Brisbane temperatures were close to average for 2015. Both mean maximum and mean minimum temperatures were within 1 °C of the long-term average for all metropolitan sites. A warm spell affected the metropolitan area between 15 and 18 January, with the hottest day of the year occurring at Amberley; on 17 January with 39.4 °C. In contrast, cold conditions were experienced in mid-July, with very cold nights occurring between 15 and 19 July, including the coldest night of the year which occurred on 18 July at Amberley with-1.8 °C. On 17 July, it was the coldest day of the year at all metropolitan stations, where no station exceeded 16.6 °C during the day.

Rainfall was above average across the metropolitan area, with the Brisbane site recording its second-wettest year since 2000. Some notable rainfall events during the year included heavy falls between 20 and 22 February due to the remnants of ex-tropical cyclone Marcia tracking over the southeast, with current Brisbane Airport site receiving its highest February rainfall total since records began in 1996. Flash flooding occurred in some south Brisbane suburbs on 21 March, associated with heavy rainfall. Between 1 and 5 April, numerous sites in the metropolitan area recorded daily rainfall totals in excess of 100 mm due to a slow-moving surface trough affecting the southeast. Brisbane Aero recorded its highest April daily rainfall and its highest April rainfall total since records began at the current site in 1996. At the start of May, very heavy rainfall led to flash flooding in northern suburbs of Brisbane as a deepening surface trough and an intense low pressure system formed off the southeast Queensland coast. Bondall and Logan City recorded their highest May daily rainfall on record on 2 May. July, which is typically the driest month of the year in the metropolitan area, was particularly dry, with Archerfield recording 10% of its July average. Above average rainfall was recorded across most of the metropolitan sites for the remaining months of the year.

Some severe thunderstorms affected the metropolitan area throughout the year. Large hail was reported from various Brisbane metropolitan suburbs in January, March, and all spring months.
