Averaged across the State, it was the driest June in Victoria since 1944 and the coldest for overnight temperatures since 1972.

Details

Temperatures

Average minimum temperatures were generally between 0 and 6 degrees, although in the Northeast the average was between −3 and 0 degrees. Across Victoria the average minimum temperature was the second lowest on record for June (−2.13 degrees below average).

The average maximum temperatures were mostly between 12 and 15 degrees except in the Northeast where maximum temperatures averaged between 9 and 12 degrees. Maximum temperatures were mostly within 1 degree of normal for June throughout Victoria.

Due to the cold nights during June, the mean temperature across Victoria was the third lowest on record (−1.09 degrees below average).

Rainfall:

Rainfall totals across most of Victoria were well below average (third lowest June average on record), except for East Gippsland, where periodic lows off the coast during the month gave the area average rainfall.

The rest of Victoria was dry, particularly the West Coast and West Gippsland regions due to blocking high pressure systems. Ballarat had its lowest June rainfall on record (12.8 mm, average 55.3 mm) while a number of stations had their lowest rainfall for at least 20 years including Melbourne 8.6 mm (previous lowest 8.0 mm in 1858) and Nhill 4.2 mm (previous 3.5 mm in 1930).

Significant Weather Systems

Victoria was dominated by slow-moving high pressure systems during June 2006.

Early in the month a low pressure system off the east coast of Victoria brought significant rain to East Gippsland, with Orbost receiving 42 mm on the 2nd.

A significant front and associated rain band moved across Victoria from the 23rd to 24th of June and a number of weaker fronts crossed the state in the last week of June.


Melbourne Summary

Melbourne recorded only 8.6 mm of rain for June, which was the second lowest June total on record, the lowest being 8.0 mm in June 1858. The Central (Metropolitan) district recorded its lowest June district average rainfall (18.9 mm) since the records began in 1890 (average 74.1 mm), the previous lowest being 20.1 mm in 1972.

The night-time temperatures (average 6.3 degrees) were also below average (7.2 degrees) with Melbourne experiencing the coolest nights since 1982 (average 5.6 degrees).
