Australia smashed its temperature record in the year to the end of June, beating a high set during the most recent El Nino weather event in the Pacific.

Buried in the Bureau of Meteorology's monthly report on national conditions, the agency noted the 12-month mean temperature was a "solid highest-on-record" result.

In fact, mean temperatures were a full 1.08 degrees above the long-term average, smashing the previous record July-June anomaly by 0.18 degrees. The previous record was set in the 12 months to June 2010 – an El Nino period.

“The July-June year anomaly can be interesting as it provides a way of examining conditions across the warm season as a whole, which can capture the influence of signals such as El Niño and La Niña,” the bureau said.
