Queensland in August 2021: second-warmest August on record

Rainfall was above average in the north and central coast of Queensland, and below average in the south-west and south-east quarter of the state.

It was the second-warmest August on record in terms of mean temperature, behind 2009. Both mean maximum and mean minimum temperatures were above average, and the fifth- and third-warmest on record respectively.

Above average rainfall in the north

• Rainfall was above average across the north and central coast of Queensland, but below average in the south-west and south-east quarter of the state.
• Total rainfall this August was less than in August 2020, but more than in 2019.
• Heavy showers across the far north at the start of the month saw Coconut Island and Horn Island report their highest August daily rainfall on record.
• A surface trough and upper-level disturbance triggered showers and thunderstorms over the north tropical to central coasts and adjacent inland districts on the 30th, with widespread moderate falls recorded.
• A few sites in the north, or central coast and Whitsundays had their highest total August rainfall on record or their highest total August rainfall in 20 years.
  

Second-warmest August on record

• Queensland's mean temperature was 2.13 °C above average and the second-warmest on record (after 2009).
• The mean maximum temperate was the fifth-warmest on record at 2.04 °C above average, and the warmest since 2017.
  
• There were some very warm days at the end of the month, and on the 29th Sweers Island in the Gulf of Carpentaria had its highest August temperature on record.
• The mean minimum temperature was the third-warmest on record, and 2.22 °C above average.
• Above average minimum temperatures were common throughout August, and a few sites had their warmest August night (highest daily minimum temperature) on record.
• The persistent warm nights resulted in some sites reporting their highest August mean daily minimum temperature on record or their highest August mean daily minimum temperature for at least 20 years.
• Some sites had their highest August mean temperature on record or their highest August mean temperature for at least 20 years.
