2005 - AUSTRALIA'S WARMEST YEAR ON RECORD
2005 was the warmest year on record for Australia. The national average of 1.06°C above the 1961-90 mean broke the previous record, set in 1998, by 0.26°C.
All twelve months of 2005 were warmer than normal, but April was particularly exceptional. It was the warmest April on record over about two-thirds of the continent. In terms of the departure from normal, April 2005 was the warmest month ever recorded in Australia - 2.58oC above its 1961-90 mean.
It was a warm year over virtually the entire continent. While most locations have had at least one hotter year in the past, the extent of the above-average temperatures was unprecedented. The only region which was cooler than normal in 2005 was a narrow strip along the coast of Western Australia between Carnarvon and Bunbury.
2005 was also a very warm year globally, ranking with 1998 as one of the two warmest years on record for the world.
