Melbourne in June 2017: drier than average with warm days and cool nights

June 2017 was much drier than average across Greater Melbourne. Daytime temperatures were generally warmer than average, particularly during the middle of the month, while overnight temperatures tended to be cooler than average.

Much drier than average

  • June 2017 was much drier than average across all Melbourne suburbs and surrounds
  • Almost all sites across Melbourne had fewer rain days than average: Essendon Airport, Oakleigh and Springvale, for example, each had around half their average count of rain days for June
  • Most areas of Greater Melbourne received less than half of their average June rainfall
  • Rainfall in Melbourne's north was slightly closer to average, but still had little more than half of its June average rainfall
  • June rainfall ranged from 26% of average at Laverton RAAF to 54% of average at Essendon Airport
  • Wallan (Kilmore Gap) had its driest June on record and two sites had their lowest total June rainfall for more than 40 years

Warmer than average days and cooler than average nights

  • Daytime temperatures were generally warmer than average during June
  • Only two sites across Greater Melbourne had cooler than average days for June: next to the beach in the bayside suburb of Frankston, and in the northeast at Coldstream
  • Generally clear skies and light winds meant Melbourne's overnight temperatures were cooler than average
  • The coldest nights were at Coldstream, which averaged minimum temperatures that were 1.9 °C below average for June

High pressure systems dominate

  • Mean sea level pressure was more than 5 hPa above average for June across much of southern Australia
  • The dominant high pressure systems reduced the number of rain-bearing low pressure systems and cold fronts affecting southern Australia
  • Many sites that measure air pressure daily across Melbourne reported their highest monthly 9am mean sea level pressures for June on record
  • Average wind speeds were much lower than average for June across Melbourne

Most values are the precipitation in the 24 hours to 9 am on the day indicated. Days marked with → are part of a longer accumulation, which is shown on the final day.
Values over 100 mm have been rounded to the nearest whole millimetre.
Days marked with - have a rainfall report of zero; days left blank have no rainfall report (which often indicates no rain fell).

Notes

The Monthly climate summary, generally published on the first working day of each month, lists the main features of the weather in Melbourne 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 9 am on Monday 3 July 2017. 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.
