Victoria in summer 2016–17: A mild end to a warm summer

Average daytime temperatures were warmer than usual in most parts of Victoria during summer 2016–17. Overnight temperatures were warmer than usual in the east. Summer rainfall was drier than normal in parts of the southeast but generally close to average elsewhere.

Near-average rainfall for the State but very dry in East Gippsland

Another warm summer

  • The mean maximum temperature for Victoria over summer 2016–17 was 1.13 °C above average
  • Daytime temperatures in December and January were very much above average (monthly anomalies of +1.75 °C and +1.76 °C respectively)
  • In contrast, daytime temperatures in February, historically the warmest month of the year for Victoria, were slightly cooler than average (an anomaly of -0.12 °C)
  • Victorian overnight temperatures during summer were 0.60 °C above average
  • Overnight temperatures in December and January were more than 1 °C above their long-term averages, whilst night-times in February were cooler than average (an anomaly of -0.46 °C)
  • The last time Victoria recorded a cooler than average summer mean temperature (the average of the maximum and minimum temperatures) was summer 2004–2005
  • The exceptional heat in southeast Australia in early 2017 affected some of Victoria, although southern areas escaped the most severe conditions
  • A few Victorian stations set records for their warmest summer night (highest daily minimum temperature)

Notes

The Seasonal 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 2 pm on Wednesday 1 March 2017. 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.

Where temperature area averages are mentioned, they are derived from the ACORN-SAT dataset.
