler than average across northern Victoria, but daytime temperatures were generally close to or warmer than average.
Second-driest September
- September rainfall for Victoria as a whole was 66% below average, making it the State's second-driest September on record and driest since 1914
- September continued a run of nine consecutive months of below average rainfall for Victoria as a whole
- Rainfall totals were below average throughout the State, with much of the Mallee and a small area in far East Gippsland receiving less than 20% of their September average
- The lowest rainfall totals were in the Mallee, where September totals were less than 10 mm through most of the district and Mildura Airport recorded just 0.8 mm
- The highest totals for the month were in West Gippsland, with Balook the State's wettest site with 107.2 mm
- In the Northeast, some areas had monthly rainfall deficiencies of more than 100 mm
- For the State as a whole, the wettest day was on the 7th, when a low pressure trough and cold front brought moderate falls to central and northeastern Victoria, with the highest recorded daily total being 40.4 mm at Falls Creek (Rocky Valley)
- Numerous sites had either their lowest total September rainfall on record or their lowest total September rainfall for at least 20 years
Coolest nights since 1994
- Victoria's mean minimum temperature was 0.96 °C cooler than average, the lowest for September since 1994
- Night time temperatures were very much below average across northern and central Victoria, including a large area of lowest on record that covered much of the Mallee and Northern Country districts, and neighbouring parts of the Wimmera
- Several sites across the State had their lowest September temperature on record
- Numerous sites had either their lowest September mean daily minimum temperature on record or their lowest September mean daily minimum temperature since at least 1994
- Daytime temperatures were close to average across most of the State, but above average in East Gippsland and areas of central and northern Victoria
- The overall mean temperature for Victoria was just 0.01 °C cooler than average, which after several years of warm Septembers, made it the State's overall coolest September since 2010
- Coldstream had its lowest September mean temperature on record, and Mallacoota had its lowest September mean temperature since 1995
Severe winds at times
- Wind gusts in excess of 100 km/h were recorded at sites around Victoria several times during the month as cold fronts crossed the State
- The strongest wind gust recorded during September was 131 km/h at Wilsons Promontory Lighthouse on the 15th; Mount William in the Grampians and Mount Buller also recorded gusts over 100 km/h during the month
- After two very windy months in July and August, the total wind run at sites around Victoria was generally close to average

Notes
The Monthly climate summary, generally published on the first working day of each month, 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. More extensive discussion of significant weather events, along with later information and data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review.
This statement has been prepared based on information available at 10 am on Monday 1 October 2018. Some checks have been made on the data, but it is possible that results will change as new information becomes available.
In some situations, some or all of the rainfall is in the form of hail or snow. In these cases the totals given are for the water equivalent: the depth of liquid water that results from melting any frozen precipitation. There can be significant 'undercatch' of snow in strong winds, meaning the true precipitation can be higher than that reported.
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.
Where temperature area averages are mentioned, they are derived from the ACORN-SAT dataset.
