2019 was Brisbane's hottest year on average, Queensland's sixth-hottest

Last year was, on average, Brisbane's hottest year on record and Queensland's sixth-hottest, according to the Bureau of Meteorology's annual climate summary.

On a national scale, Australia sweltered through its seven hottest days in December, melting many records including for the country's highest fire danger and its warmest and driest year.

Annual rainfall across Queensland was also 20 per cent below average in 2019 and large areas of inland south-east Queensland had their driest year on record.

The year started with Tropical Cyclone Penny, which dumped more than 110 millimetres of rain on far north Queensland and generated wind gusts of almost 100km/h on New Year's Day.

This was followed by Tropical Cyclone Trevor in March, which tore rollers doors apart with destructive wind gusts and brought much-needed rain to drought-affected areas.

There was significant flooding in and around Townsville in late January to early February, as well as extensive flooding from February into April in the Gulf Country and western Queensland.

It was a dry year overall in the south-east, with some locations reporting their driest year on record including Esk, Gatton, Somerset Dam, Amberley, Wivenhoe Dam, Logan City and Brisbane Airport.

In terms of temperatures, temperatures were more than a degree warmer than average for the mean, maximum and minimum temperatures in Queensland.

Many sites, mostly in the southeast, had their highest average daily maximum temperature such as Gatton, Rockhampton Airport, Amberley, Coolangatta, Brisbane Airport and Toowoomba Airport.

Queensland also recorded its warmest January on record, its warmest December on record and the highest December average maximum temperature.

Annual average maximum temperatures in greater Brisbane were also much warmer than usual with records broken at Brisbane, Gatton, Amberley and Archerfield.

The mean daily maximum temperature for Brisbane was 27.8 degrees, which was 1.2 degrees above the long-term average and the highest on record for Brisbane.

The combination of extreme heat and low rainfall meant the bushfire season started early in many parts of Australia and reduced the window for firefighters to backburn.

The Forest Fire Danger Index – gauging temperature, humidity, wind speed and drought to assess the potential threat of the spread of fire – was the highest on record over most of Australia.

Globally, 2019 was also the second-hottest year on record based on data going back to 1880.
