Canberra in June 2015: Cool nights, mild days, rain mid-month

The start of June was cold in Canberra, with overnight temperatures dropping to −7°C, but daytime temperatures were generally above average. Rainfall was above average, almost all of it falling over four days in the middle of the month.

  • A cool start to the month
  • Days mostly warmer than average
  • Near to above average rainfall

Rainfall was average to above average across the ACT during June. Canberra Airport recorded 55.2 mm for the month, above the long-term average of 40.4 mm. Almost all of the rain fell between the 16th and 19th as a trough and complex low pressure system crossed New South Wales. Mt Ginini recorded the highest falls during the event with 32.4 mm observed in the 24 hours to 9 am on the 17th.

The mean maximum temperature for the month was about 1.5 °C above the long-term average despite some cool temperatures associated with the mid-month rainband. Maximum temperatures were warmest from the 12th to the 15th, with another brief warm spell towards the end of the month. Minimum temperatures were about 1.8 °C below average driven largely by a series of cold nights between the 2nd and 7th. Canberra Airport recorded the coldest temperature for the month, dropping to −7 °C on the 2nd. This is a June record for the current site (which opened in late 2008), although the record June minimum temperature at the old Canberra Airport site stands at −8.5 °C, recorded on 8 June 1957.

Notes

Observations for Canberra Airport are taken from the current site (Bureau number 070351), which opened in late 2008. Comparisons are made against data from the previous site (070014), which ran from 1939 to 2010.

The Monthly climate summary lists the main features of the weather in Canberra 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.

A climate summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 10 am on Wednesday 1 July 2015. 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.

The ACORN-SAT dataset is used for temperature area averages.
