Canberra in 2014: a warm year with a dry finish
Canberra experienced very warm daytime temperatures during 2014 with many hot days. While rain was close to average, conditions were generally dry during the second half of the year.
- Equal-fifth-warmest year on record
- Third-warmest mean maximum temperatures on record
- Equal-record number of days above 40 °C
- Below average rainfall, particularly during July to November
The mean maximum temperature at Canberra Airport during 2014 was 21.5 °C, 1.8 °C above the historical average. This is the third-warmest year on record for Canberra, and was associated with several warm spells during the year and a lack of cold conditions. There were 3 days when temperatures reached at least 40 °C, equalling the 2009 record, while 19 days reached at least 35 °C, nearly four times the average of 5 days. In contrast, the mean minimum temperature was just 0.2 °C above average, with the coldest August for minimum temperatures since 1994. The mean temperature was consequently 1.0 °C above the historical average, the equal-fifth-warmest year on record for Canberra.
Canberra Airport recorded 568.6 mm of rain during 2014, slightly below the historical average of 614.4 mm. Most of the rain fell during the first half of the year, with particularly heavy rain causing widespread flooding on 19 and 20 February. Drier conditions emerged between July and November associated with persistent high pressure systems and a lack of major rain events, with total rainfall for those 5 months 44% below average and the eighth-lowest on record. In total there were 103 rain days, 20 of which brought at least 10 mm, close to the historical average. Only 3 days exceeded 25 mm at the airport, with heavy falls around the ACT reaching 86.4 mm at Torrens to 9 am on 20 February, 48.6 mm at Tuggeranong on 4 April, 48.2 mm at Torrens on 7 December, and 38.2 mm at Tharwa on 27 March.

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.
The annual 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, 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 9 am on Tuesday 6 January 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
(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.
