October was wetter than average in much of southern Victoria, and Wellington Shire was no exception.
According to the Bureau of Meteorology’s October Climate Summary, released last week, east Sale received 78.6mm during October, bringing this year’s annual total past 620.8mm.
This means the area has now officially had its first above average year for rainfall since 2016, with the weather station’s average annual rainfall notching 589.6mm.
Last year, east Sale only fell a measly 2.2mm short of its average.
Last month, Giffard nearly reached its October average of 52.2mm, clocking up 50.4mm.
More than 586mm has already fallen in Giffard this year, meaning the area has surpassed its yearly average of 560.3mm.
The shire’s north has also had a wetter than average October, with 101mm falling in Briagolong last month — nearly double its October average of 60.9mm.
The town’s total is 706mm so far this year, which is far higher than its yearly average of 654.2mm.
Balook, just north of Yarram in Wellington Shire’s south, broke its record for highest October daily rainfall, with 55.4mm falling on October 1.
Similarly, Traralgon and Morwell also broke their high October daily rainfall records, with 40.6mm (with 20mm falling in a 30 minute period) and 42.2mm respectively.
Traralgon had its highest October total rainfall on record, with 116.6mm falling, with a minor flood warning issued for Traralgon Creek on October 14.
It was a similar picture across most of southern Victoria, with the October rainfall total about 10 per cent more when averaged across the state.
A complex low pressure system and an associated low pressure trough that crossed the state at the end of September, resulted in widespread rainfall across Victoria on October 1.
Mid-month, a complex low pressure system and a low-pressure trough brought severe thunderstorms, strong winds, and widespread, locally heavy rainfall.
A cold front that crossed Victoria on October 22 resulted in light to moderate falls over the central and southern parts of the state.
While a cold front and the associated low pressure system which developed over western Victoria on October 28 brought damaging winds, severe thunderstorms, hail and showers.
Victoria’s cool season (April to October) rainfall total was around two per cent below average.
Daytime temperatures were close to average across most of the state away from Victoria’s south-west and parts of the Gippsland and north-east districts.
Averaged across the state, the mean maximum temperature was 0.43 degree Celsius below the October average, the lowest since 2016.
There were several warm days, notably on October 9, 21, 22, 27 and 28 because of a northerly airflow ahead of the approaching cold fronts.
Night-time temperatures were warmer than average in the state’s south-east.
Victoria’s mean minimum temperature was 0.10 °C below average, the lowest since 2016.
There were some cool nights scattered throughout the month; the lowest daily minimum temperature in the state this October was −6°C, recorded at Falls Creek on October 25.
Damaging winds affected Victoria on October 28 and 29 because of a low pressure system and the associated cold front.
The strongest wind gust of 146 kmh was recorded at Wilsons Promontory Lighthouse on October 29.
Victoria’s State Emergency Service received more than 2000 calls for help, mostly for fallen trees and building damage, as parts of the state — including Wellington Shire — were left without power for several days.
