# Climate of Brisbane

"none" is preferred when the title is sufficiently descriptive; see [[WP:SDNONE]]
Brisbane has a humid subtropical climate (Köppen climate classification: Cfa) with year-round period with warm to hot temperatures. Brisbane generally experiences 3 months of mild cool winter from June to August.

## Temperatures

Brisbane experiences an annual mean minimum of 16.6 °C (62 °F) and mean maximum of 26.6 °C (80 °F), making it Australia's second-hottest capital city after Darwin. Seasonality is not pronounced, and average maximum temperatures of above 26 °C (79 °F) persist from October through to April.
Due to its proximity to the Coral Sea of the Pacific Ocean and a warm ocean current, Brisbane's overall temperature variability is somewhat less than most Australian capitals. Temperatures only occasionally reach 35 °C (95 °F) or more. June and July are the coldest months, with average maximums of about 22 °C (72 °F); maximum temperatures below 20 °C (68 °F) are rare. Brisbane has never recorded a sub-zero minimum temperature (with one exception at night), and minimums are generally warm to mild year-round, averaging about 21 °C (70 °F) in summer and 11 °C (52 °F) in coldest month.

### Records of temperatures

The city's highest recorded temperature was 43.2 °C (109.8 °F) on Australia Day 1940 at the Brisbane Regional Office, with the highest temperature at the current station being 41.7 °C (107.1 °F) on 22 February 2004; but temperatures above 38 °C (100 °F) are uncommon. On 19 July 2007, Brisbane's temperature fell below the freezing point for the first time since records began, registering −0.1 °C (31.8 °F) at the airport station. The city station has never dropped below 2 °C (36 °F), with the average coldest night during winter being around 6 °C (43 °F), however locations directly west of Brisbane such as Ipswich have dropped as low as −5 °C (23 °F) with heavy ground frost. In 2009, Brisbane recorded its hottest winter day (from June to August) at 35.4 °C (95.7 °F) on 24 August; The average July day however is around 22 °C (72 °F) with sunny skies and low humidity, occasionally as high as 27 °C (81 °F), whilst maximum temperatures below 18 °C (64 °F) are uncommon and usually associated with brief periods of cloud and winter rain. The highest minimum temperature ever recorded in Brisbane was 28.0 °C (82.4 °F) on 29 January 1940 and again on 21 January 2017, whilst the lowest maximum temperature was 10.2 °C (50.4 °F) on 12 August 1954.

## Precipitation

From November to March, thunderstorms are common over Brisbane, with the more severe events accompanied by large damaging hail stones, torrential rain and destructive winds. On an annual basis, Brisbane averages 124 clear days. Dewpoints in the summer average at around 20 °C (68 °F); the apparent temperature exceeds 30 °C (86 °F) on almost all summer days.
Brisbane's wettest day occurred on 21 January 1887, when 465 millimetres (18.3 in) of rain fell on the city, the highest maximum daily rainfall of Australia's capital cities. The wettest month on record was February 1893, when 1,025.9 millimetres (40.39 in) of rain fell, although in the last 30 years the record monthly rainfall has been a much lower 479.8 millimetres (18.89 in) from December 2010. Very occasionally a whole month will pass with no recorded rainfall, the last time this happened was August 1991.
From 2001 until 2010, Brisbane and surrounding temperate areas had been experiencing the most severe drought in over a century, with dam levels dropping to 16.9% of their capacity on 10 August 2007. Residents were mandated by local laws to observe level 6 water restrictions on gardening and other outdoor water usage. Per capita water usage was below 140 litres per day, giving Brisbane one of the lowest per capita usages of water of any developed city in the world. On 9 January 2011, an upper low crossed north of Brisbane and dropped rainfall on an already saturated southeast coast of Queensland, resulting in severe flooding and damage in Brisbane and the surrounding area; the same storm season also caused the water storage to climb to over 98% of maximum capacity and broke the drought. Water restrictions have been replaced with water conservation measures that aim at a target of 200 litres per day/per person, but consumption is rarely over 160 litres. In November 2011, Brisbane saw 22 days with no recorded rainfall, which was the driest start to a November since 1919.

## Wind

Brisbane also lies in the Tropical Cyclone risk area, although cyclones are rare. The last to affect Brisbane indirectly was Severe Tropical Cyclone Oma in February 2019. The city is susceptible to severe thunderstorms in the spring and summer months; on 16 November 2008 a severe storm caused tremendous damage in the outer suburbs, most notably The Gap. Roofs were torn off houses and hundreds of trees were felled. More recently, on 27 November 2014, a very strong storm made a direct hit on the city centre. Described as 'the worst storm in a decade,' very large hail, to the size of cricket balls, smashed skyscraper windows while a flash flood tore through the CBD. Wind gusts of 141 km/h (88 mph) were recorded in some suburbs, many houses were severely damaged, cars were destroyed and planes were flipped at the Brisbane and Archerfield Airports. Dust storms in Brisbane are extremely rare; on 23 September 2009, however, a severe dust storm blanketed Brisbane, as well as other parts of eastern Australia.

## Temperature of sea
