Victoria in summer 2010-11: Wettest summer on record in Victoria.

The summer of 2010-11 has been the wettest in Victoria since records began.

With final data still to be processed in the coming days, Victoria has already received a statewide averaged rainfall total in excess of 300 millimetres for the season.

This breaks the previous record for the highest summer rainfall in Victoria of 237 millimetres, set 100 years ago in 1910-11. The average summer rainfall in Victoria is 121.1 mm.

Gippsland is the only area of the state to record near normal rainfall totals for the season.

Victoria endured significant rainfall and flooding events during each of December, January and February. These events contributed to the state recording its:

      5th wettest December on record, and wettest since 1992;

      Wettest January on record;

      Wettest February since at least 1973, and provisionally the 6th wettest on record.

Daytime maximum temperatures were below average across Victoria this summer, while overnight minimum temperatures above average. Additionally, there were also a below average number of very hot days and very cold days for the season.

In Melbourne, the maximum temperature exceeded 40 degrees on two occasions during the summer on December 31 and February 1.

Australia is feeling the effects of one of the strongest La Nia events ever observed. The last time such a strong La Nia occurred was in 1973-74.

Ocean temperatures around Australia are near record high levels, and this summer has seen more frequent low pressure systems over Australia as well as much cloudier and more humid conditions than usual.

The very strong La Nia is the primary cause of the very wet summer we have had.

Whilst any one such event cannot be attributed to global climate change, a recent study of extreme weather events across the globe suggests that there has been an increase in the frequency of such events over recent decades, and this trend is consistent with what we expect under global climate change.

The current La Nia event is now past its peak and will continue to gradually decay during autumn. Bureau of Meteorology computer models suggest a return to more neutral conditions later in the year.

With the La Nina event weakening, rainfall across Victoria during autumn 2011 is likely to be close to normal. However ocean temperatures around Australia are still high, and so maximum and minimum temperatures are likely to be above average during autumn.

Notes

A Seasonal 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 9 am on Tuesday 1 March 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.
