Canberra in August 2014: Coldest August nights since 1994

Dry conditions continued during August, with Canberra Airport recording less than 60% of the August average rainfall and only three days with more than 1 mm (average 7 days). Daytime temperatures were above average, with only one day dropping below 10 °C (average 4 days) while 14 days reached at least 15 °C (average 7 days), consistent with generally clear conditions. However, minimum temperatures were the coldest since 1994 and the equal-fifth-coldest on record.

Notably, Canberra Airport had eight consecutive nights below -4 °C between the 2nd and the 9th, the equal-longest cold spell on record with June 1965 and July 1962. This included four consecutive nights below -6 °C, dropping to -7.6 °C on the 5th, the coldest night in Canberra since -8 °C on 29 July 2011 and the coldest August night since -8.5 °C on 9 August 1994. In total, Canberra recorded 15 nights of -2 °C or lower, twice the historical average and the most cold nights since 1994.

Notes

As of March 2010, the official station for Canberra is 70351 'Canberra Airport'. Averages from the previous site, 70014 Canberra Airport Comparison, are used for comparisons.

A Monthly Climate Summary is prepared to list 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, usually published in the fourth week of the month.

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 Monday 1 September 2014. 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 20 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.
