Australian Monthly Climate Summary: June 2008

Tuesday 2 July, 2008

In Brief

June 2008 was dry across much of southern Australia, particularly in the eastern wheatbelt and the south coast of Western Australia. In contrast many central and northern areas of the continent recorded above average rainfall for the month. It was a warm month for maximum temperatures across most of the continent, particularly on the western slopes of the Great Divide. Most of the eastern half of the country also recorded warmer than average minimum temperatures during June. Consequently, it was the seventh warmest June on record for Australian mean temperature.



Maximum temperatures were above normal over most of the country, with the national average anomaly the 11th warmest on record and 0.97°C above the long-term (1961−90) mean of 21.45°C. The western slopes of the Great Divide through New South Wales and Queensland were particularly warm with large areas recording maximum temperatures more than 2°C above average. Most of the south and east of the continent recorded temperatures between 1 and 2°C above average. Victoria (+1.60°C, 3rd highest) and Tasmania (+1.68°C, 2nd highest) were particularly warm. Only relatively small areas of the continent experienced below normal maxima, the largest being the eastern Kimberley (WA), southeastern NT and eastern Cape York (QLD).

Minimum temperatures were also above average across the entire eastern half of the country during the month. Some areas of central QLD and around the ACT recorded minimum temperatures over 3°C above average. NSW (+1.94°C, 4th highest) and VIC (+1.90°C, 3rd highest) recorded particularly warm minima. In contrast much of the western half of the continent recorded average to below average minimum temperatures. Parts of the southwest and far northwest of WA recorded minima 1 to 2°C below average. Despite the east-west contrast, the nationally averaged minimum temperature was the 11th warmest on record and 1.00°C above the long-term mean of 8.93°C.

With maximum and minimum temperatures above average across much of the continent the national mean temperature for June was the sixth warmest on record, 0.99°C above the long-term mean of 15.19°C.

Rainfall averaged over Australia was very close to normal despite strong variability across the nation during the month. Much of southern Australia recorded drier than average conditions through June. It was the thirteenth driest on record for Victoria, and much of the southwest of the continent recorded below average rainfall. The eastern wheatbelt and the southern coastal district of Western Australia recorded very much below average rainfall. Lowest on record June totals were observed through a large area of southeastern WA stretching from Israelite Bay (east of Esperance) to Hopetoun and north to around Kalgoorlie. Large areas of southern and northwestern SA and northern and eastern Tasmania recorded below average to very much below average (decile 1) rainfall.

Two bands of average to above average rainfall stretched across the country: one from the northwest to the far southeast of WA, and another more significant one from the Kimberley (WA) to northern NSW and southern Queensland coasts. Resulting from a northwest cloudband that developed from the 8th to the 10th of June, with widespread and locally heavy rainfall, this second region included extensive areas of decile 10 totals. Straddling far northeast SA and far southwest Queensland border was a small area which had its wettest June on record. The remainder of northern Australia recorded patchy areas of above and below average rainfall.
