Every month during 2013 recorded above-average daytime temperatures. January, July and September all broke their long-term monthly records, and winter was the equal-warmest on record.

There were 52 nights below 0 °C during the year, slightly below the historical average of 60 days, but only two nights dropped below -5 °C (average 7 nights). Night-time temperatures were well below average during both autumn and spring, but above average during winter. October and November were both more than 2 °C below normal, with several severe frosts causing widespread agricultural damage during October.
The very warm daytime temperatures but the only slightly cool nights meant the mean temperature for Canberra Airport was 14.0 °C, 0.9 °C above the historical average.

Since March 2010 the official station for Canberra is 070351 'Canberra Airport'. Averages from the previous site, 070014 Canberra Airport Comparison, are used for comparisons (all years of record).
An Annual 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.
This statement has been prepared based on information available at 10 am on Friday 3 January 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
(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.
