Rainfall
Flooding rains and one of the wettest spring seasons on record in Victoria culminated in the state recording its 5th wettest year, following particularly wet La Niña years during the 1970’s and 1950’s. Almost two-thirds of the state received rainfall totals very much above the long-term average in 2010. In fact, several stations in the North Central district recorded their highest total rainfall on record, including Alexandra (Post Office) (1100.8 mm), Lancefield (1071.0 mm), Mansfield (Post Office) (1120.1 mm), Redesdale (1098.0 mm) and Yea (1056.8 mm). Mildura Airport and Bendigo Airport both doubled their usual annual rainfall in 2010 and many stations state-wide recorded their highest total rainfall since the early 1970’s.
Although Victoria observed several wet months early in 2010, most of the rain was recorded in the second half of the year. Persistent wet conditions through these months were driven by record warmth in the tropical waters around northern Australia. The strong La Niña event in the Pacific Ocean, coupled with warm sea-surface temperatures off the north-west coast of Australia, created conditions conducive to the formation of north-west cloudbands. These systems brought tropical moisture to Victoria from September to December and led to above average rainfall across the state, but particularly in regions north of the Divide.
The wettest locations in the state were in the Alpine area, with Falls Creek (Rocky Valley) taking the honours for the wettest spot in the state, recording in excess of 3000 mm for the year. Notably, after 14 years of dry conditions, Melbourne Regional Office recorded its first year of above average rainfall. Rainfall totals surpassed 1996, the last year to record above average rainfall at this site. In contrast to the prevailing wet conditions, Gippsland stations did not observe the deluge experienced to the north of the Divide, yet the region still managed rainfall totals close to the climatological average.
Maximum temperature
Maximum temperatures across Victoria in 2010 were very close to the long-term average. The southern half of the state experienced, on average, warmer daytime temperatures than usual. Melbourne Regional Office, Gabo Island Lighthouse, East Sale Airport and Wonthaggi all recorded average daytime temperatures significantly higher than usual.
Port Fairy AWS recorded its highest temperature on record, a sweltering 44.3 °C on the 11th of January. This same day was by far the warmest of 2010 state-wide, with most stations registering temperatures in excess of 42 °C and Avalon Airport reaching a scorching 45.7 °C.
In contrast, some locations in northern Victoria recorded annual minimum temperatures that were cooler than normal, including the Eildon Fire Tower, Swan Hill Aerodrome and Horsham Aerodrome. Not surprisingly, the Alpine region experienced the coldest daytime temperatures in the state, with Mount Hotham the coolest, averaging just 7.7 °C for the year and a chilly -5.3 °C on the 28th of June.
Minimum temperature
Also consistent with the high rainfall, night-time temperatures for the year were above average across Victoria, which experienced its 6th highest average minimum temperature on record. Most locations recorded night-time temperatures significantly higher than usual, especially Melbourne Regional Office which was 1.9 °C warmer than normal, whilst Essendon Airport and Wilsons Promontory Lighthouse were both 1.1 °C warmer than usual. Gabo Island Lighthouse recorded the warmest nights overall this year, averaging 12.7 °C.
The high pressure belt was further south than usual throughout 2010 which, combined with record warm sea surface temperatures in the Australian region, lead to more frequent high humidity events. These events were particularly prominent in late November and early December. Overnight temperatures were much warmer than usual throughout late summer and early autumn, with February to April 2010 the 3rd warmest for Victoria. Night-time temperatures were very close to usual in winter, whilst spring ranked as the 8th warmest, due to an especially warm November.
The standout for the warmest night for the entire state was the 12th of January, with numerous locations, particularly in the Mallee, reporting temperatures exceeding 28 °C. In fact, some locations registered their warmest night (highest daily minimum temperature) on record in 2010, with Maryborough, Castlemaine Prison and Bendigo Airport all reporting their warmest overnight temperatures on the 12th of January (28.9 °C, 28.5 °C and 27.3 °C respectively). Melbourne Regional Office recorded its equal highest overnight minimum temperature, a stifling 30.6 °C early in the morning of January the13th.
Some significant weather events in 2010
Hail: Severe thunderstorms developed to the northwest of the Melbourne Metropolitan Area and moved through the city from early afternoon on the 6th of March, progressing to the eastern suburbs and then into West Gippsland later in the afternoon. The thunderstorms were associated with large hail and heavy rain resulting in widespread flash flooding as well as water and hail damage to property.
Snow: 2010 brought a bumper snow season to the Victorian Alps with particularly heavy falls throughout August. Late season snow fall in mid-October to low levels was unusual; however unseasonable snow falls were also reported in mid-December.
Flood: Significant rainfall events during September and December resulted in two major flood events across Victoria. The rainfall associated with the September event (4th-6th) was widespread, but concentrated to the north of the Divide, resulting in major and moderate flooding spanning the north from the east to the west of the State. Several sites recorded their highest river levels on record including Clunes, Doherty’s and Yawong Weir, all recording peak levels over 5m.

Notes
A Annual 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.
This statement has been prepared based on information available at 8 am on Tuesday 4 January 2011. Some checks have been made on the data, but it is possible that results will change as new information becomes available.
Averages 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.
